Abstract
A brake pad assembly having a consolidated lining comprised of an enhancement framework disposed within a tribological lining, the enhancement framework and tribological lining having substantially the same compressibility factor. The enhancement framework or tribological lining may advantageously be manufactured using an additive manufacturing technique.
Claims20
A brake pad assembly comprising:
- a base plate having a surface;
- a tribological lining extending from the surface of the base plate, the tribological lining comprising a substantially homogenous-mixture composite and having a first compressibility factor;
- and
- an enhancement framework disposed within the tribological lining, the enhancement frame-work having a geometrically-repeating arrangement in a plane substantially parallel to the surface of the base plate from which the lining extends, the geometrically-repeating arrangement comprised of a number of spring-like structures, the spring-like structures having a second compressibility factor and wherein the second compressibility factor is substantially equal to the first compressibility factor.

A brake pad assembly comprising:
- a base plate;
- an enhancement framework extending from the base plate and having a number of interlaced lattice structures, the interlaced lattice structures having a first compressibility factor;
- and
- a tribological lining comprised of a substantially homogenous-mixture composite, the tribological lining substantially infiltrating the enhancement frame-work and having a second compressibility factor that is substantially equal to the first compressibility factor.
1 more element
A method of manufacturing a brake pad assembly, the method comprising:
- assembling, using an additive manufacturing technique, an enhancement framework out of a first material, the enhancement framework having a geometrically-repeating arrangement;
- infiltrating the enhancement framework with a tribological lining comprised of a second material to form a consolidated lining;
- binding the consolidated lining to a backing plate;
- and
- curing the consolidated lining bound to the backing plate.
