Abstract
To improve the mechanical properties of fiber-reinforced polymer matrix composites, hybrid systems based on unsaturated polyester (UPE) and epoxy (EP) resins with different ratios were investigated and applied to three-dimensional glass fabric-reinforced polymer matrix composites. The effects of hybrid matrix system were evaluated by flexural, tensile, impact, FT-IR and SEM experiments. It was observed that 5 wt% UPE in the hybrid system provided the maximum mechanical properties, particulatly the impact strength. Similar results were found when the hybrid matrix system was applied to the 3D fabric composite. The results from flexure, compression and interlaminar shear strength (ILSS) test were described for the hybrids.
