许多研究人员对用天然纤维增强商品热塑性塑料表现出兴趣。然而，天然纤维的缺点是热加工温度低，大约在200℃左右。在本研究中，我们试图通过使用柔性环氧树脂表面涂层来提高天然纤维的热稳定性，从而促进与工程热塑性塑料的加工。采用压缩模压法制备了黄麻织物和聚酰胺6 （PA6）复合材料。采用热重分析（TGA）对黄麻织物的热分解特性进行了评价。对复合材料的拉伸试验和三点弯曲试验进行了力学分析。结果表明，柔性环氧树脂涂层可提高黄麻织物的耐热降解性能。此外，弯曲模量随治疗浓度的增加而提高。涂布和未涂布的黄麻/PA6复合材料的抛光截面的显微照片清楚地表明环氧树脂与PA6之间的界面相互作用。
Many researchers have shown interest in the reinforcement of commodity thermoplastic with natural fibers. However, the drawback of natural fibers is their low thermal processing temperatures, that border around 200℃. In this investigation, we tried to improve the thermal stability of natural fibers with the use of flexible epoxy surface coating that could facilitate processing with engineering thermoplastics. Jute fabric and Polyamide 6 (PA6) composites were prepared by compression molding. The thermal decomposition characteristics of the jute fabric were evaluated by using thermo gravimetric analysis (TGA). Mechanical analysis was conducted to evaluate tensile test and three point bending test of composite. It was found that thermal degradation resistance of jute fabric was improved by coating with flexible epoxy resin. Moreover, the flexural modulus improved with increasing curative concentration. The interfacial interaction between the epoxy and PA6 was clearly indicated by the photo micrographs of the polished cross sections of the coated and uncoated jute fabric/PA6 composites.
