本文对复合材料在层内和层间混合的准静态拉伸和压缩载荷进行了实验研究。使用T700SC碳和E-CR玻璃纤维开发了新型单向织物形式的一致增强。复合材料采用环氧树脂的树脂传递成型工艺制造，并进行表征，以确保一致性和可比性，进一步以可靠的方式更容易理解和确认混合效应。拉伸失效应变表现为+7.4%的正杂化效应，压缩失效应变表现为6.4%的负杂化效应。3个碳系和3个玻璃系嵌套在一起的密交杂交种力学性能最好；复合材料的抗拉强度和抗压强度分别提高了+17.8%和+39.6%。结果表明，不同的混合策略可以用来平衡复合材料在结构和轻量化应用中的成本和性能。
Experimental studies are presented on quasi-static tensile and compressive loading of composites hybridised at two levels: intraply and interply. Consistent reinforcements in the form of novel unidirectional fabrics were developed using T700SC carbon and E-CR glass fibres. Composites were manufactured using Resin Transfer Moulding process with epoxy resin and characterised to ensure consistency and comparability, further enabling easier understanding and confirmation of hybrid effect in a reliable way. Failure strain in tension for interply hybrid revealed a positive hybrid effect of +7.4%, while interply hybrid showed a negative hybrid effect of 6.4% in compression. Intraply hybrid with three carbon and three glass tows blocked together demonstrated the best mechanical performance among all hybrids; synergistic effects of +17.8% and +39.6% in tensile and compressive strength, respectively, was observed for this hybrid configuration. The results show that different hybridisation strategies can be exploited to balance cost and performance of composites for structural and lightweight applications.
