Etude des endommagements et de leur propagation en essais statiques et de fatigue sur composites carbone-epoxy

During static or fatigue testes on composite materials, several damages can appear at different load levels. These levels can vary with the following parameters : nature of the material, number of plies in each direction, stating sequence.This paper presents the results obtained by the adaptation of several methods to describe an quantify these damages : acoustic emission. X-rays, extensometry and comparison with theory calculation.
