Abstract


Tensile and flexural strength of biopolymer polyhydroxyalkanoate reinforced with (20,40%, and 60)wt.% flax fibers were estimated theoretically by using Ansys program version (11) under variation loading. ISO-R-527 and ASTM D790 standards were used to modeling the tensile and flexural test samples respectively by Ansys program. The theoretical data shows that high tensile and flexural strength value for polyhydroxyalkanoate after reinforcing with flax fibers and this strength will increase with increasing weight fracture of fibers. The theoretical results shows that high tensile strength value for polyhydroxyalkanoate after reinforcing with flax fibers due to high elastic modulus for these fibers and this strength will increase with increasing percentage of fibers and this agree with the experimental results obtained from tensile test .
