    Inside StopFlex Long-Fiber Carbon Ceramic Brake Disc Manufacturing

    Inside StopFlex Long-Fiber Carbon Ceramic Brake Disc Manufacturing

    Built for Safety. Driven by Performance.

     

    • True Power Lies in the Fiber
      Unlike typical mass-market discs that rely on chopped strands, StopFlex harnesses the strength of continuous long-carbon fiber reinforcement. We weave these high-strength fibers into a complex 3D preform, establishing a structural toughness that fragmented materials simply cannot match.
    • Precision Engineering at 1,700°C
      Once shaped, the disc undergoes a critical vacuum silicon infiltration process at 1,700°C. This converts the preform into a robust C/SiC composite, ensuring the material is dense, stable, and ready for extreme heat.
    • Performance Without Compromise
      This advanced process yields discs capable of resisting cracking at temperatures up to ~1,800°C. For the discerning driver, this means superior heat management and unwavering structural integrity, delivering consistent, supercar-grade braking power.

     


    Step 1



    Toray T800 carbon fiber cloth and yarn, the lightweight raw materials for a STOPFLEX carbon ceramic disc.

    Carbon Fiber Weave

    Fiber Frame

     

    We tightly weave aerospace-grade T800 carbon fibers into a lattice (like high-tech carpet!), creating a lightweight disc "skeleton". Every thread is precision-aligned to handle insane braking forces.

     

    Step 2



    Layers of carbon fiber cloth stacked into a dense black brick, the preform for a STOPFLEX carbon ceramic disc.

    Resin & Reinforcement

    Layered Armor

     

    Each fiber layer gets coated in a secret sauce: carbon powder + silicon carbide + resin, dried, then stacked with reinforcement mesh—15 layers thick (think bulletproof lasagna!). This 30mm sandwich forms the disc’s core.

     

    Step 3

    Pressure Baking

    Density Locked

     

    We press-and-bake the stack at 180°C & 25 MPa (that’s 3,600 PSI!) for 2 hours. This fuses everything into a rock-solid "green body" (density: 1.6 g/cm³)—lighter than aluminum, stronger than steel.

     

    Step 4

    Silicon Fusion

    Born in a Vacuum

     

    The disc meets molten silicon at 1,550°C (sun-surface heat!) in a vacuum chamber. Silicon soaks into every pore, reacting to form silicon carbide ceramic—nature’s armor. Result? A disc that shrugs off 1,500°C track heat.

     

    Step 5

    Mill & Polish

    Race-Ready Refinement

     

    After cooling, we machine ventilation channels and diamond‑grind the surface to a mirror finish (≤0.02mm). The result? A disc with perfect cooling, precise fit, and minimal dust—ready for high‑performance use.

     

    Step 6

    Quality Control

    Rigorous Brake Testing

     

    We batch‑test every StopFlex carbon‑ceramic disc through brutal bench cycles: from 200 km/h down to zero, over and over, non‑stop for a full hour. During this ordeal, temperatures hover around 900 °C, and the disc must hold a rock‑steady friction coefficient from start to finish. That’s how we guarantee your brakes stay sharp—whether shredding laps or stopping on the street.
