ABSTRACT:
An integrated brake pad and back plate having a brake pad section formed from a first fiber reinforced ceramic matrix composite (FRCMC) material and a back plate section formed from a second FRCMC material. The brake pad and back plate are integrated because the sections are molded together to form an integral, unitary structure. The first FRCMC material used in the brake pad section includes a pre-ceramic resin in its ceramic state, fibers and possibly a filler material. The types and amount of these constituents are generally chosen so as to impart characteristics desirable in brake pads, such as high temperature and erosion resistance, and a high coefficient of friction. The second FRCMC material used in the back plate section includes a pre-ceramic resin in its ceramic state and fibers. In this case, the types and amounts of the constituents making up the second FRCMC material are generally chosen to impart the strength to the back plate section necessary to withstand compressive and bending forces placed upon it during braking.
