Flexible composites

This paper reviews the linear and non-linear elastic behaviour of flexible composites, which are based on elastomeric polymers and exhibit a usable range of deformation much larger than those of conventional thermosetting or thermoplastic polymer-based composites. The types of flexible composites examined are cord/rubber composites, coated fabrics and composites containing wavy fibres. The classical lamination theory forms the basis of analysing the linear elastic behaviour. Three analytical approaches have been developed for predicting the nonlinear elastic behaviour. The advancement in the predicability of analytical models enhances the utilization of flexible composites as load-bearing structural composites. The versatility of flexible composites in engineering applications lies in the fact that their load-deformation behaviour can be tailored by suitable selection of fibre/matrix systems and the design of fibre geometric configuration.
