Abstract : In order to achieve optimum design of composite structures and bonded composite joints a full understanding of the fundamental non-linear mechanical behaviour of composite materials and the adhesive systems is required. The time-dependent behaviour of the adhesive systems is reasonably well documented, and has to some degree been accounted for in the design of bonded joints. However this is not the case for matrix materials in carbon fibre/epoxy resin systems. Whilst it is known that matrix-dominated behaviour of composites is highly non-linear, even at room temperature, this is often neglected in the design procedure. This report presents a study on the non-linear behaviour of a composite material and focuses on the shear behaviour of the carbon fibre/epoxy resin system used in the F/A-18, viz., AS4/3501-6. (MM)
