초록 ▼

A carbon fiber-reinforced moldable sheet is provided. The moldable sheet comprises a thermoplastic resin and at least two reinforcing agents differing in the length/diameter ratio, which are incorporated with the thermoplastic resin. One reinforcing agent (A) contained in the composite sheet is a carbon fiber having a length/diameter ratio of 200 to 30,000 and the other reinforcing agent (B) is a fibrous and/or powdery reinforcer having a length/diameter ratio of less than 50, and the contents of the reinforcers (A) and (B) in the moldable sheet are 5 to 30% by volume and at least 5% by volume, respectively, the sum of the contents of the reinforcing agents (A) and (B) being in the range of from 20 to 50% by volume. The reinforcing effect of the carbon reinforcing fiber (A) is enhanced by the fibrous and/or powdery reinforcing agent (B) filled among spaces of reinforcing fibers (A). Therefore, molded articles made therefrom are excellent in mechanical properties and appearance and light in weight.
