Abstract

The objective of this work is to carry out a comparison of different materials in the form of a bidirectional carbon fabric and hybrid Kevlar and glass as reinforcements in an epoxy matrix with a loading rate of 30wt%. Two experimental tests have been carried out in order to determine the mechanical properties, such as tensile and Brinell hardness tests. In the case of tensile and Brinell hardness tests, the characterization was performed on two types of composite plates reinforced with Woven Carbon Fiber and Hybrid Woven Kevlar and E-Glass with Epoxy (WCF-HWKG/EPOXY) and Hybrid Woven Kevlar and E-Glass with Epoxy (HWKG/EPOXY). Consequently, it has been observed that the tensile and hardness properties of the hybrid composite material (HWKG/EPOXY) are respectively 36% and 46.43% lower compared to (WCF-HWKG/EPOXY). Based on these findings, the studied materials demonstrate potential applications across various fields, including aeronautics, aerospace, and high-performance automotive sectors.

双向编织碳纤维织物和混合凯夫拉尔/玻璃纤维增强的新型环氧树脂复合材料力学性能对比研究

这项工作的目的是对环氧树脂基体中双向碳纤维织物和混合凯夫拉纤维与玻璃纤维作为增强材料的不同材料进行比较，环氧树脂基体的负载率为 30wt%。为了确定材料的机械性能，我们进行了两项实验测试，如拉伸和布氏硬度测试。在拉伸和布氏硬度测试中，对两种类型的复合材料板进行了表征，一种是用碳纤维编织物和凯夫拉纤维编织物以及环氧树脂混合玻璃纤维增强的复合材料板（WCF-HWKG/EPOXY），另一种是用环氧树脂混合凯夫拉纤维编织物以及环氧树脂混合玻璃纤维增强的复合材料板（HWKG/EPOXY）。结果发现，混合复合材料（HWKG/EPOXY）的拉伸性能和硬度分别比（WCF-HWKG/EPOXY）低 36% 和 46.43%。基于这些研究结果，所研究的材料在航空、航天和高性能汽车等各个领域都具有潜在的应用前景。
