    Since CZcams is about to delete annotations, figured I'd post them here for everyone to see. Enjoy the video!
    0:01 The numbers in this video are generic data taken from official sources (such as DuPont) to demonstrate trends. Your material specifics may vary significantly. Always consult your material data from your manufacturer before designing a layup!
    10:14 What I more should've said was shock loading where the part is expected to not fail, as fibreglass and kevlar will do better here. Carbon is a very common material in impact attenuators because they are designed to permanently deform (fail) inwards. Carbons high stiffness allows you to use a tube like structure and be very strong in direct compression (10:19 in video) without buckling. You then use a geometry like a tapered cylinder or cone and it essentially folds in on itself, absorbing large amounts of energy as it progressively folds down. This is further helped by the thicker walls per unit weight for carbon, which means they have more bending strength on a skin basis. FIbreglass may have buckled in this scenario (on either a skin or whole structure level, not stiff enough), and kevlar is weak in compression, so carbon is the way to go.
    10:31 Kevlar fuel tanks: Kevlar has very high toughness and good abrasion resistance, and fuel tanks are a component that will only ever see very high loadings in tension, so Kevlar is appropriate here. I guess for the applications I was only really thinking bodywork

    This agrees with my experience building high performance power and sailboats. I worked with S glass, carbon, and Kevlar from about 1978 to 1998, it appears that things haven't changed much.
    Most of the failures I saw were compression failures, we quickly learned never to use Kevlar in compression. I think part of the problem is that it's hard to get Kevlar (basically a polyethylene, therefore "slippery") to bond to the matrix. It was always a pain in the ass to use, hated by all.
    I loved S glass, by far the best strength and stiffness / dollar, great in compression. With any fiber, but especially with glass you must make sure that the sizing is compatible with the resin you use.
    Carbon fiber, miracle shit. We built a 30' carbon fiber/epoxy/Nomex honeycomb sailboat hull and bracing (ca. 1988) that came off the mold at about 250 lbs, stiff as a brick. Two layers of 0/90 tow | Nomex honeycomb | 0/90 tow. Only issue? you could take a sharp pencil and smash it straight through the hull. We warned the purchaser not to do that...

Look carefully at compositeenvisions.com for their 3 (yes they cost something) videos explaining how to do professional layups. Com Envisions is the best place on the continent for exotics. Things are wild out there as some can use 3D software, 3D optical/lazer scanners to do near female mold quaulity with 3D printers. Now that Stratasys patents on their Ultem 9085 (PEE plastic)have lapsed a thin honeycomb & thin film covering both sides with a laundry list of prepegs vac bagged/autoclaved cheeper than female molding processes. Look at 3dp-platform.com i like their WorkBench Series #400 with bed size at 39" on "Y"axis by 57" on "X"axis by 27&3/4" on "Z"axis(folds thru house doorways & runs 45 to 55K$ depending on extruders and enclosures).

    • @JZStudiosonline
      @JZStudiosonline Před 5 lety +9

      I'm assuming that's 2 layers of 0/90, 2 layers nomex, and 2 layers more 0/90, otherwise that's insanely thin for a boat hull. Even still, that's thin for a hull. I've done aerospace stuff and am slightly triggered you didn't do any 45. We only use kevlar for things like belly panels that get lots of abrasions or internal "hinges" Otherwise it's not a very good structural component. Never tried stabbing it with a pencil, but a (I believe) 2 ply tailboom is practically unbreakable and works as a baseball bat.

    In sailplane construction, we use glass fibre extensively to handle bearing stress, where it outperforms aramid and carbon fiber. We use aramid in the crash protection zone of the canopy, where glass and carbon dust would be harmful in a crash. We use carbon fibre only where lightness and stiffness is important. Also, the stiffness you give for the raw materials is much greater than the fibre-matrix combination, with carbon fibre in an epoxy matrix having only a quarter of the stiffness of steel.

