Effect of fiber type on mechanical properties of polyurethane composites

The effects of three different types of fibers (E-glass, S-glass and Carbon fibers) on physical and mechanical properties of polyurethane resin based composites were studied. The mechanical properties (tensile strength and modulus, flexural strength and modulus, and interlaminar shear strength) of the polyurethane composites were found to depend primarily on the type of fiber, and specifically on the accessibility of hydroxy functionality on the fiber. The results showed that carbon fiber reinforced polyurethane composite had superior properties compared to E-glass and S-glass reinforced composites and the lowest void fraction.
