The effect of the type of amine hardener on the mechanical properties of epoxy was investigated with diglycidylether of bisphenol A(DGEBA) epoxy resin, cured with aliphatic amine hardener, triethylenetetramine(TETA), and aromatic amine hardener, 4,4’-diaminophenylmethane(DDM). Also, to obtain epoxy with high conversion ratio and better mechanical properties, epoxy resin and hardeners were cured and tested under several different conditions. The resin and each hardener were blended with 1:0.9, 1:1, and 1:1.1 equivalent ratio, and in case of DGEBA/DDM, the specimens were prepared under various post-curing conditions. The mechanical properties of epoxy were analyzed with compression and hardness tests. |