    @TheMaxaton Před 7 lety +7

    There's a bit more to it than that. Matrix materials are only as good as their design. By playing with the characteristics of the material used in junction with pattern design, part geometry and so forth you can easily rig up a design that makes one material excel over the other. This is true even in cases where the first material is better for the application on paper. For this reason you often see carbon in sailboat masts, for example, where flex to weight ratio is a key factor or even in rigid bike frames which often experience high momentary forces. This is also the idea behind enforcing carbon with kevlar. Furthermore, carbon parts also excel in the long run when you look at plastic deformation over time, due to applying bending and torsion forces to a geometry. This, in turn, lets us to look at the economics of materials science differently as well. The biggest problem with carbon fibre, however, is the lack of automation options in a production scenario... hence the price tag.

      I don't think manufacturers want flexible cars.
      If they did they wouldn't brag about making the car 25% stiffer from last years model every year.
      It may add a layer of comfort to commuter cars with cheap suspension, however on performance cars manufacturers don't want the body flexing and pulling the suspension out of alignment.

    • @nerome619
      @nerome619 Před 7 lety

      Beyond a certain point added chassis stiffness is a byproduct of other needs, usually NVH and crash worthiness. Plus OEM suspension bushes are often three-dimensional compliant, thus providing different suspension sets for different load conditions - chassis flex is far less of an issue for handling purposes than it was 15 years ago.

    @nerome619 Před 7 lety +7

    Ah no. I would suggest that the failure mode of S glass (if you can get it) is not superior to Kevlar. Kevlar is a curious material as you note. Being a form of nylon its failure more in some respects that of metal: when loaded to saturation the micro failures along the fibres allow for energy absorption, which can be very useful. However the fibres are very tough and so the composite will not break into pieces.
    I think you also have the thickness aspect of CF/FG backwards. You will need a thicker FG part compared to CF as the FG needs more material for the same stiffness - with the thicker laminate becoming stiffer in part due to beam theory. There is also the tooling and resin requirements for each fibre system to consider, you can use a poly/vinylester resin for the FG, but epoxy is best for aramid/epoxy.
    The 200gsm textreme CF is around $30/m.

    @IEleMenTIx Před 7 lety +21

    Hi! I need to clear up some things!
    So you are saying that High modulus Carbon fibers are essentially strands of diamonds?
    After 2800°C heat treatment of mesophase pitch-based Carbon fibers they reach a mean interlayer distance of 0.342nm. Ideal Graphite's is about 0.335nm, so MPP-based Carbon fibers are nearly Graphite fibers! The carbon atoms in graphite are sp2 hybridized. That's why MPP-based CFs are good electrical conductors. Diamond bonds on the other hand are purely sp3 hybridized, the bonds are saturated so there are no electrons to transport any current. Diamonds are insulators. It is also important to note that the microstructure of carbon fibers both pitch- and PAN-based are not 100% understood to this day.
    Side note: Diamond Nanothreads can be synthesized by applying huge pressure (200000bar) to benzene and slowly reducing the pressure to let the threads grow.
    Also I need to ask you something about your table of material strengths. I'd be glad if I could buy materials with these strengths off the shelves lol. Where did you get the data of Kevlar + Epoxy. 3500 MPa?
    Look, here is some tensile strength data of epoxy prepreg laminates from Hexcel which are basically available off the shelf:
    E-Glass:
    UD: 1100 MPa
    Fabric: 600 MPa
    Aramid:
    UD: 1100 MPa
    Fabric: 500 MPa
    High Strength Carbon:
    UD: 2000 MPa
    Fabric: 800 MPa
    Intermediate Modulus Carbon:
    UD: 2400 MPa
    Fabric: 900 MPa
    I think it would have been smarter to compare laminate strengths than pure fiber strengths. Pure fiber strength data is a marketing tool! PAN-based IM fibers are marketed with strengths over 7000 MPa. The data is gathered from tensile testing of single filaments with huge measurement errors that are sometimes larger than the measurement value!!!

