摘要:
The purpose of the present invention is to obtain a fiber-reinforced composite material molded article having high adhesive strength in a boundary portion between an insert portion comprising a fiber-reinforced resin substrate and an integrally molded portion molded integrally with the insert portion. A fiber-reinforced composite material molded article (1) containing reinforcing fibers and a thermoplastic resin and being provided with a first layer (23), a second layer (22), and a third layer (21) in this order, the thickness of each layer, the ratio of the total volume of reinforcing fibers (x2) having a fiber length of 3 mm to less than 100 mm with respect to the total volume of reinforcing fibers present in the layer, the ratio of the total volume of reinforcing fibers (y2) having a fiber length of 0.02 mm to less than 3 mm with respect to the total volume of reinforcing fibers present in the layer, and the volume content of fibers in each layer being controlled so as to be in specific ranges.
摘要(中):
本发明的目的是获得一种纤维增强复合材料成型品,该纤维增强复合材料成型品在包含纤维增强树脂基材的插入部分与与插入部分一体成型的一体成型部分之间的边界部分中具有高粘合强度。 一种纤维增强复合材料成型体(1),其含有增强纤维和热塑性树脂,依次具有第一层(23),第二层(22)和第三层(21),厚度 各层中的纤维长度为3mm至小于100mm的增强纤维的总体积(x2)相对于该层中存在的增强纤维的总体积的比率,增强纤维的总体积 (y2)相对于存在于该层中的增强纤维的总体积具有0.02mm至小于3mm的纤维长度,并且每层中的纤维的体积含量被控制在特定范围内。
