Optimization of Parameters in Fiber Reinforced Polyurethane Composited Reaction Injection Molding

Abstract:

In order to explore effects of various processing parameters on the mechanical properties of jute fiber reinforced polyurethane foam composites, jute fiber reinforced polyurethane composites were prepared by variable fiber reinforced reaction injection technology. The influence of jute fiber contents, fiber length, mold pressure and fiber modification treatment to the impact toughness was analyzed by orthogonal test in this paper. The microstructure and fracture micrograph of impact fracture specimens were studied with scanning electron microscope (SEM). The results showed that the best impact performance was obtained while fiber content was 10%, fiber length was12.5mm, mold pressure was 80tons, and jute fibers were modified by alkali. Furthermore, the result was compared with the corresponding research of glass fiber and carbon fiber reinforced polyurethane composites, and provided a theoretical basis for the application of the fiber reinforced polyurethane foam composites.
