Abstract

Three forms of hemp fiber (untreated, treated with sodium hydroxide solution and treated with sodium hydroxide solution followed by three-aminopropyltriethoxysilane) reinforced polypropylene composites were prepared. The effects of chemical treatments on tensile properties of the composites were studied. The results show that alkali treatment followed by three-aminopropyltriethoxysilane treatment significantly improves the tensile properties. In particular, the specific tensile strengths of alkali-silane treated composites with 30% fiber content are only 4% lower than those of composites reinforced with glass fiber. Scanning electron microscopy examination shows that the improvements in tensile properties can be attributed to better bonding between the fiber and matrix.
