Abstract Scope |
Mulitfunctional composites have gained significant interest as they enable the integration of sensing and communication capabilities into structural, lightweight composites. Researchers have explored additive manufacturing processes for creating these structures through selective patterning of electrically conductive materials onto composites. Thus far, work in this area has been limited to fabricating simple, planar geometries due to an inability to adequately deposit conductive material over concave geometries. Proposed methods of integrating functional devices within composites have been shown to negatively affect their mechanical performance. In this work, we present a novel method for integrating electronic passives onto the interior surfaces of closed, complex continuous fiber composite structures via direct ink writing of conductive inks onto additively manufactured sacrificial tooling. Additionally, characterization of a complex composite surface featuring a patch antenna operating in the Ku band. The process is demonstrated as creating multifunctional composites without negatively affecting the mechanical performance of the structure. |
