PREPREG, PREFORM, MOLDED PRODUCT, AND METHOD FOR MANUFACTURING PREPREG |
摘要 |
<p>A prepreg is disclosed, comprising a reinforcing fiber base material impregnated with a thermoplastic resin, wherein the reinforcing fiber base material may comprise from 0 to 50% by mass of reinforcing fibers each having a fiber length of more than 10 mm, from 50 to 100% by mass of reinforcing fibers each having a fiber length of from 2 to 10 mm, and from 0 to 50% by mass of reinforcing fibers each having a fiber length of less than 2 mm, wherein the average of two-dimensional orientation angles each formed by a reinforcing filament (a) and a reinforcing filament (b) intersecting the reinforcing filament (a) may be from 10 to 80°, the thickness h0 (mm) at 23°C may be 0.03 to 1 mm, and the tensile strength à may be 0.01 MPa or more. The prepreg can be applied for thin molded products which have been considered unsuitable as a laminated molded product and can provide molded products that have a complicated shape and have isotropically high mechanical properties.</p> |
