由包含纤维的复合树脂成形的成形品
摘要：
一种由包含纤维的复合树脂成形的成形品，其含有主剂树脂(1)和纤维长度方向的端部经解纤而得的纤维状填料(2)。将以1～2mm的厚度成形而得的第一板状试验片在‑10℃下保持3小时后，使250g的重物下落时未被破坏的最大高度记作H，并将从仅主剂树脂的成形部件以1～2mm的厚度成形而得的第二板状试验片在‑10℃下保持3小时后，使250g的重物下落时未被破坏的最大高度记作Ho时，满足Ho×0.4≤H≤Ho。将成形品的夏比冲击强度记作S(JIS K7111)，并将仅主剂树脂的成形部件的夏比冲击强度记作So时，满足So×0.4≤S≤So。其结果，能够实现高弹性模量，并且能够实现对于表面方向的冲击和单一方向的冲击这两者的高耐冲击性。
摘要（英）：

A molded article of composite resin containing fibers includes base resin (1) and a fibrous filler (2) having fibrillated ends in a fiber length direction. An expression Ho*0.4<=H<=Ho is satisfied, where H is a maximum height for an unbroken first plate-like test piece having a thickness of 1 to 2 mm after the test piece is kept at -10 degree centigrade for three hours and then is hit by a droppedweight of 250g; and Ho is a maximum height for an unbroken second plate-like test piece only made of the base resin with a thickness of 1 to 2 mm after the test piece is kept at -10 degree centigradefor three hours and then is hit by a dropped weight of 250g. An expression So*0.4<=S<=So is satisfied, where S is a Charpy impact strength (JIS K7111) of the molded article, and So is a Charpy impactstrength of the molded article only made of the base resin. This can obtain a high modulus of elasticity and high resistance to surface impact strength and impact strength in one direction.
