Abstract

Tensile tests were carried out on carbon fiber high-entropy alloy, carbon fiber aluminum alloy, carbon fiber titanium alloy, and carbon fiber-reinforced composite laminates. Their mechanical properties were investigated at the tensile strain rates of 3·10^–3, 1·10^–3, and 1·10^–4 s^–1. Compression tests on carbon fiber high entropy alloy (HEA) and carbon fiber-reinforced composite laminates were carried out at the strain rates of 3·10^–3 and 1·10^–3 s^–1, respectively. Results showed that the carbon fiber high-entropy alloy composite laminate was more elastic than the carbon fiber-reinforced composite laminate at the strain rates of 3·10^–3, 1·10^–1, and 1·10^–4 s^–1. Their strength increased by 27, 16, and 10%, and the breaking strength by 18, 12, and 14%, respectively. Compared with the carbon fiber-reinforced composite laminate, the compressive strength of the carbon fiber HEA composite laminate increased by 44 and 29% at the compressive strain rates of 3·10^–3 and 1·10^–3s^–1, respectively.

碳纤维高熵合金复合材料层压板的拉伸和压缩性能分析

对碳纤维高熵合金、碳纤维铝合金、碳纤维钛合金和碳纤维增强复合材料层压板进行了拉伸试验。在拉伸应变速率为 3-10-3、1-10-3 和 1-10-4 s-1 时，对它们的机械性能进行了研究。在应变速率分别为 3-10-3 和 1-10-3 s-1 时，对碳纤维高熵合金（HEA）和碳纤维增强复合材料层压板进行了压缩试验。结果表明，在应变速率为 3-10-3、1-10-1 和 1-10-4 s-1 时，碳纤维高熵合金复合材料层压板比碳纤维增强复合材料层压板更具弹性。它们的强度分别提高了 27%、16% 和 10%，断裂强度分别提高了 18%、12% 和 14%。与碳纤维增强复合材料层压板相比，在压缩应变率为 3-10-3 和 1-10-3s-1 时，碳纤维 HEA 复合材料层压板的抗压强度分别提高了 44% 和 29%。
