Modem aircraft use Carbon-Carbon Composite (CCC) materials for the heat-pack elements of the brake (Tarter, 1991). The elevated wear-rate mechanism of CCC brakes at low operating temperatures (<100°C) is well understood (Abbott, 1995). Oxidation of these friction materials increases between temperatures of 400°C - 600°C (Cullinan et al, 1989), which also increases the level of heat-pack wear. The current method for monitoring the life of CCC brakes is by visual inspection of the wear pin indicator. The limitation of this method is that there is no means of determining the causes of elevated heat-pack wear. This executive summary presents two innovative solutions to this wear-rate problem. The first solution monitors and records the amount of low-energy braking applications that occur on a conventional hydraulic braking system by processing the representative temperature and pressure information of the hydraulic brake fluid.
