If you look at the link I posted above, you'll see what I believe is the answer to your question. Carbon fiber fabrics that contain other fiber types are readily available, with carbon/Kevlar being widely used in some products. I don't see it in the bike biz, however.
I think you misunderstood my post. I'm not talking about different fiber types.
CF fiber strands in a CF fabric are almost exclusively arranged in 'x' and 'y' orientations (in a flat, 2D layer) like the fabric in your clothing. Even if they are molded in tubes and other 3D shapes shapes, CF fabrics are still generally made in a flat plane. When multiple fabric layers are present, each fabric layer is fully separated by a resin layer and this causes delamination near the point of failure.
What I meant are long fibers arranged in all x, y, and also z orientations (3D). This means some of the fibers will be laid across multiple fabric layers. The present manufacturing processes prohibits such fiber orientations. Such fabric layup in theory would prevent delamination of the material all the way to failure leading to CF products with far greater durability and better able to withstand extreme application of forces.
