Abstract
Structural adhesives are an important component of strengthening and repair techniques for structures. Adequate and proper curing of such materials is essential to achieve its desired strength and durability. In this study, the curing process of epoxy type Sikadur 330 is monitored using the electromechanical impedance (EMI) technique employing smart piezoelectric material, namely Lead Zirconate Titanate (PZT). Experimental results show that the PZT transducer embedded into the epoxy in liquid state is effective in monitoring the initial setting and the subsequent hardening process of a lab scale epoxy coupon. Rightward movement of both the PZT resonance peaks and the structural resonance peaks indirectly reflects the curing process. This study shows that the EMI technique is capable of monitoring the curing process of the structural adhesive. Future study shall focus on developing theoretical model capable of parametrically relate the electrical signatures to the mechanical stiffness and strength.
