COMPOSITE BRAKE ROTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240019007 titled 'COMPOSITE BRAKE ROTOR
Simplified Explanation
The abstract describes a brake rotor with a composite structure. The rotor includes an annular body with opposite friction surfaces. The body consists of a core made of an Al-Si alloy, a thermal barrier layer made of a thermally insulating material, and a wear-resistant layer made of an Fe-Al-Si-Zr alloy. The wear-resistant layer forms one of the friction surfaces of the rotor.
- The brake rotor has a composite structure with multiple layers.
- The core of the rotor is made of an Al-Si alloy.
- A thermal barrier layer is applied on the core to provide thermal insulation.
- A wear-resistant layer made of an Fe-Al-Si-Zr alloy is applied on top of the thermal barrier layer.
- The wear-resistant layer forms one of the friction surfaces of the rotor.
Potential applications of this technology:
- Automotive industry: The brake rotor can be used in vehicles to improve braking performance and durability.
- Aerospace industry: The composite structure can be utilized in aircraft braking systems to enhance safety and reliability.
Problems solved by this technology:
- Improved heat dissipation: The thermal barrier layer helps in reducing heat transfer to the core, preventing overheating and potential brake failure.
- Enhanced wear resistance: The wear-resistant layer provides a durable surface that can withstand friction and wear, increasing the lifespan of the brake rotor.
Benefits of this technology:
- Improved braking performance: The composite structure and wear-resistant layer contribute to better braking efficiency and responsiveness.
- Increased durability: The use of a wear-resistant layer extends the lifespan of the brake rotor, reducing the need for frequent replacements.
- Enhanced safety: The improved heat dissipation and wear resistance ensure reliable and consistent braking, enhancing overall safety in automotive and aerospace applications.
Original Abstract Submitted
a brake rotor having a composite structure may include an annular body defining opposite friction surfaces of the brake rotor. the annular body may include a core made of an al—si alloy, a thermal barrier layer made of a thermally insulating material disposed on the core, and a wear-resistant layer made of an fe—al—si—zr alloy disposed on the core over the thermal barrier layer. the wear-resistant layer may define a first one of the opposite friction surfaces of the annular body.
