ANALYTICAL AND EXPERIMENTAL APPROACH TO CUMULATIVE DAMAGE AND RESIDUAL STRENGTH PREDICTION FOR CFRE COMPOSITES.

Objective

The overall objective is to develop a predictive system for the residual life and residual strenght of carbon fibre reinforced epoxy (CFRE) composite materials subjected to cumulative service type damage.

The methodology is based on an understanding of defects and defect growth. It has two levels of focus with respect to damage type :
(a)delamination,
(b)matrix cracking.

Deterministic predictive models are being developed incorporating existing models and data :
(a)based on a full volume element approach,
(b)a beam lattice model which provides a simplified method for modelling damage growth. A computer model is being developed and tested for the probabilistic analysis of fatigue failure and reliability of the composite laminate.

New capability in NDE and opto-mechanics is under development. This will provide :
(a)input to the development of the predictive models,
(b)test data to permit evaluation of the predictive models by comparison with measured parameters,
(c)measurement methods to support the practical application of the models. Experimental data is also being generated from a fatigue test programme.
