Abstract

In this paper, textile-ramie fiber (RF) reinforced anionic polyamide-6 (APA6) composites were prepared successfully with the heat treated ramie fiber and caprolactam as monomer.The effects of the heat-treatment on the functional groups, the crystallization, the mechanical properties and the fracture morphology of the ramie fiber were studied. Meanwhile, the mechanical properties, thermal stability, as well as interfacial properties of the RF/APA6 composites were also investigated. The results showed that the hydroxyl groups covering on the ramie fiber surface decreased significantly, the crystallinity, the tensile strength and modulus decreased after the 280 ℃ heat-treatment, but no obvious changes in the morphology of the ramie fiber. The interfacial adhesion between the resin and the ramie fiber of the RF/APA6 composites was excellent. Compared with the neat APA6, the tensile strength of the composites increased slightly, while the tensile modulus, flexural property and the thermal stability were increased significantly.
