Abstract

Acoustic fibers are potential candidates for developing sensors used in nondestructive evaluation (NDE) and process monitoring of composite materials. Acoustic fibers, like optical fibers, are easily embedded into polymeric composite materials. Because of the mechanical nature of the acoustic wave, acoustic fibers have direct sensing abilities on the variation of mechanical properties of their surrounding materials. Two experimental fiber acoustic sensors are developed. One is applied to detect the changes of properties of cured RHO-C rubber with temperature. Another is used to monitor the curing process of epoxy. Test results show the feasibility of applying the fiber acoustic sensors to NDE and process monitoring for polymeric materials.
