Abstract

Official abstract text for this publication.

Provided is a composition capable of providing a formed article that, even when using continuous fibers, has excellent interfacial adhesion between the continuous fibers and a matrix resin, and as a result, has excellent mechanical strength (e.g., impact resistance and flexural strength). One aspect of a composition according to the present invention includes a polymer (A) including an amino group, fibers (B), and a thermoplastic resin (C), in which a content ratio of the fibers (B) is 70 parts by mass or more and 250 parts by mass or less based on 100 parts by mass of the thermoplastic resin (C). Another aspect of the composition according to the present invention includes a polymer (A) including an amino group, a non-woven fabric (B′), and a thermoplastic resin (C).

First claim

Opening claim text (preview).

1 . A composition, comprising: a polymer (A) including an amino group; fibers (B); and a thermoplastic resin (C), wherein a content ratio of the fibers (B) is 70 parts by mass or more and 250 parts by mass or less based on 100 parts by mass of the thermoplastic resin (C). 2 . The composition according to claim 1 , wherein a content ratio of the polymer (A) including an amino group is 0.1 parts by mass or more and 10 parts by mass or less based on 100 parts by mass of the thermoplastic resin (C). 3 . The composition according to claim 1 , wherein the fibers (B) are carbon fibers. 4 . The composition according to claim 1 , wherein the polymer (A) including an amino group is a conjugated diene-based polymer. 5 . The composition according to claim 1 , wherein the fibers (B) each have a fiber length of 50 mm or more. 6 . A composition, comprising: a polymer (A) including an amino group; a non-woven fabric (B′); and a thermoplastic resin (C). 7 . The composition according to claim 6 , wherein the non-woven fabric (B′) contains recycled fibers. 8 . The composition according to claim 6 , wherein a content ratio of the non-woven fabric (B′) is 50 parts by mass or more and 150 parts by mass or less based on 100 parts by mass of the thermoplastic resin (C). 9 . The composition according to claim 6 , wherein the non-woven fabric (B′) includes carbon fibers. 10 . The composition according to claim 6 , wherein a content ratio of the polymer (A) including an amino group is 0.1 parts by mass or more and 10 parts by mass or less based on 100 parts by mass of the thermoplastic resin (C). 11 . The composition according to claim 6 , wherein the thermoplastic resin (C) is an olefin-based resin. 12 . A formed article, which is produced using the composition according to claim 1 . 13 . The composition according to claim 1 , wherein the thermoplastic resin (C) is an olefin-based resin.
