Paper Abstract

Acoustic waveguides embedded within materials provide a rugged and simple means for sensing stress, strain and other phenomena within smart structures and skins. The waveguides which function well in hostile environments can be used in two signal monitoring modes - transmit/receive and receive (listen), which is helpful when monitoring in noisy environments. They can be applied for monitoring cure as a material is made and subsequently for NDE during the material lifetime. In this paper applications of acoustic waveguides for monitoring material cure, viscosity, strain, and other phenomena are outlined, and the likelihood of the merging of the technologies of embedded optical and acoustic fiber waveguides is discussed.
