Aerospace A Pioneer in Structural Adhesive Bonding

My biggest mistake was to agree to the riveting of the window surrounds in the 

Comet 1 rather than insisting that they were Reduxed as planned 

Statement, just before his death, by RE Bishop, Designer of the de Havilland Aircraft Company s DH106 Comet 1. 

John Bishopp is a Fellow of the Institute of Materials, Minerals and Mining and a Member of the Royal Society of Chemistry. 

He has a deep knowledge of the science of adhesion and a long-nearly forty years-track record in the development of structural adhesives both as an individual bench chemist and then as the leader of Hexcel Composites worldwide Adhesive R and D Group.

Film adhesives, as their name implies, are solid at ambient temperature. Once the bonded joint is closed, heat is applied to affect cure and pressure is employed to aid the wetting of the pretreated substrate by the adhesive (for further information see Section 5.3.2.3 in Chapter 5 Aerospace A Pioneer in Structural Adhesive Bonding ). As the temperature rises, and before gelation begins, the adhesive matrix melts and begins to flow across the adherend to ensure that intimate wetting...
