摘要: A structural epoxy adhesive has been studied under humid ageing conditions, both as a bulk polymer and an adhesive, in torsional cleavage (wedge) tests. Diffusion of water within the polymer, measured by gravimetry, was found to be good agreement with Carter Kibler model. Physical properties decreased increasing content. correlation between decrease joint properties. Fracture surfaces have also explained using Given various types failure, extent each depending on time immersion, simple model is proposed estimate overall energy adhesion, G* (an effective average linked three distinct failure), function time.
