Abstract

Analytical work has been performed to predict the stress—strain curve of a carbon fibre reinforced polyamide 66. A typical stress—strain curve of this composite consists of three stages. Beyond the first linear stage the change of slope of the curve is attributed to the initiation and extension of cracks at fibre ends. Several theoretical models have been developed to take into account the development of cracks at various loading levels. Fibre volume-fraction, aspect ratio and orientation as well as fibre and matrix elastic properties and interface energies are the major parameters considered. The theoretical predictions are in close agreement with the experimental data.
