This paper presents an inclusive review of recent developments in the thermal-mechanical endurance of composites made of polymers and sandwich structures. The large number of literatures are studied on phase change materials, smart materials, nanofiller based polymer composites, and natural fiber based composites. These combinations or materials provides the improved capabilities for energy storage, more supportable material, and good thermos-me-chanical properties. It also discusses the use of this information in various fields such as con-struction, energy storage, thermal management of electronic equipment, etc. This review sug-gests potential for future research directions to improve the thermal stability and performance of polymer materials and panels.