    Dude F chopped strand. I really don't know what it'd be good for other than plugging a fekin' hole.
    There's different weaves in fiberglass as well. Mat, normal weave, satin, biaxial, triaxial even.. I've seen a bunch of variations. The type of cloth and weave can determine how much epoxy the cloth absorbs.
    I even glassed with canvas before... Which sucked b/c I spent a lot of time trying to work the epoxy into the cloth... Luckily it was West Systems 209, so cure time is SUPER slow in a 75 degree room.
    Sglass can be arguably different b/c it has a twist in the weave... However I've seen E-glass (verified cheap E glass) that had a twist in the weave too.
    S-glass is going to be a little more whiter than E-glass (greenish), but in comparison I think it comes down to how you're laying it. I made 2 fish tanks, same exact dimensions, glassed the inside of both tanks. Went e-glass the first time for my tank, s-glass the 2nd time for the customer's tanks. Used all the same dimensions, screw spacing, same number of layers, etc.
    The S-glass tanks bowed on the back side (where no glass was), the E-glass tank did not.
    Generalizing fiberglass in a video is kinda weird. There's variations in strength between 2 different e-glass sellers with the EXACT same weave.
    Then to get into the epoxy strength... Cure times of hardener, temperature outside, brand, UV resistance (because fiberglass strength is different on day # 5 vs day # 2000), etc... all this comes into play too.

      I actually bought a splash guard shields for my g35 (carbon fiber), on ebay a while back Well I broke the guard under my oil pan area by driving over a small branch. This was at factory height too. The small branch just kicked up and wacked the panel. I heard it crunch and knew immediately it was broken.
      Well it was only a long crack with a huge hole... So I peeled/cut away the loose pieces, propped it back into shape and threw a couple of satin weave fiberglass mats over it with West systems epoxy, 206 hardener... built a foil plug where the hole was...
      Babied it/formed it - until it got tacky. Let it cure. Fastened it on so it hinges forward for oil changes.

      I'm lowered now, and there was a huge rock on highway 75 (dallas) that was kicked up and broke into pieces like right in front of me (they closed that lane for a few days).

      ANYWAY! They make aluminum splash guards for 200$ now... probably sticking to my glassed guard though.

      ... Which material would be best for building a micro/mini drone frame?

    • @seigeengine
      @seigeengine Před 6 lety

      Well, drones are often made of carbon fiber composites, which are probably your best bet here.
      The light weight and high stiffness are going to be pretty important in a drone.

      Chopped strand serves to add bulk. In using glass vs say carbon, and if cost is more important than weight, use of chopped strand (or mat, it's the same thing) can add some bulk and give you a stiffer, albeit heavier laminate. Mat also serves a VERY useful purpose when using woven materials, especially heavier ones. If you try to apply several layers of woven, you have to have some cushioning between the layers, or you run the risk of delaminating under impact loads. In effect, the bumps in the woven material can sit on top of one another, resulting in half the laminate having glass against glass, while the other half is resin rich. Hit it with a strong enough impact and it will tear apart. Using a chopped strand mat gives a cushion, something to fill the space between opposing skins , allowing glass fibers to interlink between them, making delaminating MUCH less likely.

  • @gerhardkutt1748
    @gerhardkutt1748 Před 7 lety +8

    The most important discussion is competely missing here. All these materials are useless without the bonding material - Polyesters, Vinylesters, or epoxy. Without this added into the mix, all the theory on material strength is mute! It is a combination of the bonding material plus the glass, kevlar, carbon - and foam too. Strength to weight also not discussed - where polymer resins come in and play a big part. Then there is how the parts are manufactured - lay ups are important too. starting with base coat - whether it is a gel or if there is an absence of it. Good presentation, but incomplete and therefore misleading.

    Very informative and useful! Thanks for the efforth you put into this video. I would love to see a video where you do a comparison between the weave pattern because that is a factor as well as the material in terms of creating flexible/stiffer/tougher/stronger construction, also the combination of those.
    As well as clarifying the different kind of resins what they are good for.
    Personly i know a bit of them but it's still cloudy but there is people who might don't know these things.
