Abstract
A composite article includes a lattice and an elastomeric section. The lattice includes a plurality of members that form an open-mesh frame defining a plurality of voids between the adjacent members of the frame. The elastomeric section is formed of an elastomer that is disposed about the lattice and within the voids of the lattice. The composite article may be a circular gasket, a gasket with a grip, a rectangular gasket, a vessel cap, a flask stand, and a handle for a hand tool.
Claims25
A composite article comprising:
- a lattice structure formed by additive manufacturing methods and including a plurality of members that form an open-mesh frame defining a plurality of voids between adjacent members of the frame;
- an elastomeric section formed of an elastomer disposed at least partially about the lattice structure and disposed within internal voids of the lattice structure;
- and
- a body monolithically formed with the lattice structure, a portion of the body extending from the lattice structure, the portion of the body disposed outside of the elastomeric section.

A composite article comprising:
- a lattice structure including a plurality of members that form an open-mesh frame defining a plurality of voids between adjacent members of the frame, the lattice structure formed of a thermoplastic, a polysulfone, a polyether ether ketone, or a thermoset;
- an elastomeric section formed of an elastomer disposed about the lattice structure and, the elastomer filling the plurality of voids of the lattice structure;
- and
- a body monolithically formed with the lattice structure, a portion of the body extending from the lattice structure, the portion of the body disposed outside of the elastomeric section.
