Multi-dimensional nano-carbon reinforced friction material and preparation method thereof

Abstract

The invention relates to a multi-dimensional nano-carbon reinforced friction material and a preparation method thereof, belonging to the technical field of composite friction materials, including a multi-dimensional nano-carbon reinforced friction material core layer using a base material of heat-resistant carbon fiber 65Mn reinforced material; The upper and lower ends of the base material are provided with multi-dimensional nano-carbon lining layers. The first step: weaving fiber cloth. The second step: crimp the fiber cloth, impregnate it with resin, dry it, solidify it and cool it. The third step: take the steel plate for stamping forming, hot leveling, heat treatment, cleaning and drying as the bottom steel core layer. The fourth step: ball milling alloying of nano-carbon and copper powder. Step 5: Use a press to embed the nano-carbon-containing copper powder in the gap of the nano-carbon lining layer on both ends of the formed friction plate.

Extend product life and reduce fiber shedding.

Description

technical field [0001] The invention relates to the technical field of composite friction materials, in particular to a multi-dimensional nano-carbon reinforced friction material and a preparation method thereof. Background technique [0002] The friction clutch uses the friction between the friction pairs to realize the engagement, separation or asynchronous operation of the active part and the driven part of the mechanical mechanism or machine; the friction brake uses the friction between the friction pairs to realize the deceleration and speed limit of the mechanical mechanism or machine. or stop. The friction pair is composed of a friction plate and a pair of plates, and the performance of the friction pair mainly depends on the friction and wear performance of the friction plate. With the development of mechanical devices to the requirements of high load, high speed and high power, higher performance requirements are also put forward for friction devices, such as energ...
