Carbon Fiber Reinforced Polymers (CFRP) materials usually have laminate structure, providing reinforcing in two perpendicular directions. With the increase in the CNF aspect ratio ( l/d) up to l/d = 60, the longitudinal loss factor ( 11) decreases rapidly. The fracture toughness of carbon fiber reinforced plastics is governed by the following mechanisms: 1) debonding between the carbon fiber and polymer matrix, 2) fiber pull-out, and 3) delamination between the CFRP sheets. Milled fiber, for example, can be used as filler material to improve mechanical and electrical properties for plastic housings or covers. The aspect ratio of CNF was varied from l/d = 5 to l/d = 100.
