Abstract: The polymeric composites material considered as one of the most isolated materials, but they have a good mechanical flexibility. The main idea of modifying these materials to be one of the applicable materials in environmental aspects. Reducing the temperature inside buildings by coating them with the modified materials will give very good results in decreasing the electrical power used. In this study, polymeric composites material were prepared a by hand- layup technique from epoxy resin (EP) as a matrix and Copper (Cu) powder with average diameter (240.91 nm) as fillers with different weight percentage (5%, 15%,25%, 35%, and 45%) to resin. Glass transition temperature and Hardness testing were investigated. The results show the maximum Glass transition temperature (Tg) of (EP/Cu) composites were the value (58.949°C) at (65%EP + 35%Cu). Increase hardness with Copper concentration increase, and it has maximum values of (83.9) for (55%EP + 45%Cu). This composite can be used in the coating surfaces and floors to match the temperature of our country warm in summer.
