Abstract

Composite materials have become increasingly popular and widely used in the present world due to their unique combination of properties that cannot be achieved by any single material. In the current study the mechanical properties of composite laminates (Jute, palm and banana fibers) were fabricated by varying groundnut husk and seashell powders quantities (5, 10, 15 and 20gms) in epoxy resin using hand layup technique. In according to the ASTM standards, a mixture of Epoxy (LY556) and Hardener (araldite) HY951 is used. The ratio of epoxy to hardener is 10:1. The material will be properly mixed for some time before being used to create laminates. Samples were fabricated with different compositions of jute, palm and banana fibers. Tensile, Compression properties of laminates were analyzed by testing composite laminates on universal testing machine. In this context the weight ratio of groundnut husk to seashell powder is 2:1. Analysis states that both the powders have impact on the mechanical properties of laminates. The impact of groundnut husk powder is slightly more on the laminates mechanical properties (tensile, compression) when related to seashell powder.

航空航天和包装领域用复合层压板

复合材料由于其独特的组合性能是任何一种材料都无法达到的，在当今世界得到越来越广泛的应用。在目前的研究中，采用手工铺层技术，将花生壳和贝壳粉末(5、10、15和20克)添加到环氧树脂中，制备了复合材料层压板(黄麻、棕榈和香蕉纤维)的力学性能。根据ASTM标准，使用环氧树脂(LY556)和硬化剂(钠盐)HY951的混合物。环氧树脂与硬化剂的比例为10:1。在用于制造层压板之前，材料将适当混合一段时间。以黄麻、棕榈和香蕉纤维为原料，制备了不同成分的样品。在万能试验机上对复合材料层合板进行了拉伸、压缩性能测试。在这种情况下，花生壳与贝壳粉的重量比为2:1。分析表明，这两种粉末对层压板的力学性能都有影响。花生壳粉对层压板力学性能(拉伸、压缩)的影响在与贝壳粉相关时略大。
