Trying out slower and calmer pacing on this one - lemme know what ya think!

"Let's go on a tangent!"
spends over half the video on the tangent

Good stuff, thank you

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.

As an engineer these are honestly the best videos, loving it, more tangents please

Bo Jarnard has done it yet again. Fantastic video.

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.

Former composites M&P engineer here. The reason for the moisture pockets is because phenolic resin curing causes water to be formed. With such a thick section of phenolic, it is hard to impossible to evacuate all of the moisture formed during the cure.

[bmatt]

I read phenol as "feenol", so when someone says "this curry needs more fennel" there's way less paperwork.

Let's get a rally goin for the early viewers baby

@BreakingTaps did an excellent video comparing Starship and Space Shuttle tiles, including examining samples of each using an SEM for chemical analysis and even making his own tiles. Unfortunately, it seems that video has been taken down which is a shame.

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.

i love your tangents joey i promise i do please keep going on them because i think the same way and i love seeing how it comes back around

[ryanrising]

I’ve also had that same experience where the further back I go the better information is available. That’s a disturbing trend, and I hope it doesn’t continue.

me at 16:40 : Damn that phenolic liner took a hard hit if its that charred all around
me at 20:20 : ITS NOT EVEN PHENOLIC! YOU TRICKED ME, CARBONATED MILK MAN!!!11!!11

awesome video as always :P

[jackfrost]

A guy was selling whole heat shield tiles on Ebay. I questioned the guy and ended up buying one. After I received the tile and I asked him "where did you get this"? he answered, "I pried it off of a Russian space shuttle on display in Russia". LOL, I feel bad but happy I have it.

I like the pace of this one. It let's ideas breathe for a moment before continuing with more details. 👍

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.

Very nice and informative video. Everything about your video screams “I am an engineer and I love learning, experimenting, and creating”. Enjoyed your video.
