METHOD FOR PRODUCING MOLDED BODY

WIPO Patent Application WO/2022/190669

A1

Provided is a method for producing a molded body by stacking and compression molding: a composite material A including discontinuous fibers and a resin M1; and a composite material B including continuous fibers and a resin M2. An arrangement surface X of a molding die for the composite material B is a three-dimensional shape with a curved surface. The arrangement surface X is curved towards the bundle width direction of the continuous fibers. The relationship between the maximum thickness Tmax of the continuous fibers included in the molding die and the minimum thickness Tmin of the continuous fibers included in the molding die is 1 ≤ Tmax/Tmin ≤ 1.5. By this method for producing a molded body, even when using a molding die having a three-dimensional shape with a curved surface, for which the fiber orientation for continuous fibers is prone to disarray, disarray of continuous fibers can be suppressed and mechanical properties can be secured.
