Title:
RECYCLED CARBON FIBER-REINFORCED POLYOLEFIN COMPOSITION AND USE OF SAME
Document Type and Number:
WIPO Patent Application WO/2022/190857
Kind Code:
A1
Abstract:
The purpose of the present invention is to obtain: a recycled carbon fiber-reinforced polyolefin composition which contains recycled carbon fibers and still has a mechanical strength that is just as good as the mechanical strength of a composition which contains unused carbon fibers; and a molded body of this recycled carbon fiber-reinforced polyolefin composition. The present invention relates to a recycled carbon fiber-reinforced polyolefin composition which contains from 0.01 part by mass to 50 parts by mass of (A) a modified polyolefin, from 50 parts by mass to 99 parts by mass of (B) a polyolefin, and from 1 part by mass to 80 parts by mass of (C) recycled carbon fibers (provided that the total of the components (A), (B) and (C) is 100 parts by mass), wherein the modified polyolefin (A) is obtained by reacting (D) a modified polyolefin having a group that is reactive with a carbodiimide group and (E) a carbodiimide group-containing compound with each other.
