Abstract

Studies were conducted on the degradation of ILSS and compression strength properties of glass/epoxy composite specimens painted and unpainted that were subjected to immersion in a water bath maintained at 323 K. It is found that both ILSS and compressive strength of the composite degraded more in the case of unpainted specimens (coded L0) compared to the painted ones ( L1 or L2). Further, the specimens with a thicker paint coat ( L2) degraded less than those with a thinner paint coat ( L1).
