Research on the reliability of carbon/epoxy composite based on acoustic emission parameters

In order to study the operating life of structural components under the condition of load, the tensile damage experiments of carbon/epoxy composite are done in this paper. Then the mathematic model of the damage development of carbon/epoxy composite is built based on the experimental signal parameters, and then the reliability of carbon/epoxy composite is also discussed in this paper. Finally, the relationship between residual life of composite material and working-ours is deduced.
