In recent years, the use of natural fibers as reinforcements in polymer composites to replace synthetic fibers like glass is presently receiving increasing attention. Because of their increasing use combined with high demand, the cost of thermosetting resin has increased rapidly over the past decades. However the widely used synthetic fillers such as glass fiber are very expensive compared to natural fibers. Natural fiber-reinforced thermosetting composites are more economized to produce than the original thermosetting. Moreover the use of natural fiber in thermosetting composites is highly beneficial, because the use of natural fibers will be increased. In this study, a bamboo fiber-reinforced thermoplastic composite that made the RTM was evaluated to mechanical properties.
