Damage sensing CNT/EPDM sheet was made for the prediction of microcrack in construction structure. Generally, EPDM is very rigid and stiff material. Sheet type of rubber state EPDM was manufactured by first ring opening polymerization. 0.5wt% CNT was added in EPDM resin to fabricate nanocomposites. Changed electrical resistance (ER) of CNT/EPDM film was analyzed to correlate tensile strength, elongation. Damage sensing of CNT/EPDM sheet was measured to predict the micro-cracks in structural body.
