Abstract

Polyvinyl-chloride (PVC) is inexpensive, durable, and flexible thermoplastic material. PVC is one of the most versatile thermoplastics, and plays an important role in the plastic industry. This paper investigated the mechanical properties of reinforcing PVC by hemp fibers. Hemp fibers were added at different weight fractions (4.46%, 6.2%, 7.75%, 9%, and 11% wt). Influence of fiber's content on composite tensile strength and strain were revealed and the results showed that, at 6.2% wt the tensile strength of PVC 75, PVC 55 with hemp fiber composites was improved by 34.93% and 54.8% respectively. At 6.2% wt, the fibers were longitudinally, at 45°, horizontally, and randomly oriented. The influences of fiber's orientation on both stress and strain of the composites were studied and the results showed that, when the fibers were longitudinally oriented, the tensile strength of the composites was higher than that of the other fiber's orientation. Also, the tensile strength of the composites at 6.2% wt was highly improved, when the fibers were weaved. The effect of hemp fiber on the hardness of PVC was deliberated.
