    摘要: Systems and methods for additive manufacturing of a metallic component using a metal-powder paste are described. The metal-powder paste is a mixture including a non-uniform metal powder and a flowable additive. The metal-powder paste is applied to a surface of a substrate and spread to thereby produce a uniform-thickness layer in areas corresponding to the metallic component. The flowable additive is driven off using thermal energy to thereby form a layer of the non-uniform metal powder having a uniform thickness. The non-uniform metal powder is then fused to the substrate to thereby form the metallic component.

    摘要: Methods for forming composite articles include providing a non-crimp fabric (NCF) comprising a plurality of fiber plies maintained in a layup by stitching, wherein the stitching exhibits a lower structural tolerance to heat and/or UV light relative to the fiber plies, selectively degrading the stitching in one or more areas using heat or UV light, draping the NCF on a contoured article, applying a polymer matrix material to the draped NCF, and curing the polymer matrix material to form a contoured composite article. The stitching can be degraded in regions of the NCF which, when draped on the contoured article, correspond to topological features of the contoured article. Degrading the stitching can comprise breaking the stitching. The fiber plies can comprise carbon fibers, glass fibers, and/or basalt fibers. The contoured article can be tooling and/or an automotive component. The NCF can be a bi-axial NCF.

    摘要: An in-mold coating includes graphene and a base material including an unsaturated polyester and/or a vinyl ester monomer. A part includes a main body formed of a polymeric sheet molding compound and an in-mold coating disposed on the main body, where the in-mold coating includes graphene and a base material that comprises an unsaturated polyester and/or a vinyl ester monomer. A method of creating an in-mold coating includes providing a base material comprising at least one of an unsaturated polyester and a vinyl ester monomer, and the method further includes adding graphene to the base material.
