Experimental Investigation on the Mechanical Properties of Green Hybrid Sisal and Glass Fiber Reinforced Polymer Composites

ABSTRAT

Composites made from renewable sources have become important alternative materials for designing and manufacturing engineering and industrial products. Natural fiber composites have become superior materials compared to conventional fiber composites, due to their easy manufacturing process, high-fiber content, reduction in the polluting base content, lightweight, and incineration. Environmental cleanliness is an increasing concern to look for sustainable alternative materials that can replace conventional materials that are being used now. Natural fibers constitute a good alternative reinforcement material, since they are readily available in fibrous form, and can be extracted at very low costs. In the present study, environment friendly green composites have been prepared and the mechanical properties of these composites are evaluated. The results indicated a significant improvement in the tensile, flexural, and impact properties of the hybrid composites, and the effect of hybridization reduces the environmental effects. The internal structure of the broken surface, delamination of fibers, and the failure morphology are analyzed using the scanning electron microscopy analysis.

实验研究绿色混合剑麻纤维和玻璃纤维增强聚合物复合材料的机械性能

来自可再生能源制成的复合材料已经成为设计和制造工程和工业产品的重要替代材料。天然纤维复合材料已成为优良的材料，相对于传统的纤维复合材料，由于其简单的制造工艺，高纤维含量，减少污染基含量，重量轻，和焚烧。环境洁净的关注度，使越来越多的以寻找能取代现在正在使用的常规材料可持续的替代材料。天然纤维是一种很好的替代增强材料，因为它们容易在纤维状的形式，并且可以在非常低的成本提取。在本研究中，环境友好的绿色复合材料的制备和这些复合材料的机械性能进行了评价。结果表明在拉伸，弯曲显著改进，以及混杂复合的效果减少了对环境的影响。使用扫描电子显微镜分析来分析破碎表面，纤维的脱层，以及未能形态的内部结构。
