这项工作的目的是建立和优化适用于汽车和运输行业应用的热固性香蕉纤维增强复合材料的生产工艺。研究了纤维表面化学改性和处理以及环氧和生态聚酯香蕉纤维复合材料的加工条件。弯曲测试表明，由于纤维/基体相互作用的改善，香蕉纤维/生态聚酯复合材料具有更高的弯曲强度和模量。进行环境测试并评估复合材料吸湿前后的压缩性能。经碱性预处理后，所得香蕉纤维/环氧树脂复合材料的弯曲强度为 34.99 MPa，压缩强度为 122.11 MPa，并具有改善的耐环境暴露性。而非碱预处理的香蕉纤维/聚酯复合材料的弯曲强度为40.16 MPa，压缩强度为123.28 MPa，比相同基体的预处理纤维复合材料具有更高的耐湿热性。
The purpose of this work was to establish and optimize a process for the production of banana fiber reinforced composite materials with a thermoset, suitable for automotive and transportation industry applications. Fiber surface chemical modifications and treatments were studied along with processing conditions for epoxy and eco-polyester banana fiber composites. Flexural tests show that banana fiber/eco-polyester composites have a higher flexural strength and modulus, due to improved fiber/matrix interaction. Environmental tests were conducted and the compressive properties of the composites were evaluated before and after moisture absorption. The resulting banana fiber/epoxy composites were found to yield a flexural strength of 34.99 MPa and compressive strength of 122.11 MPa when alkaline pretreated, with improved environmental exposure resistance. While the non alkaline pretreated banana fiber/polyester composites were found to yield a flexural strength of 40.16 MPa and compressive strength of 123.28 MPa, with higher hygrothermal resistance than pretreated fiber composites with the same matrix.
