How to make a boat out of wood and fiberglass for fishing czcams.com/video/2lTQgPnx5fQ/video.html
Very clever
Hi, i've noticed all vartm show parts so far use glass mats. Would this technique work with fabrics, carbon or glass, or would permeability be an issue without flow medium ? Thanks
Hi AeroGarage, VRTM processes are fine using other fabric types such as Carbon, Aramids (Kevlar), Hemp etc. You are absolutely correct that factors like permeability need to be considered, understanding this before you construct you VRTM mould is crucial in order to manufacture components without defects. Permeability of the fibre and resin viscosity are just a couple of the factors we consider when designing our injection/ venting strategy. Thank you for your comment.

Hello. How many copies possible to make until that silicon bag get damaged?
Hi Max, It is difficult to predict an exact number of cycles as this will depend on the type of resin being used, the complexity of the shape and the general care taken by the operator. However, we have many customers using this technique successfully and several hundred cycles are possible (using polyester resin) Have a look at this case study on our website. Between 250 and 300 are achieved in this application. siliconecomposites.com/production-success-with-silicone/
only works with small projects and projects without many complicated wrinkles
We're interested to know why you think this technique is so limited. We have customers using it very successfully at various levels of complexity and at different scales.
@@Compositeinteg1 It would be great to see a more complex shape, Love the product already
How come? The silicone bag follows the complicated shape and wringkles, so it fits much much better than conventional nylon plastic vacuum bag. It saves time, and material.
@@ericww1993 you clearly didnt work with any complicated shapes
@@RePlayBoy101 So just explain it why? We need explanation and proof instead of statement
Excellent
Thanks Khaled!
Excellent
Thanks for sharing this video, so informative. We are doing some LRTM process tests. In some cases, we observed a strange thing. Once we observe that the resin completely fills the cavity and comes up from the outlet valve and moves through a hole to the excess resin catch pot, we stop the resin injection. Then, we observed that the resin in the mold is sucked out to the excess resin catch pot. In other words, while we disconnected the resin supply, we observe resin flow in the hose which connects the outlet to the excess resin catch pot. In fact, some amount of resin does not stay in the cavity and moves to the catch pot. Have you had any similar experience? Thanks in advance for your advice.
Hi Masoud, from your description it sounds like there must be a vacuum leak into your mould somewhere. If the mould is fully vacuum-tight the flow of resin into the catch pot will stop when you stop feeding the inlet with resin. Some flow may continue while the mould relaxes but it certainly shouldn't empty the cavity.
Excuse me, how to continue to vacuum when the resin is cured? Can the resin not be drawn?
I'm not sure that I understand your question. I'm happy to help if you can explain a little more.
I’d hate to do that day in and day out.
Hi, If you don't like the look of this process you would really hate the traditional hand-laminating process! Maybe you're safest staying on the beach!!
Здорово!
How is the mold made? He wants to make himself a boat, but my mold is the biggest problem. How to do the final product does not stick to the mold. I'm sorry about the bad English and I hope you understand what's the problem.
We use a 'release agent' to protect the mould and to stop the resin and gelcoat from sticking to the mould. In this application we used material from Marbocote (www.marbocote.co.uk/)
good one czcams.com/video/BctLHxO8HEM/video.html
Can you mention the list of products used throughout the process and where can I buy them at your website? Gelcoat, resins, fibers, core, seals etc.?
This is really a waste of time. I worked at eliminator boats we could have laid that boat up in half the time. The guy brushed the gel coat on he should have used a spray gun for consistent thickness. I also noticed they didnt glass stringers in either for rigidity full lenght of hull.
I'm sorry that you feel this is a waste of time but, with respect, I think that you have missed the point. We have used this small hull to demonstrate the principal of infusing large composite structures. Our customers are successfully using this principal to infuse laminates which consume up to 8 tons of resin (boat hulls, turbine blades etc) Hand laminating on this scale is not an attractive proposition! Regarding the lack of stringers- the structure of this hull is irrelevant as it is not a commercial product- however, the final product includes an internal seat/floor moulding which is bonded in place and which provides rigidity. Spray gelcoating would of course be preferable in a 'production' situation. Anyway, thanks for watching!
