摘要: Glass fiber-reinforced polymer composites have promising applications in infrastructure, marine, and automotive industries due to their low cost, high specific stiffness/strength, durability, corrosion resistance. Polyurethane (PU) resin system is widely used as matrix material glass superior mechanical behavior higher impact strength. PU are often manufactured using pultrusion process, shorter pot life of system. In this study, E-glass/PU a low-cost vacuum-assisted transfer molding process. A novel, one-part thermoset with longer adopted study. Tensile, flexure, tests conducted on both the neat composites. three-dimensional finite element model developed commercial code simulate composite for three different ene...
