Abstract

Abstract: Hybrid carbon/glass composite rods consisting of unidirectional polyacrylonitrile (PAN)‐based carbon fiber (T700SC), braided E‐glass fibers, and thermoplastic epoxy matrix were fabricated with differing carbon/glass ratios (24K1P, 24K2P, and 24K3P). The cross‐sectional morphologies of the hybrid rods were observed using a digital microscope. Tensile properties and fracture behavior of the hybrid rods were investigated over a range of temperatures: −50°C, 0°C, 23°C (RT), 50°C, and 80°C. The tensile modulus and strength increased with increasing carbon fiber volume fraction, but decreased with increasing temperature. The Weibull statistical distribution of tensile strength for the hybrid rods was examined. The Weibull modulus increased with increasing tensile strength and decreasing void volume fraction of the hybrid rods. A Curtin‐type global load‐sharing model was applied to the hybrid rods to predict mechanical properties at different temperatures. Abstract :
