Testing and Stress Analysis of Curing Process of Epoxy Adhesive Coating

Abstract:

Three groups of strain gauges were embedded in the epoxy adhesive coating deposited on the steel substrate with different depths. The transverse and longitudinal strains during the curing process were tested. It was found that the transverse and longitudinal strains decreased remarkably when the curing time was lower 24h. At a longer curing time, the strains almost kept steady. In addition, the more close to the surface of epoxy adhesive coating, the higher the strains were. The solidification contraction stress in the epoxy adhesive coating during the curing process were also estimated, and the attempts were made to relate them to the restrained contraction of the epoxy adhesive coating.
