In this research, a hybrid composite material was prepared of epoxy as a matrix, and reinforced by iron (Fe) powder and iron oxide (Fe2O3) powder with a weight fraction 30%.
The composite material was prepared by the Iay-up method .It was studied may tests involves absorption test to find diffusion coefficient for the composite material after the immersion it in sometime specific time (3) weeks in different chemical solution as (H2O,HNO3,NaOH) concentration (0.1N) and the hardness test measure before and after immersion .
When increase the immersion time and the result showed the high diffusion in the water (0.839) and (0.288) in the solution (HNO3) and (0.237) in the solution of (NaOH).
