Due to their diverse qualities, glass and carbon fiber composites have been used in a wide range of applications. The composites are expected to have better thermal stabilities for long-term performance. Also, the thermal stabilities and thermal degradation behaviors of composites are crucial governing properties as well. Several successful initiatives and research have been undertaken in light of these issues, including attempts to blend various reinforcements with matrix materials to hybridize composites. Recent attempts to hybridize glass and carbon fiber composites, in particular, have been a startling approach. Taking this advantage of hybridization into consideration, the thermal properties of this the carbon fiber T300 and S glass fibers composite laminates with different stacking configurations fabricated through the hand layup method were investigated in this study. The influence of the thermal stability and thermal degradation behaviors for all Carbon(C)/Glass (G) stacking configurations (CGGC, CGCG, CCGG, GCCG, GCGC, and GGCC) were addressed and conclusions were drawn. Fracture surface analysis was also analyzed. From the experimental results, it has been observed that the possible optimal combination can be the stacking sequence CGCG for better tensile characteristics when it is subjected to unidirectional loading in the in-plane direction. The results obtained from TGA and DSC characterizations indicate that the stacking sequence is influencing the thermal behavior of hybrid laminates. The GCGC has exhibited the highest thermal stability and GGCC has exhibited the lower thermal stability compared to all other stacking configurations. From DTG curves the thermal degradation of CCGG configuration exhibited the highest degradation rate and lowest for laminate GGCC stacking configuration.
