The invention relates to a thermoplastic polyurethane matrix resin composition, comprising (i) at least one bridged and/or fused and/or spiro polycyclic alcohol compound; (ii) at least one polyisocyanate; and (iii) at least one diol, which is different from the at least one bridged and/or fused and/or spiro polycyclic alcohol compound (i). The at least one bridged and/or fused and/or spiro polycyclic alcohol compound (i) is present in the thermoplastic polyurethane matrix resin composition in an amount of at least 10 wt.-% by weight, preferably at least 20 wt.-%, most preferably at least 25 wt.-%. Furthermore, the present invention relates to a fiber-reinforced composite comprising a cured thermoplastic polyurethane polymer matrix according to the present invention and a fiber material. Moreover, a method for the manufacture of the fiber-reinforced composite according to the present invention and use of the composition or the fiber-reinforced composite in railway vehicles, automotive vehicles, aircraft vehicles, boats, space vehicles, motorbikes, bicycles, sporting goods, e.g., skis, snowboards, rackets, golf clubs, fishing rods, baseball bats, hockey sticks, arrows, archery bows, surfboards, javelins, exercise equipment, cell phone and laptop housings, helmets, functional clothing, shoes, construction parts in bridges and buildings or wind turbine blades are described.
本发明涉及一种热塑性聚氨酯基体树脂组合物,该组合物包含:(i) 至少一种桥联和/或融合和/或螺环多环醇类化合物;(ii) 至少一种多异氰酸酯;以及 (iii) 至少一种二元醇,该二元醇不同于至少一种桥联和/或融合和/或螺环多环醇类化合物 (i)。在热塑性聚氨酯基体树脂组合物中,至少一种桥联和/或融合的和/或螺环多环 醇化合物(i)的含量按重量计至少为 10 wt.-%,优选至少 20 wt.-%,最优选至少 25 wt.-%。此外,本发明还涉及一种纤维增强复合材料,该复合材料由根据本发明固化的热塑性聚氨酯聚合物基体和纤维材料组成。此外,本发明还涉及一种纤维增强复合材料的制造方法,以及该组合物或纤维增强复合材料在铁路车辆、汽车车辆、飞机车辆、船只、太空交通工具、摩托车、自行车、体育用品(如滑雪板、滑雪板、球拍)中的应用、描述了滑雪板、滑雪板、球拍、高尔夫球杆、钓鱼竿、棒球棒、曲棍球杆、箭、射箭弓、冲浪板、标枪、运动器材、手机和笔记本电脑外壳、头盔、功能性服装、鞋、桥梁和建筑物中的建筑部件或风力涡轮机叶片。
