Abstract

Recently, smart composites have appeared as new materials. But, these materials require the integration of functional elements within the composite structure which generates some problems. This paper demonstrates how carbon fibers are not only the reinforcement but also the sensor to detect in-situ damages in CFRP laminates. (+/- 45 degree(s)) laminates were subjected to monotonic and creep tests under three-point bending conditions. The in-situ monitoring of electrical resistance variation and AE activity allowed the detection and the identification, at different stages, of various types of damage mechanisms (not only fiber fractures but also matrix cracks, debondings and delaminations).
