|This study was investigated to evaluate improvements in the tensile properties of self-cure acrylic resin reinforced with siwak fiber and bamboo fibers which were cut into 2, 6, and 12 mm lengths and used at three different concentrations of (3, 6 and 9 wt.%). The mixture of resin and fiber were cured at 2.5 bar and 55ºC in a water bath for 30 min. The cured resin specimen tested for tensile properties (tensile strength, modulus of elasticity, elongation percentage at break) following the methods of ASTM Specification No. 638. The results illustrated that the tensile strength and modulus of elasticity tended to be improved with fiber length and concentration, the largest values of tensile strength and modulus of elasticity for specimens reinforced with bamboo fibers are ( 72.4 MPa and 5.208 GPa) while for specimens reinforced with siwak fibers are (71 MPa and 4.9 GPa) at optimum condition of weight fraction ( 9% ) and fiber length (12 mm), which was significantly higher than other formulations.|
