Paper Abstract

This paper describes a manufacturing technique for embedding standard fiber-optic connection hardware in aircraft composite components. Three different concepts for detachable edge connections are presented. Embedding the fiber-optic connection hardware at the edges of the composite components is favorable since it entails easy manufacturing and maintenance. Carbon fiber/epoxy laminates were manufactured with embedded MT-ferrules and FC-ferrules. Using dummies in the manufacturing step solved the difficulty with laminate edge trim, which generally is a problem with edge connectors. The dummies were manufactured by polytetrafluoroethylene and had similar shape and dimensions as the embedded ferrules. The dummies could easily be removed after laminate curing and edge trimming, leaving embedded ferrules at the laminates edges, ready for connection. The manufacturing technique and fiber- optic connection were evaluated by manufacturing and loading a laminate with embedded MT-ferrule and optical fibers with Bragg grating sensors. The fiber-optic connection was confirmed and the strains measured by the Bragg grating sensors were in close agreement with the strains measured by strain gauges.
