ABSTRACT:
A cogged component, especially a wheel, rack, pinion, spline, or similar structure, intended for the mechanical transmission of force. The body is of a composite reinforced with carbon fibers. The body is, in accordance with the invention, of fiber-reinforced ceramic comprising a lattice of essentially continuous carbon fibers and a matrix that contains carbon. The fibers in the lattice are sheathed in silicon carbide formed essentially by liquid silicon infiltrating the lattice and reacting with the carbon in the matrix. The cogs are constructed either of a similar fiber-reinforced ceramic with a load-accommodating fiber orientation or of a monolithic ceramic.
