Hardly a graduate level materials science video, but interesting nonetheless:

Its a show on the Discovery Channel, what do you want
. I have already seen it and remember being quite disappointed at how unskilled it appeared. 0 -

I like the discovery channel, but havent seen the carbon fibre Bike clip, as stewie says it's disappointingly low tech.I ache, therefore I am.0

Doing the donky work of laying up the carbon isn't that difficult, all be it a messy job. It's the design that's the difficult bit ! As I'm sure you know.
I'm sure that given the materials, and equipment, most of us could 'knock up' a carbon frame..... I'm pretty sure it'd be a pile of sh*te though !!
Interseting stuff never the less.........Science adjusts it’s beliefs based on what’s observed.
Faith is the denial of observation so that Belief can be preserved0 -
I enjoyed it. Had never seen how it was done before. I'm not so sure about some of the "low tech" comments. To me low tech would mean I could do it in my garage with
simple hand tools. I didn't see too much, in the way of tools, in that video, that I have laying around the house.0 -
Dennisn, I guess you’re right to suggest that aeroplane glue is far from low tech, manufacturers can glue almost anything these days, I (perhaps naively) imagined the whole assembly to be a bit more homogeneous, impregnated with resin under a vacuum and baked as one lovely carbon fibre thingy. I ache, therefore I am.0

How do the separate pieces of carbon mat stay together as they lay it up, does it have sticky stuff impregnated in it, in its sheet form?I ache, therefore I am.0

Did not someone post someone blog or somethong where you had made they own CB frame?0

These are probably pre-impregnated mats.To err is human, but to make a real balls up takes a super computer.0 -
Better coverage of the French 'Cyfac' Carbon frame company on youtube0

There are various lay-up techniques fo carbon - differing in complexity and cost - making the final components is quite straight-forward, but getting the design, lay up, tooling and processing correct is the tricky bit. We make some high-tech parts and the actual lay-up is classed as semi-skilled. Pre-preg is the easiest, but care needs to be taken in the cutting to get the fibre-orientation correct and then the lay-up in the moulds / around the mandrel. Once completed, the lay up is baked to soften the resin and typically using bladders, compression and vacuum to squeeze out the air and get the resin to bond between the fibres.Make mine an Italian, with Campagnolo on the side..0

CF and Bamboo instructions.
Bamboo should be fine unless you have Pandas in your area ?0 -
How do you make sure your frame jig is correct?
Do you need a Frame Jig Jig?0 -
And how to Felt et al make such fine weave add up? I can't get sheets of wallpaper to align properly from floor to ceiling so how they do it around curves?Commuter: Taped-up black Trek 2200 (FCN 5)

yes like 3k twil weave.0

As usual work have blocked, what i suspect to be, one of the more interesting links on here
