Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a friction pad made of a partial ceramic matrix derived from a pyrolyzed preceramic polymer, which contains embedded fillers. The pad is constructed in multiple layers: a tribological friction layer that interacts with a disc, a middle thermal insulation layer with function-specific fillers, and a vibration-damping shock layer. The design improves heat resistance, wear characteristics, and vibration damping.

Use CasesContent extracted from patent full text and abstract with AI.

  • Braking systems in automobiles, trucks, or railways
  • Industrial machinery that requires high-performance friction pads
  • Heavy-duty clutches and couplings for mechanical equipment
  • Elevator or escalator safety brakes
  • Wind turbine braking systems

BenefitsContent extracted from patent full text and abstract with AI.

  • Enhanced heat resistance due to partial ceramic matrix and thermal insulation layer
  • Improved wear resistance for longer product lifetime
  • Superior vibration and shock absorption for quieter and smoother operation
  • Customizable performance by using different function-specific fillers in each layer
  • Potential for lighter weight compared to fully ceramic alternatives

Patent Abstract

A friction pad (1) comprises partial ceramic matrix (2) of pyrolyzed preceramic polymer with embedded fillers and two excellent layers (I,III). The former layer is a disc tribological cooperating friction layer and the latter layer is a vibration-damping shock layer. Each layer includes one or multiple function-specific fillers (3,4,5,6,7). A third layer (II) in form of one or multiple function-specific fillers containing thermal insulation layer is formed between the former friction layer and damping layer. An independent claim is also included for a method for manufacturing friction pad, which involves stacking and laminating multiple layers based on preceramic polymer.
