摘要：

The ageing effects on a structural epoxy adhesive due to exposure to relatively high temperature and high humidity have been studied. Both the modifications to the bulk properties of the polymer and the reduction in adhesive strength have been considered. Concerning the mechanical properties of the bulk adhesive, various techniques have been exploited but in particular, viscoelasticimetric measurements have shown how the complex modulus alters with water uptake and the glass transition temperature decreases. Adhesive properties have been investigated using a torsional shear test Preliminary results suggest that this technique is well suited to the investigation of ageing effects.
