The embodiment of the invention provides a fiber composite material, which is prepared from the following fiber components in percentage by weight: 30 to 90 weight percent of first fiber and 10 to 70 weight percent of second fiber, the first fibers comprise at least 30 wt% of three-dimensional crimped fibers by weight of the first fibers; and a second fiber including a sheath-core composite fiber having a sheath portion and a core portion, the second fiber having a fiber fineness of 1-10 Dtex, and the melting point of the sheath portion being lower than the melting point of the first fiber. The fiber composite material has light mass and good breaking strength, breaking elongation and tearing strength.

    本发明的实施例提供一种纤维复合材料,包括或由下述纤维组分制成:按所述纤维复合材料的重量计,30wt%~90wt%的第一纤维和10wt%~70wt%的第二纤维;所述第一纤维包括按所述第一纤维重量计至少30wt%的三维卷曲纤维;所述第二纤维包含具有皮部和芯部的皮芯型复合纤维,所述第二纤维具有1~10Dtex纤维细度,所述皮部的熔点低于所述第一纤维的熔点。所述纤维复合材料具有较轻的质量与良好的断裂强度、断裂伸长率与撕裂强度。
