Fatigue Performance of Semiconductor Strain Gauges in GFRP Laminate

Abstract:

Semiconductor strain gauges have good potential for embedded structural health monitoring (SHM) applications. Silicon mechanical and thermal properties are similar to glass fiber. In this paper the high cycle loading of specimens with embedded and surface mounted semiconductor strain gauges is conducted. The base material is glass fiber laminate. Two different matrixes are used: polyester and epoxy resins. Hygrothermal loading is introduced to weaken the sensor-matrix interface and to imitate real application conditions.
