Abstract

FRTP is highly recyclable and suitable for mass production. In addition, by using the spread yarns treated in a wide and thin state as the woven structure, it is expected that the generation of voids at the time of impregnation will be reduced and the mechanical properties will be improved, and the impregnation time will be shortened. In this study, the effect of ply thickness on a damage development behavior of woven CFRTP using spread yarns was investigated by FEM based on damage mechanics. Firstly, finite element models of the woven structure with different ply thickness changed from the conventional yarns to the spread yarns were created. Secondary, as the material properties of the model, that of the UD material were applied to the fiber bundle, and the material nonlinear model based on stress dependence of the thermoplastic resin was applied to the matrix. Finally, damage development analysis was carried out on those models. As a result, it was clarified that the damage development behavior in the fiber bundle and in the matrix differs depending on the ply thickness.

铺层厚度对伸展纱热塑性机织复合材料损伤发展行为的影响

FRTP可回收性强，适合批量生产。此外，采用宽细状态处理的铺展纱作为织造结构，有望减少浸渍时空隙的产生，提高机械性能，缩短浸渍时间。采用基于损伤力学的有限元方法，研究了铺层厚度对CFRTP织物损伤发展行为的影响。首先，建立了由常规纱改为铺展纱不同粗细编织结构的有限元模型;其次，作为模型的材料性质，将UD材料的材料性质应用于纤维束，将基于热塑性树脂应力依赖性的材料非线性模型应用于基体。最后，对这些模型进行了损伤发展分析。结果表明，纤维束和基体中的损伤发展行为随厚度的不同而不同。
