The effect of tensile loading on the thermodynamics of Glass fiber reinforced polymeric composites laminates using an Infrared Camera by monitoring the surface temperature changes is reported here. Thermal response of specimens with various lay-up sequences was studied.

Experimental results show distinct thermal characteristics for each type of specimen layup. Temperature was found to be decreasing linearly with increased tensile stress in the elastic region. However, in the plastic region, depending upon the amount of plastic deformation, the composite specimens were observed to be following unique behavior that is characteristic of ply-orientations of the composite.
