Abstract

Nonwoven mats from hemp and polypropylene fibers in various proportions were produced and hot pressed to make composite material. The effect of hemp fiber content and anisotropy in the nonwoven mats resulting from the carding technology were examined on the basis of the three-point bending, tensile and impact properties of the resultant composite materials. Because of the hydrophilic nature and poor dimensional stability of cellulosic fibers due to swelling, the effect of water sorption on mechanical performances was also investigated. Optimal mechanical properties were achieved in composites made from 40-50 % of hemp fiber by weight. As was expected, better mechanical properties were found in the specimens cut from the composite sheets parallel to the direction of carding. A large decrease in three-point bending properties was noticed after immersing the composite samples in distilled water for 19 days, whereas the impact strength increased. Double carding of the raw materials resulted in a decreased anisotropy in the composite material.
