樹脂含浸繊維束、圧縮成形品およびその製造方法
Document Type and Number:
Japanese Patent JP6739210
Kind Code:
B2
Abstract:
To provide a resin-impregnated fiber bundle that can provide a molded article with a high surface impact strength. A resin-impregnated fiber bundle prepared by impregnating and integrating 100 parts by mass of a bundle of a fiber material (A) with 25 to 300 parts by mass of a thermoplastic resin (B), wherein:
the resin-impregnated fiber bundle has a flattened shape with a lateral cross-sectional shape having a major axis and a minor axis (length of the major axis > length of the minor axis);
an average length (D1) of the major axis is 0.5 to 2.0 mm;
an average flatness ratio (D1/D2) determined from the average length (D1) of the major axis and an average length (D2) of the minor axis is 1.2 to 8.0;
the resin-impregnated fiber bundle has a length (L) of 11 to 50 mm and a ratio (L/D1) between L and D1 is 10 to 50; and
a bulk density is 0.1 to 0.4 g/cm 3 .
