Product Introduction

The 380mm carbon ceramic brake disc is a short-fiber carbon ceramic brake disc. Primarily uses high-strength or high-modulus polyacrylonitrile (PAN) based carbon fiber (industry standard: T700) and needle-punched or braided quasi-three-dimensional (2.5D) structures to create the ceramic brake disc.

Key Features

1. Extremely lightweight, with an average friction ring weight of approximately 6156.3 g, improving vehicle range.

2. High heat resistance, able to withstand 1400–1650℃ long-term, with stable friction coefficient within 800℃, and no thermal fade.

3. Long service life, 300,000–500,000 km under normal road conditions, 200,000 km+ under track conditions (except for a few extreme cases).

4. Stable braking performance with low noise, minimal fluctuation in friction coefficient under dry and wet conditions, linear braking, and low noise without whistling.

5. Will not rust.

Ventilation Structure Description

Cooling Channel Design Description: A composite design of "main channel + radial auxiliary holes" is adopted, with the following specific features:

• Main Channel Design: The main ventilation channel runs along the circumference of the brake disc, utilizing the centrifugal force of the rotating brake disc to create an active suction effect, drawing external cool air into the channel. This improves heat dissipation efficiency by more than 30% compared to traditional straight channels.

• Auxiliary Hole Design: Radial auxiliary heat dissipation holes with a diameter of φ3 mm and a spacing of 20 mm are formed on the friction surface, connecting with the main channel to create a heat dissipation network. This allows for rapid heat transfer from the friction surface to the main channel for exhaust.

Structural Reinforcement: Reinforcing ribs are installed at the channel intersections to ensure that the ventilation structure does not affect the overall strength of the brake disc.

Production Process

First, in the mixing process, short-cut carbon fibers, silicon carbide powder, additives, and binders are added to a high-speed mixer in a specific ratio. Then, the mixture is molded using a custom mold (mold precision ≤0.02mm) and hot-pressed. The next step is carbonization, where the formed blank is placed in a carbonization furnace for carbonization. Then, molten silicon is infiltrated into the carbon skeleton. At high temperatures, the molten silicon penetrates into the pores of the carbon skeleton, reacting with the carbon to form silicon carbide (SiC). Finally, surface treatment is performed to improve the stability of the friction coefficient, wear resistance, and corrosion resistance.

Quality Control & Certifications

All products undergo rigorous pre-shipment inspections, including dynamic balance testing, flatness testing, X-ray flaw detection, and ultrasonic inspection.
