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were enhanced by 52.10%, 18.78%, and 166.60%, respectively, when the outermost pineapple leaf fiber layers were superseded with ramie fabric.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.
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。苎麻和菠萝叶纤维因其卓越的材料性能而成为引人关注的天然纤维。本研究旨在揭示在聚合物复合材料中使两种木质纤维素植物纤维织物混杂的可行性。在这项工作中，借助热压技术制备了混杂复合材料。对苎麻和菠萝叶纤维织物增强聚丙烯混杂复合材料的力学性能、吸水性和厚度膨胀性能进行了测定。对非混杂复合材料和混杂复合材料进行了比较，以证明混杂效果。根据研究结果，混杂复合材料，尤其是那些以苎麻纤维作为表层的复合材料，其机械强度有显著提高。与非混杂的菠萝叶织物增强复合材料相比，当最外层的菠萝叶纤维层被苎麻织物取代时，拉伸强度、弯曲强度和夏比冲击强度分别提高了52.10%、18.78%和166.60%。然而，增加菠萝叶纤维含量会降低混杂复合材料的吸水性和厚度膨胀。不可否认，这些研究结果凸显了混杂复合材料在兼具环保特性的同时，实现机械性能和吸水性平衡的潜力。
