Abstract

Carbon fiber reinforced plastics (CFRP) are attracting attention in the automotive industry due to their light weight. Thermoset plastics like epoxies are mainly used as matrices of CFRP in that industry. The curing time of the thermosetting resin is long thus leading to poor productivity. Within thermoplastic resins, polycarbonate (PC) is excellent for its impact properties; consequently, it is expected to be used as the matrix of composite materials for automotive structures. Moreover, in order to obtain outstanding strength, the application of continuous fibers as reinforcement is anticipated. However, large-scale equipment is needed and the work of press load is required in order to impregnate PC into continuous fibers. Recently, unidirectional (UD) tapes of CF/PC in which the PC matrix was impregnated into a CF bundle have been developed. In this study, carbon fiber reinforced polycarbonate (CF/PC) was moulded using UD tapes and the practicality of UD tape was examined by studying its mechanical properties aiming at shortening the moulding time.

碳纤维增强聚碳酸酯的单向胶带成型

碳纤维增强塑料(CFRP)因其重量轻而受到汽车行业的关注。环氧树脂等热固性塑料在该行业中主要用作CFRP的基体。热固性树脂固化时间长，导致生产效率差。在热塑性树脂中，聚碳酸酯(PC)的冲击性能优异;因此，它有望用作汽车结构复合材料的基体。此外，为了获得优异的强度，可以期待连续纤维作为增强材料的应用。然而，要使PC浸渍成连续纤维，需要大型设备和压力负荷的工作。近年来，在CF束中浸渍PC基体的CF/PC单向(UD)带已被开发出来。本研究采用UD胶带对碳纤维增强聚碳酸酯(CF/PC)进行了成型，并通过研究UD胶带的力学性能来验证UD胶带的实用性，旨在缩短成型时间。
