Abstract

The application of thermoplastic composites (TPCs) in aircraft construction is growing. This paper presents a study of the effect of an applied methodology (standards) on out-of-plane interlaminar strength characterization. Additionally, the mechanical behaviour of three carbon fibre-reinforced thermoplastic composites was compared using the curved beam strength test. Data evaluated using different standards gave statistically significantly different results. The study also showed that the relatively new polyaryletherketone (PAEK) composite had significantly better performance than the older and commonly used polyphenylensulfid (PPS) and polyetheretherketone (PEEK). Furthermore, considering the lower processing temperature of PAEK than PEEK, the former material has good potential to be used in serial aerospace production.

摘要

热塑性复合材料(TPCs)在飞机制造中的应用正在不断增加。本文介绍了一种应用方法(标准)对平面外层间强度表征影响的研究。此外,使用曲梁强度试验比较了三种碳纤维增强热塑性复合材料的力学行为。使用不同标准评估的数据给出了具有统计学显著差异的结果。该研究还表明,相对较新的聚芳醚酮(PAEK)复合材料的性能明显优于较旧且常用的聚苯硫醚(PPS)和聚醚醚酮(PEEK)。此外,考虑到PAEK的加工温度低于PEEK,前一种材料在航空航天批量生产中具有良好的应用潜力。
