- This work investigated the thermo-mechanical behavior of (carbon/Kevlar) intraply hybrid composites. The carbon/Kevlar plies' orientation and sequential arrangement were varied. Carbon and Kevlar composites, as well as five different intraply hybrids (HFRPs) composite such as carbon-0°/Kevlar-90°, carbon-45°/Kevlar-135°, carbon-90°/Kevlar-0°, carbon/Kevlar (inter-changing layer), and carbon/Kevlar-45° (inter-changing layer) composites, and a plain epoxy panel, have been developed. The thermo-mechanical characteristics of the fabricated composites were estimated using a dynamic automated analyzer under changing mechanical and thermal load conditions. The DMA technique measured the HFRPs composite visco-elastic parameters by increasing the temperature from 30°C to 150°C at frequencies ranging from 1 to 20 Hz. Flexural test characteristics for neat epoxy, carbon fiber-reinforced composites, Kevlar fiber-reinforced composites, and carbon/Kevlar fiber-reinforced composites were estimated to aid the study. The experimentally measured versus analytically calculated viscoelastic parameters were related. The results revealed that carbon-90° oriented in warp direction/Kevlar-0° oriented in weft direction exhibited higher modulus and lower loss tangent followed by carbon/Kevlar plies oriented in alternate layers and carbon/Kevlar plies oriented in inter-changing layers at 45°. Carbon-0° introduced in the weft direction/ Kevlar-90° introduced in the warp direction, and carbon-45°/Kevlar-135° exhibited intermediate storage and loss modulus and a moderate loss tangent at the various frequency levels considered in the study.
