Vibration and Wear Characteristics of Aloevera/Flax/Hemp Woven Fiber Epoxy Composite Reinforced with Wire Mesh and BaSO₄

ABSTRACT

These articles presents an experimental investigation on mechanical, vibration, and wear behavior of (aloevera/flax/hemp/wire mesh/BaSO₄) laminated composite. The mechanical characterization was performed with ASTM standard specimens. The free vibration performance was analyzed under two clamping conditions and boundary conditions (clamp-clamp & clamp-free). The wear test trails were accomplished using a pin on disc at different process parameters like sliding speed (3–5 m/s), sliding distance (1000 m) and applied load (10–30 N) under sliding dry environment at room temperature of 28 ± 5^◦C. The scanning electron microscopy was used to examine the interaction between the matrix and reinforcement interface after the failure. The experimental results revealed that the addition of wire mesh and BaSO₄ filler in the fabricated composite Aleovera+Hemp+Wiremesh+Flax+Aleovera+BaSO₄ composite (C4) increased the tensile strength by 8.68% compared to Aleovera+Hemp+Wire mesh+Flax+ Aleovera (C3) composite and it also depicts that the addition of wire mesh and BaSO4 as reinforcement has improved 5.42% of flexural strength compare to Aleovera+Hemp+Flax+Aleovera+BaSO₄ composite (C2). The addition of BaSO₄ improved the hardness in both C2 and C4 composites. The 5% addition of BaSO₄ enhanced the natural frequency of the composites. Among the composites, the C4 has shown the highest coefficient of friction during the experimental trials.

摘要

本文对（aloevera/亚麻/大麻/丝网/BaSO4）层状复合材料的力学、振动和磨损性能进行了实验研究. 力学特性用ASTM标准试样进行. 分析了两种夹持条件和边界条件（夹持-夹持和无夹持）下的自由振动性能. 在室温为28±5℃的滑动干燥环境下，使用销-盘在不同工艺参数（如滑动速度（3-5m/s）、滑动距离（1000m）和施加载荷（10-30N）下完成磨损试验. 使用扫描电子显微镜检查基体和增强体之间的相互作用故障后的接口. 实验结果表明，在制备的复合材料（C4）中加入丝网和BaSO4填料，其拉伸强度比Aleovera+大麻+丝网+亚麻+Aleovera（C3）提高了8.68%，同时说明了钢丝网和BaSO4的加入对复合材料拉伸强度的影响与aleora+大麻+亚麻+aleora+BaSO4复合材料（C2）相比，增强体的抗弯强度提高了5.42%. BaSO4的加入提高了C2和C4复合材料的硬度. 添加5%的BaSO4提高了复合材料的固有频率. 在这些复合材料中，C4在实验中表现出最高的摩擦系数.
