The use of structural adhesives, in the form of a one component mixture containing a thermosetting prepolymer and all the necessary additives with an adequate amount of a suitable curing agent, often spread on a reinforcing fabric is becoming more common in aircraft and related industries. Most of the research and development work deals with the nature and strength of the adhesive after bonding and its behaviour and aging in different environmental conditions. To the best of our knowledge, not much attention was paid to changes occurring in the prepolymerized adhesive before its use, changes which doubtlessly affect the performance of the final product.
