Processing and properties of natural fiber reinforced semi-finished polymers

抄録

The most common methods of processing natural fibers have been tested in the production of glass-fiber reinforced polymers. This can result in problems due to inadequately adapted process parameters. Therefore the effect of production and treatment of fibers and semi-finished products like hybrid nonwovens and the process parameters on the properties of the part produced were studied. The material technology is available for using natural fibers as reinforcing agents, however, only a few effective products exist. The fiber/matrix interface is of great significance for the quality of the composite material. It can be characterized by means of the IR-spectroscopy, the scanning electron microscopy and by the determination of the mechanical properties. The fiber/matrix interaction can be improved significantly if the natural fibers are purified and alkalized, coupling agents are applied and the manufacturing process of the system natural fiber/thermoplastics is optimized.
