You sure?
With the right blend, layering (directions, thickness), combination of different fibres and the quality of the manufacturing (incl. autoclave treatment), you can get an extremely tough product, which isn't very brittle at all.
If the riders would focus less on the looks of the fibre, and more on the performance of the composite, we'd see drastical improvements in quality and strength. Example, if you look at the aircraft industry, you'll hardly see the 'classic' CF weave, but fibres in one direction only, or other kinds of fibre composites. Aramide or glass fibres are more resistant to scratching and general wear... The components turn out in a brown-yellow kind of colour, but perform better. :(
