Abstract:
Plated polymeric articles having a composite layup structure and method of making the same are disclosed. A plated polymeric article comprises a composite layup having first and second polymer layers. The plated polymeric article further comprises a first metal plated onto the polymer. Additionally, methods for fabricating a plated polymeric article are disclosed. A composite layup is provided and compression molded into a desired shape having an outer surface. The outer surface of the article is prepared to receive a catalyst and then is activated with the catalyst. A first metallic layer is then plated onto the outer surface.
Abstract:
A nose cone may have a spinner including a main portion and an axially extending stepped portion. The nose cone may also have an annular aft support ring radially secured to the axially extending stepped portion. The nose cone may further include a fairing, which may be secured to the stepped portion.

Abstract:
Plated polymeric components for construction and building material applications are disclosed. An over-plated fastened assembly may comprise at least two components, a fastener joining the at least two components, and a metal plating layer deposited over the at least two components and the fastener. A plated polymeric component may comprise a polymer substrate, a fastener hole formed in a body of the polymer substrate and configured to receive a fastener, and a metal plating layer plated on a wall of the fastener hole to provide a plated fastener hole. In addition, a plated polymeric wear component may comprise a polymer substrate formed in a shape of a wear component, and a metal plating layer deposited on a surface of the polymer substrate. The wear component may be a washer, a bearing, a bushing sleeve, a bearing sleeve, an expansion joint seal, a blade wear pad, or a duct seal.
Abstract:
A composite component and a plated polymer component are disclosed. The composite component may comprise a body portion formed from an organic matrix composite, a first metal coating applied to a surface of the body portion, and an outer metal layer on the first metal coating that is erosion-resistant. The plated polymer component may comprise a polymer substrate, a metal plating layer applied to a surface of the polymer substrate, and at least one selectively thickened region in the metal plating layer. The at least one selectively thickened region may assist in protecting the plated polymer component against wear and/or erosion.
