    I really miss old internet. Companies/people really just saw it as an information source akin to encyclopedia. Boring tech docs, material data sheets, grad student research, pedantic details of something that only a nerd would care about. A phone call would often result in direction to a webpage where you could get all the details.
    Now days it is more of a marketing platform. Don't show them anything that they could use to compare and choose a different product. "We give 30% more power than the competition." Never tell us what the baseline was, the direct numbers, or which competitor they are referring too. Just the puffery marketing.

      Probably another side effect of globalization. Foreign companies muscling in on markets so much that new customer capture via minimal online information became really important to sales. Get the prospect to call on the phone then sick a salesperson on them to manipulate them into a sale before they do too much internet searching and find a competitor.

      Honestly, it probably just comes down to companies becoming more concerned regarding ITAR compliance. Especially once a product has a defense application, the product and all associated info will be kept under wraps. Considering each violation equals up to $1 million in fines plus 10 years in prison, I definitely wouldn't want to risk it.
      Also, the specific example in the video of the Fiberform would almost certainly be ITAR controlled given its current application in spacecraft.

    Speaking of ablation, just the other week I had an operation on my back called radiofrequency nerve ablation. They put big needles in me right up against my spine, and then put mini microwave emitters down the needle and they basically "burned" my nerves to kill them off. It works wonders for my pain because I have degenerative disc disease and those nerves are constantly being pinched for no good reason.

      Hey man my specialists here in El Paso have been useless for my degenerative disk disease and treatment.

I just wanted to ask if you are getting this done in the US by any chance?

    • @kinexkid
      @kinexkid Před 16 dny +9

      @DirtStacks yeah, I'm in central california, just east of the bay area. The route I had to take to get the ablation approved by my insurance was to first go through two rounds of steroid injections in my back to see if it responded well to it. It gave me maybe a week of pain relief, but the do tor said thays a good sign because it means that they are targeting the right spot, even though the pain came back rather quickly. Some people respond really well to the injections and never have to step up to the ablation, but I definitely needed it. I didn't go through my regular doctor either, I went to a place that specialized in pain medicine and anesthesiology.

    How I ended up getting 20lbs of phenolic powder involves a two year voyage on making liquid carbon moldable composite parts which snowballed into making graphene and reading a ton of NASA white papers on heat shields. There's a few methods to using phenolic power sans formaldehyde, but is a bit more equipment intensive with higher levels of heat and pressure. Naturally I clicked on this video double time to see how your journey progressed.

      *No need for tiles at all. just drill lots of micro holes. then pump out dry ice out of those holes to form a cold co2 boundary layer. you dont even really need a pump. the heat of re-entry will cause melting of the dry ice and high pressure dry ice co2 to come out of the micro holes to form the boundary layer.*

I am guessing it's due to the tile from Starship 28 - SpaceX is pretty tight lipped about a lot of Starship; I can see how they wouldn't want that analysis just out there for it's competitors to see (Even though they obviously based it on NASA's work prior.).

    FMI employee here! You're right about ITAR and NDAs so I won't say much about our products. The reason the old FMI website is dead is because we were acquired by Spirit Aerosystems in early 2020. I literally just finished packing some PICA for shipment with our intern, and pulled up this video to teach him about what it is and how it works. I must not have watched all the way through last time! We were stoked for the shoutout, haha. And yes, SpaceX came to us years ago to ask about buying PICA, but the sticker shock led them to develop PICA-X with the help of NASA.

  • @lajoswinkler
    @lajoswinkler Před 16 dny +4

    The problem with drilling phenolic resin (Bakelite, etc.) is the dust that is formed. Wearing a respirator is not enough - there has to be intense ventilation like a fumehood. People often keep the respirator on while doing something and then just remove it. *The finest dust stays suspended in air.*
    Some composites would also use asbestos as the reinforcing material and grinding that is so much worse.
    Also, pyrolysis is not a straightforward process. It's not resin and then boom, carbon. All the brown gunk between it, all those smokes and vapors, those are some NASTY things, seriously carcinogenic and corrosive.
    Really good video.

    When it comes to ablative cooling or shielding, that is the same for normal construction wood. A well engineered wood building fairs better and longer than a steel structure, for the reason that wood has a 'defined' burn rate, it deforms little while it burns. While steel warps and tears apart much before it melts and fails.

    On a liquid Bi-prob I made back in the 90s I initially used standard fiberglass and an ablating resin as a liner and had good results.. I switched to a silica cloth with an overlapping weave and the engine would cough up what looked like fur balls as it de-laminated.. I switched back to fiberglass that would melt and coat the nozzle throat with glass preventing erosion and no more fur balls.

    Well, they say timing is everything. Your timing is excellent. They've been talking about heat shield panels on Starship on several channels this week. Thank you so much for sharing what you know. I'll have to share this 1 at the Makerspace this weekend.

    I work at the company that makes the material used in solid rocket motor nozzles for the gem 63 xls used on Vulcan (and other solid rocket motors but that's the coolest in my opinion) along with the PICA used in many NASA heat shields (not Orion, she's too wide for us to make stuff for, except the nozzles for the launch escape system, we make that stuff too). Cool to see some of the stuff I work on make it into a cool video like this.

    Fun fact: wood is a phenolic composite:
    cellulose with phenolic compounds crosslinked
    It does work as a heat shield, similarly good as other phenolic composites, but obviously inferior to optimized versions.

    I like that there are going to be more videos soon. since I subscribed when you did simplex one there were practically no videos but I guess you made a few and you are going to publish them now. I personnaly like that so you didn't forget the previous vids when the next one comes out

    I really like this pacing of video but i get why most might not. Maybe we need a BPS 2 channel which is for these slower videos? Idk maybe not. Either way really enjoyed this video.

    For analyzing composites like the phenolic-linen one in the video, if you wanna go crazy and look at the cross section to look at FVF, void content and other cool stuff, you could try casting and polishing the samples and then use a digital microscope. TBH I used to work in a lab that did this and it was cool when it worked but its a ton of effort. Also, I know you are very careful about safety and I always appreciate you mentioning it, but it might be good to wear a lab coat when you work with composites to keep the dust off your skin. I'm sure you have protocols in place for that but its a cheap and easy way to boost your safety.

    5:14 I'm not sure the description on how TEA-TEB ignition work is correct. I don't think trimethyl borate is used at all, and TEB contains the boron for the green flame.
    Both triethylaluminum and triethylborane are pyrophoric, with TEA being able to self ignite in contact with cryogenic oxygen. So the mixture is injected with the oxidiser into the combustion chamber first to start the fire, then the fuel is added and the TEA-TEB is shut off.
    I'm not entirely sure why triethylborane is used in addition to triethylaluminum, but my guess is that TEA alone is a bit too crazy on its own and TEB calms things down.
    Note; I'm not an expert. This is just my understanding from watching Everyday Astronaut and Scott Manly.

    Phenol and formaldehyhe were used as disinfectant in healthcare (typical smell of old hospitals). Formaldehyde is used even now for working with tissue samples in pathology.
