Investigation of tensile properties of hybrid polymer matrix and glass fiber reinforced polymer composites

Abstract

In this study, hybrid matrix mixtures with different matrix phase resin types were prepared and 5%, 10% and 20% chopped E type glass fibers were added to these mixtures. The orthophthalic, isophthalic and terephthalic polyester resins were each mixed with each other and epoxy-based vinyl ester resin in different combinations as double and triple hybrid matrix mixtures. The tensile properties of the composites produced were determined. As a result of the study, as the fiber ratio increased, the hybrid matrix composites were seen to turn into a more rigid structure and the highest tensile mechanical properties were obtained in the blends containing 20% fiber and vinyl ester resin. It was determined that orthophthalic + vinyl ester (OV) mixture has the highest rigidity in all mixtures prepared with two types of hybrid resin matrix. When the tensile properties of the composites with two types and three types of hybrid resin matrix were compared with each other, it was seen that there were no significant differences.
