    • The present invention relates to a composite material for a transporting means including a polypropylene-based resin and a carbon long fiber. More specifically, the present invention relates to a fiber-reinforced composite material composition for a transporting means comprising: 40-90 wt% of a polypropylene-based resin; 5-60 wt% of a carbon long fiber having a fiber diameter of 1-50 μm and a weight average fiber length of 20-150 mm; and 0.3-15 wt% of a compatibilizer, wherein the compatibilizer includes one selected from the group consisting of an ionomer, a propylene-polar monomer copolymer, a denaturalized water-added polymer, and combinations thereof. The composite material has improved interface properties between a polypropylene-based resin and a carbon long fiber because a particular compatibilizer is used so that the strength and shock resistance of the composite material are improved. The composite material also has excellent heat resistance so as to be applied not only to various sorts of transporting means including cars but also various fields requiring the fiber-reinforced composite material.
    • 本发明涉及一种用于输送装置的复合材料,其包括聚丙烯基树脂和碳长纤维。 更具体地,本发明涉及一种用于输送装置的纤维增强复合材料组合物,其包含:40-90重量%的聚丙烯基树脂; 5-60重量%的纤维直径为1-50微米,重均纤维长度为20-150毫米的碳长纤维; 和0.3-15重量%的增容剂,其中增容剂包括选自离聚物,丙烯 - 极性单体共聚物,变性水加成聚合物及其组合中的一种。 复合材料具有改善的聚丙烯类树脂与碳长纤维之间的界面性能,因为使用特定的增容剂以提高复合材料的强度和抗冲击性。 复合材料也具有优异的耐热性,不仅可以应用于各种包括汽车的输送装置,而且可以应用于需要纤维增强复合材料的各种领域。
