Abstract
This work aims to evaluate the mechanical behavior of the composite of polyurethane (PU) derived from a blend of vegetable oils with reinforcement of cotton fiber (CF) fabrics and added Alumina Trihydrate (ATH). For comparison and study, tests were performed for characterization of the pure PU, PU doped with different ATH contents (10%, 20% and 30%), of PU composite reinforced with cotton fiber and the PU composite reinforced with cotton fiber and ATH. The fibers were oriented at 0 °, ± 45 ° and 90 °. The mechanical properties obtained according to the tensile test for the laminated PU composite reinforced with cotton fiber and doped with 30% of ATH presented an elasticity modulus of 4.733 GPa and ultimate tensile strength of approximately 60 MPa for the samples oriented at 0°. The pure PU exhibited an elasticity modulus of 1.703 GPa and ultimate tensile strength of 39.715 MPa. When comparing the composite results with the pure polyurethane matrix, a significant stiffness and mechanical resistance enhancement was obtained.
