Tensile, Shear, and Compressive Strength of Glass, Glass/Carbon, and Kevlar/Carbon Reinforced Vinylester for Marine Application

Composites are widely used in marine and aerospace applications due to their lightweight, resistance to corrosion and fatigue, and high specific stiffness and strength. This recent study used vinyl ester-based plain e-glass and hybrid composites of e-glass/carbon and kevlar-carbon/carbon fabricated by VARI methods. Tensile, shear, and compressive strength of composites are investigated according to ASTM standards. Comparison of the results to Al 6061-T6 was evaluated. Tensile and compressive strength of kevlar-carbon is superior to e-glass and e-glass carbon. The shear strength of e-glass/carbon hybrid composites is superior to e-glass and kevlar-carbon/carbon composites. Tensile and compressive strength of e-glass/carbon and kevlar-carbon/carbon hybrid composites are higher than Al 6061-T6. However, the shear strength of e-glass, e-glass/carbon, and kevlar-carbon/carbon composites are lower than Al 6061-T6.
