Abstract

An enhanced method of evaluation of fibre-matrix adhesion in short fibre composites is developed. A parametric model of the fibre pull-out and failure is proposed. The parameters are estimated by means of the degree-of-fit criterion of the empirical and theoretical probability distribution function of fibre pull-out length. This length is experimentally measured on the fracture surface, while the theoretical probabilities are obtained by means of simulations. The practical results obtained are based on the known fibre length distribution in injection-moulded composites made from polymers and glass fibres.

Keywords : composite material, fibre pull-out and failure, length distribution
