Processing and Characteristics of Novel Henequen Fiber Reinforced Polyamide 6 Composites: Effects of Feeding Route and Surface Treatment of Natural Fiber
In the present study, novel natural fiber composites consisting of untreated and alkali-treated chopped henequen fiber and polyamide 6 (PA6) were produced by hopper-feeding and side-feeding upon extrusion, respectively, and consecutively by injection molding. As a preliminary study, the effects of fiber feeding route and alkali-treatment on the thermal and mechanical characteristics of henequen fiber/PA6 composites are investigated. The characteristics are compared with neat PA6. The results inform that, upon extrusion process, side-feeding is more favorable than hopper-feeing in order to increase the heat deflection temperature, tensile, flexural, and impact properties of henequen fiber/PA6 composites and the alkali-treatment is further increased the properties. The study provides some preliminary results on the processing and properties of novel composites with agave plant-derived natural fiber and an engineering plastic and also there are more experimental margins to increase the mechanical and thermal properties by process manipulation.
