Abstract: 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).

Abstract: A composition improves mechanical strength (e.g., impact resistance and flexural strength), and achieves improved mass productivity by reducing a situation in which a strand fuzzes during extrusion. The composition includes a conjugated diene-based polymer (A), fibers (B), and a thermoplastic resin (C), the composition including the conjugated diene-based polymer (A) in a ratio of 0.05 to 30 parts by mass based on 100 parts by mass of the thermoplastic resin (C), and including the fibers (B) in a ratio of 3 to 150 parts by mass based on 100 parts by mass of the thermoplastic resin (C), wherein the conjugated diene-based polymer (A) includes at least one functional group selected from the group consisting of an alkoxysilyl group and an amino group.
