Title:
RESIN COMPOSITION, PELLET, MOLDED ARTICLE AND METHOD FOR PRODUCING RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/124332
Kind Code:
A1
Abstract:
Provided is a resin composition obtained using a thermoplastic resin and regenerated carbon fibers, the resin composition exhibiting improved mechanical strength and excellent productivity. The present invention also provides: a pellet and molded article formed from the resin composition; and a method for producing the resin composition. Relative to 100 parts by mass of a thermoplastic resin, this resin composition contains 10-70 parts by mass of regenerated carbon fibers and 0.1-15 parts by mass of a functional group-containing compound. The regenerated carbon fibers: are obtained by firing a composite material of an epoxy resin and carbon fibers; and contain 5 mass% or more of a residue derived from the epoxy resin. When the resin composition is formed into an ISO multipurpose test piece having a thickness of 4 mm, the maximum bending strength thereof is 130 MPa or more.
