Sliding wear, mechanical, flammability, and water intake properties of banana short fiber/Al(OH)₃/epoxy composites

ABSTRACT

Banana short fiber/Al(OH)₃/epoxy composite laminates were prepared by dispersing short banana fiber and Al(OH)₃ particulates in an epoxy matrix and investigated for their specific wear rate, water intake, flammability and mechanical properties. The sliding wear results showed that due to the synergistic effect of both fiber and filler in epoxy matrix enhanced the wear resistant in the composites. Similarly, the tensile stress and hardness improved significantly due to the addition of banana fiber in the composite material. Also, it is found that the composite becomes more fire resistant due to the addition of Al(OH)₃. However, the higher percentage of fiber and filler increases the water absorption rate due to voids in the composite. The results of this study provide the insights of solid–solid interface leading to different bulk properties.

通过将短香蕉纤维和Al（OH）3颗粒分散在环氧基体中，制备了香蕉短纤维/ Al（OH）3／环氧复合材料层板，并研究了它们的比磨损率、吸水率、易燃性和力学性能。滑动磨损结果表明，由于纤维和填料在环氧基体中的协同作用，增强了复合材料的耐磨性。类似地，由于在复合材料中加入香蕉纤维，拉伸应力和硬度显著提高。此外，发现由于Al（OH）3的加入，复合材料变得更耐火。然而，纤维和填料的较高百分比增加了复合材料中空隙引起的吸水率。这项研究的结果提供了固体固体界面的见解导致不同的块状性质。
