A special feature of the disc brake is the combination of friction materials that have different costs and properties.

The implementation of innovation guarantees:

• A minimum 30% reduction in the cost of disc brakes compared to carbon-based disc brakes.
• Reducing by half the volume of costly friction materials (such as carbon-based, metal-ceramic, etc.) used in manufacturing disc brakes.
• Reducing the cost of recycling friction material by half.
• Elimination of operational disadvantages of one friction material by leveraging the properties of another.
• A high and stable coefficient of friction across the entire range of operating temperatures experienced during braking.

Source of savings:

• Differences in cost and properties combined in friction units of friction materials.
• Possibility of combining expensive friction materials with materials of a lower price segment.

Testing the innovative disc brake:

The test was carried out on a full-scale stand. Comparative experiments were carried out for a disc brake with carbon-based working materials and an innovative disc brake. In the innovative disc brake, the brake disc of friction unit A is made of carbon-based material. Brake disc of friction unit B is made of steel.
Brake lining of friction unit A is made of carbon-based material. Brake lining of friction unit B is automobile lining.

Dependence of the friction coefficient f on heating time t.
1 – carbon-based disc brake;
2 – innovative disc brake.

The design of the disc brake is protected by patents of Ukraine.
