Various techniques such as optical and electron microscopy, IR-ATR ESCA and SIMS have been used for failure mode analysis in polymeric adhesive joints. However, these techniques are not amenable for in situ, non-destructive examination of the failure surfaces as failure occurs. In order to develop in situ techniques, UV reflection and fluorescence methods are evaluated, as they can be applied via optical fibres to the actual failure surface. Failure surfaces of two types of adhesive joints are examined by UV reflection and fluorescence, complemented by FT-IR ATR studies. The first joint studied is PU on epoxy-coated steel. The second is PETP/PE/PETP. 8 refs. [Pg.82]
