Stress Analysis of Adhesively Bonded Repairs to Fibre Composite Structures,

Abstract

This paper describes a finite element method for analysing the behaviour of flaws in thn fibre composite sheets which are required with a bonded velocity. The method is an extension of the author's previous work on the repair of metal structures. As illustrative examples the repair of a hole and a crack in various graphite/epoxy laminates is discussed and it is shown that in each case a bonded overlay of either boron/epoxy or titanium provides effective repair.
