  • Patent number: 10605323
    Abstract: An elastomer bearing has an inner part, an outer sleeve that surrounds the inner part, and an elastomer body that is arranged between the inner part and the outer sleeve. The elastomer body extends from the inner part as far as the outer sleeve. The elastomer body comprises two liquid chambers, which are filled with a liquid and arranged one on top of the other in an axial direction, and a duct carrier arranged radially between the elastomer body and the outer sleeve. The duct carrier surrounds the elastomer body in a region of the liquid chambers and bounds the chambers. The elastomer body is vulcanized to the inner part. To reinforce the elastomer body, two, annular reinforcement inlays are embedded in the elastomer body, and form parts, separate from one another, of a cage that is embedded in the elastomer body.

  • Publication number: 20160221302
    Abstract: Composite materials that are configurable, their preparation, and their uses are described. A composite article includes a plurality of sheets positioned to interleave and partially overlap with each other and held together by interactions between the plurality of sheets and a compressive force across the plurality of sheets, wherein each of the plurality of sheets is infused with an elastomer and forms at least one smooth surface, wherein each of the plurality of sheets is in close contact with adjacent ones of the plurality of sheets, wherein an overlapping area of the plurality of sheets provides resistance to a shear force applied to the composite article.
