Abstract
An encapsulated polymeric article is disclosed. The encapsulated polymeric article may include a polymer substrate and a metallic outer shell at least partially encapsulating the polymer substrate. The encapsulated polymeric article may be fabricated by a method comprising: 1) providing a mandrel in a shape of the encapsulated polymeric article, 2) shaping the metallic outer shell on the mandrel, 3) removing the mandrel from the metallic outer shell, and 4) molding the polymeric substrate into the metallic outer shell through a port formed in the metallic outer shell to provide the encapsulated polymeric article.
Claims6
A method for fabricating an encapsulated polymeric article, comprising:
- providing a mandrel in a shape of the encapsulated polymeric article;
- shaping an outer shell on the mandrel wherein the outer shell is formed from nickel, cobalt, copper, or an alloy containing at least 50 wt % of the foregoing elements;
- removing the mandrel from the outer shell;
- and
- molding a polymeric substrate into the outer shell through a port formed in the outer shell to provide the encapsulated polymeric article, wherein molding the polymeric substrate occurs after removing the mandrel and the encapsulated polymeric article is solid;
- and wherein the port is later introduced into the outer shell after shaping of the outer shell;
- and
- further comprising removing the port, by a process, from the outer shell after molding the polymeric substrate into the outer shell;
- and
- attaching at least one additional feature to the encapsulated polymeric article via at least one transient liquid phase bond.
