An elastomeric layer can be applied to the surface(s) of the tool body and a resinous material, such as a fiber reinforced material, applied to the elastomeric layer, wherein the elastomeric layer inhibits the movement of resin from the resinous layer into the porous ceramic body, and the resinous layer defines the mold surface.

Abstract: Disclosed are various embodiments of an extruded expandable barrier, and various processes and systems for manufacturing the same. Using various extrusion processes to form an extruded expandable barrier allows for a reduction in tooling costs while also allowing more flexible barrier designs. Such designs can be specifically tailored for a particular cavity or cavities to ensure that the barrier fills the cavity after expansion. In addition, design changes can occur with little to no tooling changes.

Abstract: A composite article having an elastomeric composition with a blowing agent having an activation temperature and providing at least one structural member defining a fixed gap. The composition is formed below the blowing agent's activation temperature into a solid elastomeric member approximately the thickness of or larger than the gap. The elastomeric member is assembled into the gap, which may place the elastomeric member in a state of compression in the gap. The elastomeric member is then expanded by heating it above the activation temperature. During expansion, the escape of the gas produced is limited to increase the state of compression of the elastomer in the gap by means of confining any free surfaces or by including a platy filler such as nanoclay in the composition.

Abstract: In the manufacture of carbon-carbon composite brake discs, migration of anti-oxidant substances into the friction surfaces is prevented by limiting or eliminating surface porosity in the carbon-carbon composite brake materials. The method includes infusing a suitable resin into pores in surface layers of the carbon-carbon composite disc and then charring the resin-infused disc to convert the resin in the pores to pyrolytic carbon. The resin may be infused into the carbon disc by submerging the disc in a molten resin. Prior to submerging the disc in the molten resin, the disc may subjected to a vacuum to remove air from the pores. While the disc is submerged in the molten resin, the pressure in the pressurizable vessel may increased to force the molten resin into the open porosity of the disc.
