Abstract：
Fiber-reinforced composites are among the recognized competing materials in various engineering applications. Ramie and pineapple leaf fibers are fascinating natural fibers due to their remarkable material properties. This research study aims to unveil the viability of hybridizing two kinds of lignocellulosic plant fiber fabrics in polymer composites. In this work, the hybrid composites were prepared with the aid of the hot compression technique. The mechanical, water-absorbing, and thickness swelling properties of ramie and pineapple leaf fiber fabric-reinforced polypropylene hybrid composites were identified. A comparison was made between non-hybrid and hybrid composites to demonstrate the hybridization effect. According to the findings, hybrid composites, particularly those containing ramie fiber as a skin layer, showed a prominent increase in mechanical strength. In comparison with non-hybrid pineapple leaf fabric-reinforced composites, the tensile, flexural, and Charpy impact strengths were enhanced by 52.10%, 18.78%, and 166.60%, respectively, when the outermost pineapple leaf fiber layers were superseded with ramie fabric. However, increasing the pineapple leaf fiber content reduced the water absorption and thickness swelling of the hybrid composites. Undeniably, these findings highlight the potential of hybrid composites to reach a balance in mechanical properties and water absorption while possessing eco-friendly characteristics.
摘要：
纤维增强复合材料是各种工程应用中公认的竞争材料之一。苎麻和菠萝叶纤维由于其卓越的材料特性而成为迷人的天然纤维。本研究旨在揭示两种木质纤维素植物纤维织物在聚合物复合材料中杂交的可行性。在这项工作中,借助热压缩技术制备了杂化复合材料。机械的,吸水,并确定了苎麻和菠萝叶纤维织物增强聚丙烯杂化复合材料的厚度溶胀性能。在非杂交和杂交复合材料之间进行比较以证明杂交效果。根据调查结果,混合复合材料，特别是那些含有苎麻纤维作为表层的，显示机械强度显著增加。与非混合菠萝叶织物增强复合材料相比，拉伸，弯曲,夏比冲击强度提高了52.10%，18.78%,和166.60%，分别,当最外面的菠萝叶纤维层被苎麻织物取代时。然而,增加菠萝叶纤维含量降低了混杂复合材料的吸水率和厚度溶胀。不可否认,这些发现强调了混合复合材料在机械性能和吸水性方面达到平衡的潜力，同时具有生态友好的特性。
