Tensile, flexural, impact, and hardness properties of alkaline-treated Sunnhemp fiber reinforced polyester composites

ABSTRACT

The natural fibers and their specific properties attracted researchers in the recent years for the development of new polymer composites. In this way, the Crotalaria juncea L. (Sunnhemp) fiber was identified as a potential material for reinforcement and the preparation of polyester-based polymer matrix composites was carried out. The present investigation was focused on fabrication of untreated and alkaline-treated C. juncea L. (Sunnhemp)–polyester composite laminates and the evaluation of tensile, flexural, impact, and hardness properties as per ASTM. The different kinds of fiber orientations such as random, continuous, biaxial, and triaxial were considered and the properties were evaluated.

摘要

近年来，天然纤维及其独特的性能吸引了新的聚合物复合材料的研究者。通过这种方法，将野百合（Sunt线虫Junca L）（SunnHiMP）纤维作为一种潜在的增强材料，并进行了聚酯基聚合物基复合材料的制备。本研究的重点是未经处理和碱性处理的猪屎豆（SunnHAMP）-聚酯复合材料层合板的制备，并根据ASTM对拉伸、弯曲、冲击和硬度性能进行评价。考虑了不同的纤维取向，如随机、连续、双轴和三轴，并对其性能进行了评价。
