Hello everyone, I’m from Annat. Today, we’ll explore Aramid Fiber Kevlar in Brake Pads Mixes—its definition and why it’s a top choice for high-performance friction materials.
Aramid Fiber Kevlar, a high-strength synthetic fiber developed by DuPont, serves as a critical reinforcing component in Brake Pads Formula. It bonds with resins, friction modifiers, and fillers to form a robust matrix, directly elevating braking safety, durability, and stability.

Brake Pads Aramid Fiber Kevlar
Its advantages in brake pads are backed by concrete technical data:
1. Extreme Heat Resistance: It retains structural integrity up to 427°C, with thermal shrinkage ≤0.5% at 300°C. This prevents fiber degradation during severe braking (e.g., downhill or high-speed stops), avoiding sudden loss of braking force.
Car Brake Pads No Copper Formula
2. Outstanding Tensile Strength: Boasting a tensile strength of 28-34 cN/dtex—5 times that of steel at the same weight—it significantly boosts the brake pad’s anti-cracking and anti-fracturing performance. Tests show pads with Kevlar have a flexural strength 35% higher than those using conventional fibers.
3. Stable Friction Performance: It stabilizes the brake pad’s friction coefficient at 0.38-0.48 across temperature ranges (20°C-350°C). Even during 10 cycles of emergency braking (120km/h to stop), the coefficient fluctuation is less than 0.02, ensuring consistent braking feel.
Car Brake No Brass Formula
4. Low Wear & Quiet Operation: The fiber’s toughness reduces the pad’s volume wear rate to ≤0.5 cm³/(MJ) under standard conditions, extending service life by 25-30% compared to non-Kevlar pads. Additionally, its softness dampens vibration, lowering braking noise by 10-15 dB.
At Annat, we leverage Aramid Fiber Kevlar’s superior properties to craft premium brake pads. It’s the backbone of reliable braking systems, ideal for passenger cars, commercial vehicles, and high-performance vehicles alike.
