Abstract

Smart Structure Technology involving structurally integrated fiber optic reticulate sensor (SIFORS) systems could make obsolete the catastropic failures that have plagued aircraft, trains, cars......to date, [1]. The introduction of structurally integrated fiber optic damage assessment systems would permit structural integrity of a component to be monitored throughout its life. During manufacture and installation these built-in sensors would check for flaws or mishandling and therefore provide quality control. Internal damage generated by: impacts, manufacturing flaws, excessive loading or fatigue could be detected and assessed and growth of these damage zones also monitored.
