1 December 1991Optical sensors embedded in composite materials
The use of embedded optical-fiber sensors in composite materials to measure strains and to detect delamination is investigated experimentally. The capability of embedded optical-fiber sensors to measure compression strain and to follow crack propagation in a composite material is demonstrated for carbon/epoxy and glass/epoxy composites. Details of the experiments and experimental results are presented.