sorry how about using simple vacuum mould manufacturing sisal composite....epoxy resin is it available
Beautiful. Do I understand correctly that for boat optimizing total weight vacuum infusion using a silicon top mold would be better than RTM light to have more fiber per weight? I'm just curious. Of course it's possible that with the need for ballast on a sailboat this really doesn't matter since you even want a bit of weight in the hull. And for a dingy... it's probably more important to be able to easily keep it clean :D
An 'infusion' type process (either with a reusable silicone bag or a conventional disposable vacuum bag) could result in a thinner laminate with a higher fibre content but this would depend on the type of fibre being used and the other process parameters. With a vacuum bag one can use flow-mesh to accelerate the resin over the compacted fibre so you're not depending entirely on lateral flow. However, the laminate achievable in this type of RTM process is perfectly adequate for this application and, as you point out, the smooth inner surface is a big advantage!

Hi i wounder if my proyect is 0.8 mt width,0.8 mt long and 50mm deep, can your system help?, and if yes how long time it takse till you finish the injection of that big quantity of resin - about 9kg
It's hard to say exactly how long it would take to inject this mould as this will depend on the resin viscosity and the fibre type and content. However, an injection rate of approximately kg per minute is generally achievable. The size is no problem and we have experience of building and using moulds much bigger than this.
Compositeinteg1 thanks alot I need your phone num.
No problem- the main office number is +44(0)1752849998
What kind of resin you use ?
The resin that is injected into the finished mould is a standard polyester injection grade resin.
Seems like a complicated machine just to make a very small flat panel.
I can understand your comment! However, this type of mould is often used to make rather 'special' small flat panels that are used to generate test coupons for structural analysis of composite laminates. The processing parameters and dimensional tolerances must be controlled to a very strict tolerance. Most of these moulds go into laboratory environments.
kg?
Approximately 18kg of resin was used in this hull infusion.
Obshy weight of the boat and Width laminate?
I'm not sure that I understand your question but the total weight of the Hull (glass and resin) is approximately 36kg
ОК
I am not sure i completely understand the construction of this form. There should be a gap between central part (that can be moved) and outer part. How is this gap sealed?
The gap between the central plate and the outer flange is sealed with 'O' rings. These seals allow the central plate to slide up and down but maintain the necessary vacuum/pressure integrity.
Thanks! I have thought about that but was not sure. Very nice technical design of the whole form.
혹시 한국분들중에 이동영상을 보시는 FRP 고수분들동영상에서 제작자가 FRP섬유를 올릴때 한장만 올리는거 같은데 두께가 두꺼운 섬유를 한장 사용하여서 성형하는 것인가요? 아니면 여러장을 적층하여서 성형하는것인가요??
The hull laminate is formed with multiple layers of glass fibre reinforcement which are all infused at the same time. I hope this answers your question.
질문에 답변해주셔서 감사합니다!! 그러면 여러장을 적층할시에 섬유 한장 붙이고 수지바르는 식을 반복해서 성형하는 것인가요??
No, all the layers are moulded (infused with resin) at the same time.
also does mold b which is the top side touching the fibers when air tight, because i wonder how you got the nice finish... are you using releasing agents like wax and pva to release the top half of the mold aftr curing the part
Yes, both sides of the mould are coated with a 'semi-permanent' release agent which prevents the resin from adhering to the surfaces and maintains a good finish. We generally use the release system from Marbocote (www.marbocote.co.uk)
hello, great video... would like to know how much this mould would cost and how can i get it touch to purchase jus the mold and air ejector assembly.
Hi Samuel, Thanks for your positive comments. if you contact us via our company email (info@composite-integration.co.uk) we can send details and pricing.
Is the green mold plastic?
The green mould is a conventional 'composite' laminate. It's made with vinylester resin and glass fibre. The green surface is the vinylester gel-coat.
+Compositeinteg1 does it have to be a composite? Is that the reason you added the gel coat into the mold so there wouldn't be a problem when to other resin was injected to the fiber?
The white gelcoat was added simply to provide a good surface finish to the final moulded hull. The mould is coated with a release agent so this gelcoat (or the injected resin) doesn't bond to (or damage) the green mould surface.
Hi, you use a tempered glass or an Acrilic like the B side? if my proyect is 1 mt width, 2 mt long and 3mm deep, what kind of material you recomend for my B side?
Hi, we use heat-toughened (tempered) glass for the upper half.
