A Fiber-Optic Sensor System for Total Lifetime Monitoring of Polymer Matrix Composites

Abstract

The most important progress has been made in the following two areas: strain sensitivity measurement and test geometry. The research on strain sensitivity measurement was focused on finding a system that did not have rapid stress relaxation. The transverse test geometry was shown to concentrate the transverse stress at the center of the sample. But the axial stress generated at the fiber-matrix interface was found to be greater than the transverse stress. Representative volume element analysis of the test geometry was also performed to investigate the effect of multiple fibers.
