Abstract:
. A container having one or more compartments therewithin, wherein an internal support structure extends through the compartments. The internal support structure is configured for enhancing the structural integrity of the container. Each compartment is defined at least in part by a preform. One or more preforms are assembled into a casting insert for forming the container. The casting insert includes one or more flow paths. A molten material is introduced about the insert, including into the one or more flow paths. The solidified molten material defines the external walls and the internal support structure of the container. The preform defining the compartment within the container can be retained therewithin or can be eliminated therefrom. The compartments within the container are in fluid communications, and an opening through an external wall of the container is configured for regulating fluid communications thereacross.
Abstract:
A structural component with at least two side members has a support structure that includes a partition with multiple curved portions forming cells. The partition connects to the side members and extends between the side members at least partially along straight lines. The partition may extend along one or more straight lines from one side member to the other. One structural component is a container with a wall about the internal support structure. The container cells may be formed with a core structure. The core can include a permeable storage material and may be retained after formation, or may be removed. In some cases the container wall has generally planar surfaces, which may include surface undulations. Core structures are also provided for forming structural components. Formation can include casting a material about a core structure within a mold to form a partition extending between two or more sides.
Abstract:
A fifth wheel hitch (100), comprising: a hitch bearing plate (10) having an upper surface (12); and a wear plate (16a, 16b) secured to the upper surface (12); wherein the wear plate (16a, 16b) comprises a metal comprises a ceramic component and a lubricious component, wherein the: wear plate (16a, 16b) has a first surface (22), and a second surface (24) wherein the first surface is an exposed surface and the second surface faces the upper surface, wherein the lubricious component has a total volume fraction that is highest at the first surface and is lowest at the second surface, wherein the ceramic component has a total volume fraction that is highest at the first surface and is lowest, at the second surface, and wherein the metal component has a total volume fraction that is highest at the second surface and is lowest at the first surface.
Abstract:
In some cases a composite cutting blade includes one or more cutting segments along a periphery of a hub segment. According to an example, the hub segment and the one or more cutting segments can comprise the same or different porous material. A metallurgical bond between the one or more cutting segments and the hub segment is created by a metal which infiltrates the porous material of both segments. The one or more cutting segments also include a cutting material which at least partially defines a cutting edge and/or a cutting surface of each cutting segment extending along the periphery of the composite blade.
Abstract:
A metal matrix composite article that includes at least first and second regions, first and second reinforcement materials, a metal matrix composite material occupying the second region of the body and comprising a metal matrix material and the second reinforcement component, a preform positioned in the first region of the body and infiltrated by at least the metal matrix material of the metal matrix composite material. The article further includes a transition region located proximate an outer surface of the preform that includes a distribution of the second reinforcement component comprising a density increasing according to a second gradient in a direction toward the outer surface of the preform.

Abstract:
A structural component having an internal support structure extending between outer wall portions of the component with one or more compartments included within the support structure. The support structure has support members including internal walls positioned between and/or defined by the compartments. At least one support member connects between the outer wall portions of the component to enhance the structural integrity of the component. The structural component, including the internal support, are cast from a molten material, and in some cases the support members of the internal support structure are formed with a rectilinear configuration. In some cases the cast structural component is a container and the one or more compartments are configured to store a fluid, such as a gas or a liquid. One or more preforms can be used to form a container and may be retained or eliminated from the container after casting.