When adjusting the cavity thickness, what is the gap between the peripheral resin channel, and the upper glass mold? He sits the depth gauge on the channel walls, but there must be space above that for resin to enter the fiber pack. In other words, the depth gauge reading won't be the final thickness of the panel, correct? Thanks!
Yes, you are absolutely correct. The gap between the resin channel and the top mould is 1mm and so this is taken into account when adjusting the cavity thickness.
Hello! Is that also possible using a 2K Polyurethane liquid system instead of the polyesther resin? I guess a different equipment would be necesssary, but I was wondering if, theoretically, can work any way! Thank you
Hi Stefano, Yes, this type of mould can potentially be used with a PU system. The type of equipment necessary would depend on the material specification but feel free to contact us if you'd like us to look at this in more detail. Actually I have just uploaded a video that shows a similar mould but with a variable/adjustable cavity and a higher pressure rating that could also be of interest. Follow this link: czcams.com/video/XLFj4SLw_FY/video.html
Well done video! Wish I would have had this video five years ago when I started this project: czcams.com/video/wTwUg9BI6Uk/video.html
Gut gemacht!
+Александр Ненахов Thanks!
hi, how (where) is the air inyected to open the mould? And how you control the resin in the inyection line when you finish? thanks
+Puertas y Decoracion The Air is injected via an 'Air-Ejector' valve built into the lower mould half. You can see the end of this valve (black circle) in the centre of the lower mould at the start of the video. The resin is injected into the mould through an 'Injection Valve' and this valve is cleaned (flushed with solvent) as part of the cleaning cycle of the Ciject injection machine at the end of the process.
Do you have any photographs of the interior? What resin system was used and how long was the resin cure time before de-moulding? Thanks for any info. regards
Hi Jack I could provide some photos of the inside surface if you can send an email address. We used a standard Scott Bader injection grade polyester and it was left in the mould for about 45 minutes after the end of the injection to cure. (by the way, are you the ex-Falmouth student who designed the hull??)
+Compositeinteg1 I am the Ex-Falmouth student! I am working at Solent University now. My email is Jack.cunningham-burley@solent.ac.uk Glad to see the progression of the project. Thanks againJack
No problem- I'll send you some photos when I get a minute. The project has been very useful and we use it as a way to compare traditional infusion with the VRTM process. The VRTM hull is certainly a far more 'finished' moulding as it includes a foam core around the gunwale and has a nice smooth surface inside. We will be working on a mould to make the internal seat/floor structure and aim to have some of these on the water in 2016! Feel free to come and have a look if you're passing.
What does RTM stand for?
Michael Eliot Hi Michael, RTM stands for Resin Transfer Moulding. VRTM stands for Vacuum Resin Transfer Moulding and so implies that the mould is held closed solely by atmospheric pressure (vacuum)
+Michael Eliot Resin Transfer Molding
What would happen if there was no RTM machine, only vacuum sucking in the catch pot?
Koen Klijnsmit The machine is controlling the pressure of the resin at the inlet (small level of positive pressure). Without the machine the process would still work but it would be slower.
Thank you, i can not afford the RTM machione but i have a small vacuum pump. The 2 hard shells instead of 1 and a flexible bag just seems more accurate to me (if you calculated your tolerances correctly). That is why i was wondering if it would still work without a pushing force on the resin... To make it even more complicated, i need a mold that can become 100 degrees C, so i am thinking of putting Carbo e -therm between layers ( i can not find a more advances solution), then i don`t even need an oven anymore.
Koen Klijnsmit Yes, your process could potentially still work with only vacuum providing the transfer pressure.You might also look at the Fibretemp mould heating system from Germany- it could be relevant. www.speautomotive.com/SPEA_CD/SPEA2009/pdf/ET/ET-09.pdf
Thank you, that looks interresting. ^_^
How much apply vaccume in the catchpot and flange
The red string represented the resin perimiter flow channel? Where can you get that blue vacuum seal? Those little green circels coming out are your maximum depth stop? We didnt see you put vacuum on the perimiter?
Koen Klijnsmit All the seals and 'formers' used in the mould making stages are available from Composite Integration Ltd.Vacuum is connected to the perimeter flange as well as to the main mould cavity.
Compositeinteg1 Thank you, i can`t find the seperate products on the site...
