On the spur of the moment I decided to go to White Salmon to pick up the carbon fiber tubes I had made for the little yellow trimaran. Innovative Composites Engineering.
I also got a tour of the place. Amazing. Stuck in the woods outside of White Salmon. Space X is their biggest customer. They have giant presses to compact the laminate even more than bagging. I wasn’t allowed to take any pictures inside the building. And also warned not to touch anything.
They consulted on Oracle. Hence in the boneyard.
When I ordered the carbon fiber cross tubes for my yellow 12′ trimaran, I assumed a modulus of about 16 million. And I speced the thickness accordingly.
I just got the spec sheet from the manufacturer.
8.5 x 10 to the 7th.
I checked with a scientist I know. That is 85 million.
That is more than 5 times the modulus. Wow.
They aren’t going anywhere.

I stumbled on this list that I made years ago. It still looks pretty good. I need to study it carefully for changes but again it looks pretty good.

SOURCES
DECEMBER 28, 2012 KURT LEAVE A COMMENT EDIT
A big mess of sources. I worked on a lot of these during the last few trips. I imagine this kind of being crowd sourced where people will add to this as it goes along. Some to be added anyway, but getting it out for what it is now. I see it doesn’t let me hot up the links. To get hot links, put sources in the search engine and load the one from years ago.

A sources list now is different than it was when I first did the Construction Manual. Presently the best way to locate boatbuilding products is to go to the manufacturers website, and from there find the vendors in your local area. This list is pretty much for North America. And it leans toward products that I have first or second-hand experience with. Builders elsewhere, get me your favorites and I will expand this.

confess I was surprised how cheap these things are).

I just had a meeting with a rep from TriStar Plastics Corp. This is the

plastics equivalent of a steel service center. They stock plastic, machine

plastic and will provide technical advice on what is best for a particular

application. Interestingly they make a wide variety of bearings which would

seem ideal for rudders etc. www.tstar.com
