The objective of this effort is to explore the 'Smart Skins/Structures' concept of composite-embedded optical fibers and utilize it in conjunction with composite material developments in airborne electronic packaging. Both Polymer- and Metal-Matrix Composites (PMC and MMC) are being investigated. In order or composite-embedded fiberoptic links to function in naval aircraft, they must conform to the frequently severe environmental and physical constraints of avionics packaging. An experimental chassis and circuit card test assembly is planned and will achieve the following data links: transmitter to chassis, chassis to backplane, circuit card to backplane, and chassis on receiver. Graphite/epoxy-embedded optical fibers have been tapped which is preliminary to demonstrating a circuit card to backplane link. Other essential considerations of a composite-embedded fiber optic data link are connectors and couplers. Connectors are being studied and will be embedded in graphite- and Kevlar-reinforced panels to achieve signal transfer from one plane to another. Couplers will be embedded to achieve signal distribution in the backplane and individual circuit cares. Two types of couplers are being studied: biconical couplers and evanescent couplers.
