Abstract : Composite materials are increasingly used in a wide range of engineering applications due to their superior mechanical properties, corrosion resistance, and low weight. However, when exposed to thermal gradients or temperature fluctuations, these materials are subjected to thermal stresses that can compromise their structural integrity. The complex interaction of thermal conductivity, expansion coefficients, and phase mismatch between constituent materials introduces additional challenges in the accurate modeling of heat transfer and thermal stress distribution. This paper aims to investigate the fundamentals of thermal stresses and heat transfer mechanisms in composite materials. It explores the thermomechanical behavior under varying environmental conditions, highlights the analytical and numerical models used to predict performance, and discusses current challenges and future scope in enhancing thermal reliability.
