An inter-ply hybrid composite consists of at least two types of reinforcements along different plies in fiber-reinforced polymer composites. The tensile behaviour is deteriorated with increasing temperature, which possesses a severe concern that needs to be tackled before incorporating it into engineering applications. The tensile testing was done on the specimens at different temperatures (30 °C, 70 °C and 110 °C) by changing the hybrid ratio with different stacking sequence. The results reveal that by incorporating two layers of carbon fiber at the top end in glass fibers epoxy (GE) composite at 30 °C enhances the tensile modulus by 76.8% more than the control GE composite. Also, the strain to failure increases by 20.7% than carbon fiber reinforced epoxy (CE) composite by substituting one glass fiber by one carbon fiber at the top end. Although at 110 °C temperature, strain to failure amplifies by 9.3% than that of CE composite. The dominant modes of failure were observed under scanning electron microscopy of the failed specimens. © 2020 Elsevier Ltd. All rights reserved.
