摘要： The invention describes a new synthetic fiber material of polyhydroxyether, as well as a melt-spinning method for its production. The new material can be used, in particular, for stabilization of the reinforcement fibers of high-performance fiber composite materials before they are embedded in the matrix material. During this usage, the polyhydroxyether fiber material dissolves at a temperature above its glass transition temperature entirely in the matrix material, so that the reinforcement fibers can be arranged largely free of kinking. In addition, it forms cross-links with the matrix material to form a homogeneous matrix and thus does not constitute a disruptive third phase in the composite material. The compatibility of the matrix and reinforcement fiber is also improved. It was possible to improve the bending strength of test slabs by 12% as compared to that of reference slabs with polyester filament.
摘要翻译：本发明描述了一种新的聚羟基醚的合成纤维材料，以及用于其生产的熔体纺丝方法。新材料特别可用于在将高强度纤维复合材料嵌入基质材料之前使其增强纤维稳定化。在这种使用过程中，聚羟基醚纤维材料在高于其玻璃化转变温度的温度下完全溶解在基体材料中，使得增强纤维可以很大程度上没有扭结。此外，它与基体材料形成交联以形成均匀的基质，因此不会在复合材料中构成破坏性的第三相。基体和增强纤维的相容性也得到改善。与具有聚酯长丝的参考板相比，可以将试验板的弯曲强度提高12％。
