Title:
METHOD FOR MOLDING COMPOSITE MATERIAL, COMPOSITE MATERIAL, PRESSING HEAD, AND DEVICE FOR MOLDING COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/151426
Kind Code:
A1
Abstract:
Provided are a method for molding a composite material, whereby the occurrence of temperature unevenness in the composite material during heating is reduced, a composite material, a pressing head, and a device for molding a composite material. The method for molding a composite material has an electroconductive wire-shaped material arranging step and a magnetic field application step. The electroconductive wire-shaped material arranging step comprises arranging, in an unreacted composite material 10 having reinforcing fibers 12, a plurality of electroconductive wire-shaped materials 16 at an interval wider than the interval between the reinforcing fibers 12 along a direction intersecting with the reinforcing fibers 12 in the plane in which the reinforcing fibers 12 are aligned. The magnetic field application step comprises applying a magnetic field 42 in a direction intersecting with the plane in which the reinforcing fibers 12 are aligned.
