The mechanical properties and vibration damping characteristics of cross-ply laminates ([90°/0°/90°] and [0°/90°/0°]), [0°/45°/0°], four-layered angle ply laminate ([90°/0°]s) and Quasi-isotropic laminates ([0°/90°/45°]s, [0°/45°/90°]s,) containing 50 ± 2 wt% of banana fibres in polyester matrix were investigated. The experimental results indicate that the tensile strength, Young’s modulus, impact strength, and the natural frequency were superior for [0°/90°/0°] laminates. In the case of flexural properties, the Quasi-isotropic laminates displayed better performance than the other configurations. Tensile fractured specimens were examined under a scanning electron microscope (SEM) to understand the difference in failure behavior due to the inter-ply orientation in the laminate.

纤维层间取向对香蕉纤维增强聚酯复合层压板机械和自由振动性能的影响
四层交叉层压板([90°/ 0°/ 90°]和[0°/ 90°/ 0°]),[0°/ 45°/ 0°]的机械性能和减振特性角层板层压板([90°/ 0°] s)和准各向同性层压板([0°/ 90°/ 45°] s,[0°/ 45°/ 90°] s研究了在聚酯基体中含有50±2wt%的香蕉纤维的香蕉。实验结果表明,[0°/ 90°/ 0°]层压板的拉伸强度,杨氏模量,冲击强度和固有频率均优异。就弯曲性能而言,准各向同性层压板表现出比其他构型更好的性能。在扫描电子显微镜(SEM)下检查拉伸断裂的样品,以了解由于层压材料中层间取向而导致的破坏行为差异。
