【答案】：Caron and graphite fibers are different in carbon content, pyrolyzing temperature, and modulus of elasticity. Graphite fibers have higher carbon content, pyrolyzing temperature and modulus of elasticity than carbon fibers.
Precursors for carbon fibers are PAN, rayon and pitch. In former times rayon was more used as a precursor and still is for certain specialized applications (rockets). Carbon fiber filament yarns are used in several proccessing techniques: the direct uses are for prepregging, filament winding, pu...

Unidirectional carbon fiber fabric is a type of carbon reinforcement that is non-woven and features all fibers running in a single, parallel direction. With this style of fabric, there are no gaps between fibers, and those fibers lay flat. There is no cross-section weave that divides the fib...
