Abstract

Carbon Fiber Reinforced Thermoplastic (CFRTP) is drawing attention, currently in practical use, to shorten a manufacturing time and to reduce manufacturing cost. Though investigation for utilizing CFRTP is conducted flourishingly, the manufacturing method of CFRTP having enough performance has not been established yet. High viscosity of thermoplastic matrix disturbs good molding. The effective intermediate material is necessary. In this report, we used UD tape (SHINDO, TP CA143) that is slit from poly-amid film impregnated carbon fiber spread tow. We tried to produce CFRTP tube by using hot-press processing prepreg that is braided by these UD tapes. Braided prepreg consists of braiding yarns and axial yarns. Determination of the mechanical properties of a composite structure is essential to be applied in accordance with its requirements. We prepared three kinds of samples with different numbers of axial yarn and bending properties of CFRTP were determined by bending tests. Bending strength was proportional to the number of axial yarn and a small number of axial yarns showed ductile fracture, whereas a large number of axial yarns showed brittle fracture.

轴线插入根数对组绳结构碳纤维强化热塑性树脂管的力学特性产生的效果

碳纤维增强热塑性塑料(CFRTP)在缩短制造时间和降低制造成本方面受到广泛关注，目前已在实际应用中得到广泛应用。尽管对CFRTP利用的研究正在蓬勃进行，但尚未建立起性能足够好的CFRTP的制造方法。热塑性塑料基体的高粘度影响良好的成型。有效的中间材料是必要的。在本报告中，我们使用的UD胶带(SHINDO, TP CA143)是从浸渍碳纤维的聚酰胺薄膜中分离出来的。我们尝试用这些UD带编织的热压加工预浸料来生产CFRTP管。编织预浸料由编织纱和轴向纱组成。确定复合材料结构的力学性能是根据其要求进行应用的必要条件。制备了三种不同轴纱数的CFRTP样品，并通过弯曲试验测定了CFRTP的弯曲性能。抗弯强度与轴纱数成正比，少量轴纱表现为韧性断裂，大量轴纱表现为脆性断裂。
