Advanced Undersea Composites
Abstract
Approved for Public ReleaseThis proposal addresses the development and demonstration of a multifunctional undersea composite technology that leverages recent advancements in composites. Specifically, we will leverage a novel structural composite feedstock called TuFF developed at the University of Delaware under DARPA funding. The TuFF (Tailored Universal Feedstock for Forming) feedstock consists of a highly aligned discontinuous fibers (e.g., carbon, glass, etc.) preform in thin-ply format, which can be combined with thermoplastic or thermoset resins for prepreg, or used in dry form for infusion-based manufacturing processes. In previous ONR funding we have demonstrated how the TuFF material can be tailored to combine attractive structural and electromagnetic properties. This enables a variety of interesting applications. The objective of this proposal is to explore the use of Multifunctional TuFF for use in undersea applications. The three key areas that will be addressed are: (a) design, development and validation of structural multifunctional TuFF samples with attractive electromagnetic properties over different frequency bands, (b) development of a manufacturing approach that will allow fabrication of the multifunctional designs in non-planar geometries (e.g., cylinders and tear drop shapes) while achieving required structural, thermal and other environmental properties for undersea applications, (c) experimentally validate the planar and non-planar designs both electromagnetically and structurally.
