  • Expansion reduction of metal component assemblies using composites
    Patent number: 9284981
    Abstract: Methods for minimizing thermal expansion in an assembly, e.g., a bearing assembly, for a vehicle are provided. The assembly has at least two components with substantially different linear coefficients of thermal expansion (CLTEs). The assembly has a polymeric composite with a first CLTE, a lightweight metal component (e.g., a housing) with a second CLTE, and a third component (e.g., a bearing component) having a third CLTE. The second CLTE is ?25% more than the third CLTE. The first CLTE is less than or equal to the third CLTE, so that the polymeric composite structure coupled to the first surface reduces radial thermal expansion of the first metal component and minimizes separation of the second surface of the first metal component from the second component.
