Abstract

Fiber-reinforced composite materials are increasingly being used in the construction of advanced aircraft structures. The detection of damage in such materials is critical to ensure safe application. An in-situ structural health monitoring system, either embedded in the composite structure or surface-mounted, would permit the timely detection of damage in such structures. There has been much work reported on the application of, for example, piezoelectric and optical fiber sensing technology for the detection of composite damage. In this paper we outline our approach using silicon microsystem technology.
