a polarization maintaining optical fiber was embedded in a woven glass epoxy composite 3 point bend specimen and loaded to failure to determine the effectiveness of such fiber as a strain gauge and damage indicator. various fiber surface treatments were investigated and the validity of assuming structural strain continuity for those fibers was assessed by comparing experimental data with the structural strain level. results indicate that silane treated and buffered fiber can reasonably be considered to have adopted the structural strain, however care in treatment is necessary.
