Carbon fiber reinforced polymer composites (CFRPs) have increasingly gained importance among the scientific community as well as industry due to their high specific strength and light weight properties. However, CFRPs suffer from menace of high frequency vibration and low damping ability under normal operating conditions. This study aimed to experimentally investigate the effect of basalt fiber hybridization on vibration damping and tensile properties of carbon fiber/epoxy composites. Interply hybrid composites with varying basalt fiber percentages were fabricated through vacuum assisted resin transfer molding process and the vibration damping properties were evaluated from frequency response curves using half‐power bandwidth method. The results showed that incorporation of basalt fiber into the carbon fiber/epoxy composites significantly affected and enhanced damping properties with the increase in volume fraction of basalt fiber content. However, the results from tensile tests displayed significant drops in tensile strength and tensile modulus. POLYM. COMPOS., 39:E2274–E2282, 2018. © 2017 Society of Plastics Engineers
