Carbon-carbon stator insert for aircraft brakes

摘要

The present invention relates to annular drive inserts which are placed within an annular opening within the brake disk. Preferably the annular drive inserts comprise carbon-carbon composite which has been treated with antioxidant. In a highly preferred embodiment the treatment is accomplished by vacuum impregnation. The antioxidant generally comprises a standard phosphoric acid based solution. This invention solves a need in the art for annular drive inserts that have improved resistance to oxidation and strength.
