Notes:
Natural fiber reinforced polypropylene composites (NF/PP) have attracted a lot ofattention because of their light weight, good mechanical properties, recyclable and environmentalfriendly features. This work has successfully fabricated ramie fiber reinforced polypropylenecomposites (RF/PP) with a hybrid method of melt-blending and injection molding. Different RF/PPeco-materials have been fabricated by varying the fiber length, fiber content and way of fiberpre-treatment. This paper studied the mechanical properties of the fabricated RF/PP composites indepth by investigating the mechanical behaviors of RF/PP and microstructures of the rupturedsurfaces. The results show that the increases of fiber length and fiber content can improve thetensile strength, flexural strength and compression strength apparently, but result in negativeinfluences on the impact strength and elongation behaviors of RF/PP composites. The optimaladdition amount of ramie fiber is around 20 wt%. The pre-treatment of ramie fiber in 10%~15%NaOH is good to the mechanical properties of RF/PP. The fiber length can be varied in the range of3-8 mm. It is expected that the fabricated RF/PP composites can be applied to automobile industryas environmental friendly eco-materials
