Moisture and temperature degradation of double cantilever beam adhesive joints

In this work, the double cantilever beam (DCB) test is analysed in order to evaluate the combined effect of temperature and moisture on the mode I fracture toughness of adhesives used in the automotive industry. Very few studies focus on the combined effect of temperature and moisture on the mechanical behaviour of adhesive joints. To the authors’ knowledge, the simultaneous effect of these conditions on the fracture toughness of adhesive joints has never been determined. Specimens using two different adhesives for the automotive industry were subjected to two different ageing environments (immersion in distilled water and under 75% of relative humidity). Once they were fully degraded, they were tested at three different temperatures (?40, 23 and 80 °C), which covers the range of temperature an adhesive for the automotive industry is required to withstand. The aim is to improve the long term mechanical behaviour prediction of adhesive joints. The DCB substrates were made of a high strength aluminium alloy to avoid plastic deformation during test. The substrates received a phosphoric acid anodisation to improve their long term adhesion to the adhesive. Results show that even though a phosphoric acid anodization was applied to the adherends, when the aged specimens were tested at room temperature and at 80 °C, they suffered interfacial rupture. At ?40 °C, however, cohesive rupture was observed and the fracture toughness of the aged specimens was higher.     

Improved adhesion of LDPE films to polyolefin foams for automotive industry using low-pressure plasma

The use of polymer films for technical applications has increased considerably in the last years, since they offer good balanced properties. Polymer films find many applications as individual materials or as laminates with other films, foams, membranes, etc. In these cases it is necessary to improve the low intrinsic surface energy of polymer films to ensure their optimum mechanical performance. In this work, low-pressure glow discharge plasma with different gases is used to improve the adhesive properties of a low-density polyethylene (LDPE) film, to obtain the optimum mechanical response of laminates with polyolefin foam for automotive applications (steering wheels). The results show a remarkable increase in T-peel strength of the adhesive joints. Furthermore, since automotive industry is characterized by high technical requirements, the evaluation of the durability of the adhesive joints (in terms of storage conditions: temperature and relative humidity) shows that the T-peel strength of adhesive joints is subjected to an aging process that slightly decreases their mechanical performance, but does not restrict the use of these laminates in automotive uses.
