Abstract

Abstract This study investigates the mechanical properties of hybrid composites composed of web kapok fibers and fiberglass reinforced with epoxy for potential application in the marine industry. The web kapok fibers were carefully processed using a carding technique to ensure better alignment and consistency. Various composite configurations were produced, and extensive mechanical testing was conducted, including flexural, tensile, and impact tests. The results revealed that the presence of two web kapok fiber layers within the composite significantly increased flexural strength and flexural modulus compared to pure fiberglass laminates. However, a single layer of web kapok fabrics exhibited the highest tensile strength, although it decreased with additional layers. The impact strength of these hybrid composites also showed promising results, especially when compared to raw fiberglass composites. Moreover, these composites exhibited improved resistance to water absorption and corrosion, making them potentially suitable for marine applications. This research highlights the potential of web kapok/fiberglass hybrid composites as an eco-friendly alternative for marine engineering, with implications for reduced environmental impact and sustainable technology in the industry.

用于海洋结构的腹板木棉/玻璃纤维-环氧混合复合材料的力学性能

摘要本研究探讨了由木棉纤维和环氧树脂增强玻璃纤维组成的混合复合材料的机械性能，这些复合材料有望应用于船舶工业。采用梳理技术对木棉纤维进行了仔细加工，以确保更好的排列和一致性。生产了各种复合材料配置，并进行了广泛的机械测试，包括弯曲、拉伸和冲击测试。结果表明，与纯玻璃纤维层压板相比，复合材料中含有两层木棉纤维可显著提高抗弯强度和抗弯模量。不过，单层木棉纤维的拉伸强度最高，但随着层数的增加，拉伸强度有所下降。这些混合复合材料的冲击强度也显示出良好的效果，尤其是与未加工的玻璃纤维复合材料相比。此外，这些复合材料的吸水性和耐腐蚀性也有所改善，因此可能适用于海洋应用。这项研究凸显了腹板木棉/玻璃纤维混合复合材料作为海洋工程环保替代材料的潜力，对减少环境影响和该行业的可持续技术具有重要意义。

期刊介绍： Pure and Applied Chemistry is the official monthly Journal of IUPAC, with responsibility for publishing works arising from those international scientific events and projects that are sponsored and undertaken by the Union. The policy is to publish highly topical and credible works at the forefront of all aspects of pure and applied chemistry, and the attendant goal is to promote widespread acceptance of the Journal as an authoritative and indispensable holding in academic and institutional libraries.
