Abstract: Implementations provide cold spray additive manufacturing (“CSAM”)-based fabrication of a complex multi curvature part (“CMCP”) by cold spraying onto a mold. Implementations achieve the desired shape and dimensions of a CMCP having variable surface thicknesses and utilize reinforcements integrated during CSAM. Reinforcements are integral to each CMCP as soon as fabrication is complete, and maintain stiffness, avoid fluttering, and provide other similar benefits. Implementations provide a stiff CMCP with multiple curvatures having fully controllable variable thicknesses. Integral reinforcements added during fabrication avoid tolerance issues by avoiding coupling non-reinforced CMCPs to reinforcements or other post-fabrication adjustments. CSAM-based CMCPs, having directly integrated reinforcements, exhibit superior tolerances that do not need to be re-worked or otherwise corrected after fabrication. Reinforcement attachment methods that have complex load transfer behavior are not necessary. In some implementations, simplifying load transfer increases the maximum load and decreases the overall weight of the finished CMCP.

Abstract: Composite airfoils of the present disclosure comprise a root section including a first surface. The airfoils comprise an intermediate section having a first surface and coupled with the root section at a first end. The airfoils comprise a tip section having a first surface and coupled at a first end with a second end of the intermediate section. The airfoils comprise a conductive material layer adjacent at least one of the first surface of the root section, the first surface of the intermediate section, and the first surface of the tip section. The conductive material comprises a first polymer, a second polymer, and a sulfonic acid.
