This paper describes British Airways experience with composite repairs since 1970. It includes the use of composite materials to repair metal structures such as Concorde wing leading edges and traces the repair of composite parts from Radomes starting in 1970, through B.747 body fairings and floor panels, to the repair of carbon fibre composite control surfaces and access doors on the B.757. Most of the repairs have used cold-setting resins with heat lamp assisted curing but some hot-setting adhesives and pre-pregs have been used. Effort is being made to develop techniques to facilitate the use of hot-setting adhesives. More information will be sought on diffusion and solubility coefficients of all types of adhesives to aid selection and improve the durability of repairs.
