Title:
MOLDING MATERIAL, ASSEMBLY OF MOLDING MATERIALS, METHOD FOR PRODUCING MOLDING MATERIAL, AND METHOD FOR PRODUCING ASSEMBLY OF MOLDING MATERIALS
Document Type and Number:
WIPO Patent Application WO/2018/083978
Kind Code:
A1
Abstract:
The present invention provides an assembly of molding materials, each of which is obtained by covering a carbon fiber bundle that contains an impregnation assistant with a thermoplastic resin. This assembly of molding materials is configured such that 30% or more of the whole assembly is a molding material that satisfies 100 ≤ F/L (N/m), where L is the molding material length in the axial direction of the carbon fiber bundle and F is the grip force of the carbon fiber bundle with respect to the molding material. Consequently, falling-off of carbon fibers from the molding materials during injection molding is able to be prevented, so that a molded body is able to be produced with high production efficiency.
