Abstract

The invention relates to a method and device for online testing of friction materials and a closed loop control thereof, in particular, a method. The method comprises following steps of: (a) forming one or more friction materials of a brake pad; and (b) inspecting each of the one or more friction materials with one or more ultrasonic testers while each of the one or more friction materials are within a manufacturing line to determine if each of the one or more friction materials meet one or more desired material properties.

Description

technical field [0001] The present invention relates generally to the manufacture of friction materials for use in brake pads, and more particularly to in-line ultrasonic testing of friction materials during manufacture. Background technique [0002] Friction materials are used in various applications to slow down vehicles, such as automobiles, motorcycles or airplanes. Typically, friction material is also used to prevent movement of platform vehicles, parked vehicles, or both. Typically one or more friction materials are applied to the pressure plate to form the brake pad. One or more brake pads may be used within a braking system to apply brakes to a vehicle by moving the one or more brake pads into contact with a rotating brake rotor to create a clamping force. The clamping force is in turn used to slow the vehicle. [0003] Friction materials are typically manufactured using a variety of methods including: mixing of raw materials; forming the friction material into th...
