Nitpick: fabric lay-ups are rarely used in industry because the weave exerts shear stresses on the fibers, making them weaker under load. Aerospace composites are all unidirectional.
But fiber blends are very common. It's typical to mix CF, glass, and aramids to get the price and properties you want, though I don't think it would make much sense to mix chopped and continuous fibers.
- eutectic 9y agoThanks for the correction, my bad. The technical term for the kind of thing I was thinking of is 'multiscale composites', and there already seems to be a lot written about carbon fiber/carbon nanotube mixed composites which would presumably be similar to carbon fiber/nano-cellulose composites. I obviously can't claim to be an expert, but there at least seems to be some precedent.
