Abstract
In this research we made a composite material consist of the matrix which is epoxy resin type (Thortex) with the reinforcing of chopped carbon fibers with volume fraction of 20%. Some mechanical properties were studied of prepared composite specimen after subjected different environments included (air, distilled water, KOH, HNO3) The normality for all these chemical solutions is )1(. Several mechanical tests are carried out on these samples, and these are: Bending test, Impact Strength test, Brinell Hardness test, every 14 days for 60 days.
