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.

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.

@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.

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.

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.

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.

You are probably too young for this to concern you, but one thing about phenolic resin is that it is the first industrially produced synthetic resins. Production of Bakelite started in the naughties of the 20th century. When I started to be concerned with such stuff there were maybe 10 basic resins around and that told you most of what you needed to know to assess their suitability for a certain purpose. Phenolic (Bakelite) Melamin (Mica) UP, (unsaturated) polyester Epoxy Now entering the thermoplastics: PE, polyethyliene PP, polypropylene PA, polyamide (Nylon) PC, polycarbonate (Makrolon) PMMA, polymethylmetacrylate (Plexiglass) PU (Polyurethane) PTFE, polytetraflorethylene (Teflon) Therre were some exotics, but those about had you covered for most applications.

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.

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.

Have we notably improved on their performance/weight/mechanical characteristics at all since that time?
