Özet

The objective of this study was to evaluate tensile strength of experimental material made from combinations of polylactic acid (PLA), thermoplastic urethane (TPU) and bamboo (Phyllostachys edulis). Two type of composites were prepared for the test to compare tensile performances of both. Composites were made having 50 % PLA and 50 % TPU in addition to these sample with the content of polymers added 15 % bamboo fibers by weight. Based on the results the composites produced from bamboo-PLA-TPU materials had an average tensile strength value of 8.71 MPa while the composite produced from only PLA and TPU had 9.006 MPa as a corresponding value. The difference between both average values were not significant. Conversely, the Young’s modulus of the bamboo-reinforced composite reached 1700 MPa, while the composite composed only of PLA and TPU exhibited a modulus of 450 MPa.The loading time along with the displacement values of the 100 % polymer based samples results in higher values than those of the samples having bamboo due to higher rigidity.
