Brake pad friction material composition and preparation method thereof, and brake pad

Abstract

The invention discloses a brake pad friction material composition and a preparation method thereof, and a brake pad. The brake pad friction material composition comprises a binding agent, a reinforcing material and a friction performance modifier. The binding agent comprises modified phenolic resin and silicone resin. The reinforcing material comprises aluminum silicate fiber, steel fiber, carbonfiber, aramid fiber, polybenzimidazole fiber, polyphenylene sulfide fiber and polytetrafluoroethylene fiber. The friction performance modifier comprises mullite whisker, silicon nitride, yttrium silicate, silicon carbide, boron nitride, silicon dioxide aerosol, titanium nitride and titanium carbide. The friction coefficient of the brake pad manufactured by the adoption of the brake pad friction material composition is high and stable in the braking process, the wear rate is small, and the brake pad has excellent heat stability, is low in noise and shakes little.

AI Technical Summary

Benefits of technology

This patented technology describes how modifying certain types of fibers used for making improved composite materials has beneficial properties such as increased impact strength or reduced abrasion rates when compared to unmodified ones. Additionally, it mentions that adding these modifications may also enhance their overall functionality without affecting them significantly overall. These technical improvements make this type of modification possible even at extreme temperatures where traditional methods cannot be applied due to damage caused during manufacturing processes.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the properties of certain components within a vehicle's brakes without containing any metals like bronze or tin that could harm human health if they enter their environment through leaks from cracks formed due to factors like weather conditions.
