I got excited when I first saw this, but after looking a bit deeper it seems like it'd be of limited usefulness. It will lay down a coil or something, but it doesn't actually "weave" the CF. I guess you could make it do a sort of weave in certain cases, but mostly it looks like all it can do is either a coil or a series of short strips. Still nifty, but probably not usable to make random CF bits for cheap
I'm not sure that's 100% accurate. The last time I read up on carbon fiber, there was a different way of looking at it (circa 2003 research). First of all, carbon filaments have very high tensile strength and that's about it. In order to make this more robust, carbon fiber is weaved in very specific ways to provide strength in more than a bidirectional way. Unidirectional, plain , and twill weaves all were used for the addition strength in the weave in certain applications.
I really fail to see how a weave with multiple angular reinforcements could be weaker than a unidirectional layout that only has strength in polar movement. Could you explain it further by chance?
