WIPO Patent Application WO/2022/215606
Kind Code:
A1
Abstract:
This method for producing a composite molded article comprises: a step for preparing a plurality of UD tapes, each of which comprises a tape-like base material sheet that is formed of a thermoplastic resin, and reinforcing fibers that are impregnated into the base material sheet in such a manner that the reinforcing fibers are oriented in the same direction; and a step in which the prepared plurality of UD tapes are continuously introduced into a mold, while being stacked upon each other, and subsequently heated, thereby obtaining a composite molded article that has a predetermined cross-sectional shape. A UD tape which has a thickness of 20 μm to 80 μm, a width of 0.5 mm to 10 mm and a weight per square meter of the reinforcing fibers of 30 g/m2 to 95 g/m2 is used for the above-described UD tapes.
