Introduction - Friction

Our material is Biodegradable which aids reinforcement and toughness in friction linings/shoes/pads. Its fiber-like structure gives improved friction stability while reducing cracking. Blending into formulations can not only increase strength of friction materials, but also improve shear strength and impact strength. Our material is good at stabilizing friction coefficient. Recommendation dosage: 8% to 15%, Maximum 20%. The actual dosage is subject to customers formulation design.  

The hardness of mineral fiber, steel fibers, ceramic fibers are usually higher with shot unavoidably, commonly these fibers lead to noise. Also our material do not produce black ashes, but it can reduce phenomenon of falling ash when braking.

For Brake Pads

Picture is the illustration of the contact situation between the pad and disc. A transparent disc is moving from left to right. Some of the wear particles pile up against the contact plateaus and create secondary plateaus. A flow of wear particles in the gap between the pad and disc wear the lowlands of the pad through three-body abrasion .

Applications



It is widely used as a friction enhancing material in automobile brake pads, train brake shoes, Clutch and other friction materials.

 

Characteristics

The aluminum titanium powder has obvious effect in increasing friction in low, medium and high temperature environments.

Dosage

It is recommended to add the proportion of 3-8%, which can reduce the adding ration of resin and other high price materials to lower the cost.

  • Reinforcement and toughness: Improving mechanical strength.
  • Stable Friction Coefficient: Excellent Fiber Shape can behave as anchoring points to facilitate the formation of third body layer, creating a suitable condition for stable friction coefficient.
  • Good NHV performance: Gypsum Fiber Mohs Hardness is 2-3, providing the friction material with the mechanical strength but without damaging the metallic surface of the rotor. The material will facilitate abrasives for the third body layer but it will not create a hard contact point, avoiding rotor/disc scratch and potentially creating less vibrations and noise.
  • Improve comfortability: Softening the material of the friction block.
  • Improvement in corrosion for friction materials: Thermal behavior is also interesting as the material will lose small amounts of water during the friction material production process without losing its fiber shape. The material will then be able to be rehydrated and this represents a potential improvement in corrosion for friction materials.
  • Less Dust: Raw material is safe Food-grade Gypsum block.
  • Heat Resistance upto 1000 °C
