Friction materials and their manufacture.

摘要

A non-asbestos brake pad is made of reinforcing fibres embedded in a binder material and the reinforcing fibres include a temperature resistant web-forming fibre in an amount of from 22 percent to 40 percent by volume of total solids in the pad. The pad also has an actual density of 75% to 88% of theoretical. A method for the manufacture of the pads is provided and includes the step of feeding the ingredients of the pad into a mold as an aqueous slurry.
