Paper Abstract

In this paper, we report the results of a series of experiments undertaken to quantitatively evaluate the accuracy of a fiber optic Fabry-Perot strain sensor embedded in a material system. The optical fiber sensor is embedded in three material systems containing different physical attributes to simulate a variety of local stress fields. The material systems, which included a homogeneous material, a model system, and a composite laminate, are subjected to tensile and compressive loads to evaluate the performance of the sensor under each of these conditions. In each test, the data obtained from the optical fiber sensor is compared to data from externally attached resistance strain gages for validation purposes. Results demonstrate that optical fiber sensors provide highly accurate results if sufficient chemical and/or mechanical load transfer mechanisms are present.
