Embedded Power and Signal Interconnects for Composites (EPIC)

The overall objective of this Phase I effort is to demonstrate structural integration of key and critical electrically conductive components, and assess their performance including strain and fatigue capabilities by developing and evaluating multiple concepts. To this end, NextGen will investigate multiple technologies and concepts which will lead to structurally integrated power buses, cables and wiring in a CFRP composite representative of missile structures. NextGen will down-select to a single concept by conducting structural and electrical testing and fabricate a proof-of-concept cylindrical composite article with embedded conductors and first-generation ingress-egress interconnects including intermediate wiring branches. At the end of Phase I, NextGen expects to achieve a TRL = 3-4. Guided by the Phase I design and test results, a potential Phase II effort will further mature the technology by performing a comprehensive set of laboratory and operational tests to achieve a TRL = 6-7. NextGen will also address cost, weight, ease-of-fabrication and reliability issues to facilitate near-term technology transfer.
