COMPOSITE MATERIAL, AND METHOD FOR MANUFACTURING MOLDED BODY

WIPO Patent Application WO/2022/030337

A1

Provided is a composite material containing a reinforcing fiber A and a matrix resin. The reinforcing fiber A is a discontinuous fiber with a fiber length of 5 mm or more, and the reinforcing fiber A includes a reinforcing fiber A1 with a fiber width of less than 0.3 mm and a reinforcing fiber bundle A2 with a bundle width of 0.3-3.0 mm. When the reinforcing fiber bundle A2 is divided into bundle width zones (the total number of bundle width zones n = 9) and the volume ratio of the reinforcing fiber bundle A2 in each bundle width zone is VfiA2, the composite material satisfies equations (x), (y) and (z) below. Also provided is a method for manufacturing a molded body using the composite material.　Equation (x): 0≤Vf(i=1) A2<10%, Equation (y): 0
