Study of Hybridization Effect of New Developed Rice Straw mat/ Glass Fiber Reinforced Polyester Composite

ABSTRACT

Rice comes in the second rank in the world’s major cereal harvest. However, few studies investigate the effect of addition of rice straw as reinforcement to the polymer. In this study, a new mat of random rice straw fiber was developed to ensure a good distribution of rice straw. These rice straw mats were used as reinforcements to polyester. Besides, hybrid composites were manufactured from polyester reinforced with rice straw fiber mat as a natural fiber and glass fiber as synthetic fiber. Six different stacking sequences were made by alternating random glass fiber layers having different areal densities with four layers of the developed rice straw fiber mats. Tensile, flexural, shear, impact and water absorption properties of these hybrid composites were investigated. Generally, the mechanical properties of the composites are improved due to the addition of the glass fibers to the rice straw reinforcements that displays the positive effect of hybridization. The morphology of the fracture surfaces was investigated by scanning electron microscopy.

摘要

水稻在世界主要谷物收成中排名第二然而，很少有研究探讨稻草对聚合物的增强作用为了保证稻草的均匀分布，本研究开发了一种新型的稻草纤维无规毡这些稻草垫被用作聚酯纤维的增强材料以稻草纤维毡为天然纤维，玻璃纤维为合成纤维，聚酯为增强材料，制备了杂化复合材料将不同面密度的无规玻璃纤维层与四层已开发的稻草纤维毡交替铺层，得到六种不同的铺层顺序研究了复合材料的拉伸、弯曲、剪切、冲击和吸水性能在稻草增强体中加入玻璃纤维，可以提高复合材料的力学性能用扫描电镜观察了断口形貌.
