PURPOSE:To provide the titled compsn. having excellent rigidity and mechanical properties (particularly, repeated impact strength), by blending a polycarbonate, a rubber-contg. polymer and a bundled carbon fiber. CONSTITUTION:A carbon fiber (roving or chopped strand having a length of 10mm. or below) is immersed in a soln. of a nylon bundling agent (e.g. nylon 6 having a degree of polymn. of 100 or below) to deposit the soln. on the carbon fiber, and the fiber is then dried. The resulting carbon fiber contg. 0.5-10wt% bundling agent deposited thereon is used. 100pts.wt. polycarbonate such as Novadol 7,025A (a product of Mitsubishi kasei K.K.), 0.01-100pts.wt. rubber-contg. polymer such as MBS resin (acrylate/butadiene/styrene copolymer) and 5-100pts. wt. said bundled carbon fiber are blended together. |
