Abstract
A spline structure, in the form of an aeronautical brake drive bar, has wheel attachment points at its ends for engaging a wheel rim. Each wheel carries a regularly spaced series of these drive bars for engaging friction discs carried by the wheel hub. The main body of each brake drive bar is formed from titanium internally reinforced by composite blocks each comprising a bundle of silicon carbide fibers contained in a matrix that is diffusion bonded within the main body. Other spline structures can be formed in a similar manner.
