The current research presentsthe development of EPDM rubber including shape memory alloy. The Cu-Al-Zn alloy was modified with the coupling agent3-(Trimethoxysilyl) propyl methacrylate (TMSPM)and then incorporated into Ethylene propylene diene rubber (EPDM) by a 2-roll mill technique.The Cu-alloy behaved as superelasticity capability which can be used in various engineering approaches to smart materials. Microstructure, mechanical, rheological and magnetic properties of Cu-Al-Zn/EPDM composites was studied. The rheometericresults indicated that the incorporation of Cu-Al-Zn as a fillerenhance the curing process. Howeverthecuring time ofCu-Al-Zn/EPDMcomposites was reduced compared to the control sample without Cu-alloy. For the mechanical properties, increasing Cu-alloy loading inthe EPDMcomposites resulted inan increment of elongation at break.The addition of Cu based alloy as fillers improved the magnetization of composites with coupling agent when compared toEPDM rubber and Cu-Al-Zn/EPDMcomposites without coupling agent.
