Abstract

The high specific properties and environmental durability of synthetic fibers make them a popular choice for reinforcing lightweight composites. Unfortunately, they are often limited by their poor biodegradability and high cost. Nevertheless, natural fibers are critical in industrial applications due to their environmental and economic benefits. This study investigated the tensile and flexural behavior of natural hybrid jute/ramie and jute/flax composites with different stacking sequences. A quasi-static punch shear test was also performed to understand their deformation behavior. Jute, ramie, and flax composites have also been fabricated for comparison. Tensile and flexural tests showed a positive hybrid effect in some samples, whereas flax–jute hybrid composites in two different stacking sequences exhibited a synergistic effect. While a maximum improvement of 37.99 % was achieved in the tensile test, this rate was 64.81 % in the flexural test with these hybrid composites. According to punch shear experiments, punch geometry and stacking sequence considerably impact punch shear strength, energy absorption capacity, and deformation.

混合效应对黄麻/拉米和黄麻/亚麻增强混合复合材料的拉伸、弯曲和准静态冲剪行为的影响

合成纤维具有较高的特定性能和环境耐久性，因此成为增强轻质复合材料的热门选择。遗憾的是，它们往往受到生物降解性差和成本高昂的限制。尽管如此，天然纤维因其环境和经济效益，在工业应用中仍然至关重要。本研究调查了不同堆叠顺序的天然混合黄麻/拉米和黄麻/亚麻复合材料的拉伸和弯曲行为。为了了解它们的变形行为，还进行了准静态冲剪试验。此外，还制作了黄麻、苎麻和亚麻复合材料进行比较。拉伸和弯曲测试表明，一些样品具有积极的混合效应，而采用两种不同堆叠顺序的亚麻-黄麻混合复合材料则表现出协同效应。这些混合复合材料在拉伸试验中的最大改进率为 37.99%，而在弯曲试验中的改进率为 64.81%。根据冲压剪切实验，冲压几何形状和堆叠顺序对冲压剪切强度、能量吸收能力和变形有很大影响。
