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
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.
value (58.949°C) at (65%EP + 35%Cu). Increase hardness with Copper
