<p>A carbon fiber-reinforced mouldable sheet is provided. The mouldable sheet comprises a thermoplastics resin and at least two reinforcing agents differing in the length/diameter ratio, which are incorporated with the thermoplastics 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 mouldable 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, mouldable articles made therefrom are excellent in mechanical properties, appearance and light-weight characteristic.</p> |
