Tensile Properties of Glass-Basalt/Epoxy Interply Hybrid Composites

摘要

This study investigates the tensile properties of a glass-basalt/epoxy interply hybrid composite. The objective of this work is to develop an environmentally friendly hybrid composite material that has good strength and stiffness. These composites were fabricated through a vacuum-assisted resin transfer molding process. The glass/epoxy and basalt/epoxy composite were also prepared to compare the properties. The tensile strength of the hybrid composite improved as the basalt fiber content increased. However, we did not find a variation in the elastic modulus defined as the initial slope of the stress-strain curve for the hybrid composite under tensile loading. When the basalt fiber content of the total reinforcement became 40%, the fracture strain of the hybrid composite was higher than that of the glass/epoxy composite. From the test result, we knew that there is almost no difference between the tensile properties of the hybrid composites with different stacking sequences.
