Abstract
The effect of fiber length and fiber volume fraction at different crosshead speeds on the mechanical properties and toughness of randomly oriented glass fibers reinforced polyurethane elastomer composites were studied using standard simple tension test. The modulus of elasticity and the yield stress increase with increasing the fiber volume fraction, the fiber length and the crosshead speed. The percentage increase due to the increasing of fiber volume fraction for 10 mm fiber length is much higher than that for 5 mm fiber length, while the percentage increase due to increasing of the crosshead speed for 10 mm fiber length is lower than that for 5 mm. The toughness of the failed specimens decreases with increasing the fiber volume fraction, the crosshead speed and fiber length.
