Abstract: Systems, methods, and high performance electrochemical devices employing electroactive particles having a sandwich structure are described. The electroactive particle includes an electroactive layer between a pair of dimension-control layers. The electroactive layer includes an electroactive material configured to receive cations and experience a volumetric change in response thereto. The dimension-control layers are configured to inhibit planar dimensional changes of the electroactive particle such that the volumetric change of the electroactive layer occurs through a vertical dimension of the electroactive particle. The vertical dimension is orthogonal to the planar dimensions.

Abstract: Presented are fiber-reinforced polymer (FRP) sandwich structures, methods for making/using such FRP sandwich structures, and motor vehicles with a vehicle component fabricated from a compression molded thermoset or thermoplastic FRP sandwich structure. A multidimensional composite sandwich structure includes first and second (skin) layers formed from a thermoset of thermoplastic polymer matrix, such as resin or nylon, filled with a fiber reinforcing material, such as chopped carbon fibers. A third (core) layer, which is encased between the first and second skin layers, is formed from a thermoset/thermoplastic polymer matrix filled with a fiber reinforcing material and a filler material, such as hollow glass microspheres. The first, second and third layers have respective rheological flow properties that are substantially similar such that all three layers flow in unison at a predetermined compression molding pressure. These layers may be formed from the same thermoset/thermoplastic polymer material, and include the same fiber reinforcing material.

Abstract: Methods of producing an assembly, e.g., a bearing assembly, for a vehicle, with reduced thermal expansion in a linear direction as well as methods for minimizing linear thermal expansion in an assembly, are provided. The assembly has at least two components with substantially different linear coefficients of thermal expansion (CLTEs). The assembly has a lightweight planar metal component (e.g., a housing) with a first CLTE, a second component (e.g., a bearing component) having a second CLTE, and a polymeric composite with a third CLTE. The first CLTE is greater than the second CLTE. The third CLTE is less than or equal to the second CLTE, so that the polymeric composite structure attached to the first planar metal component reduces thermal expansion of the first planar metal component in at least one linear direction and minimizes separation of the second surface of the first planar metal component from the second component.

Abstract: Methods and devices for manufacturing paneled structures are provided. The methods include manufacturing a frame structure by additive manufacturing methods and scanning a surface of the frame structure to determine whether there is more than a nominal surface deviation at a location where a panel will be disposed. When there is more than a nominal surface deviation, the methods also include generating a panel to be disposed at the location of the frame structure, wherein the panel has an engagement surface that is complimentary to the surface deviation.
