RESIN-IMPREGNATED FIBER BUNDLE, COMPRESSION MOLDED ARTICLE AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2017/155009

A1

Provided is a resin-impregnated fiber bundle which enables the achievement of a molded article having high surface impact strength. A resin-impregnated fiber bundle which is obtained by impregnating and integrating (A) 100 parts by mass of a bundle of fiber materials with (B) 25-300 parts by mass of a thermoplastic resin, and wherein: the resin-impregnated fiber bundle has a flattened shape that has a cross-sectional shape having a major axis and a minor axis (major axis length > minor axis length) in the width direction; the average major axis length (D1) is 0.5-2.0 mm; the average flatness ratio (D1/D2) as calculated from the average major axis length (D1) and the average minor axis length (D2) is 1.2-8.0; the length (L) of the resin-impregnated fiber bundle is 11-50 mm, and the ratio of the L to the D1 (L/D1) is 10-50; and the bulk density of the resin-impregnated fiber bundle is 0.1-0.4 g/cm3.
