Abstract The aim of this work is to investigate the influence of a variety of plasma treatments on the surface properties of an epoxy-based composite material and to establish a relationship between these properties and the subsequent mechanical behaviour of adhesively bonded joints. To this end, specimens were subjected to three different types of plasma treatment: two short treatments (2min) of He and He plus O2, and one long treatment (15min) of He plus O2. The variation in surface energy of the composite specimens was examined in each case over a period of up to 3 days… More >
