The invention relates to a multidimensional nano-carbon reinforced friction material and a preparation method thereof, and belongs to the technical field of composite friction materials. The multidimensional nano-carbon reinforced friction material comprises a multidimensional nano-carbon reinforced friction material core plate layer which adopts a substrate made of a heat-resistant carbon
fiber 65Mn reinforced material; and multidimensional nano-carbon lining
layers are arranged at the upper end and the lower end of the substrate. The preparation method of the multidimensional nano-carbon reinforced friction material comprises the following steps: step one, weaving a
fiber cloth; step two,
curling and forming the
fiber cloth, impregnating the fiber cloth in resin,
drying, curing and cooling; step three, taking a steel plate,
punching and forming, carrying out hot leveling, carrying out heat treatment, washing and
drying, then taking the dried steel plate as a steel core plate layer ofa bottom layer; step four, carrying out ball-milling and alloying of nano-carbon and
copper powder; and step five, pressing and embedding the
copper powder containing nano-carbon into gaps of the nano-carbon lining
layers on two end surfaces of a formed friction plate by using a pressing
machine. The multidimensional nano-carbon reinforced friction material has the characteristics of light weight, high
specific strength, high
friction coefficient, low wear rate, low product
porosity, uniformity, compactness and better heat
fading resistance; the service life of the product is prolonged; and the fiber shedding phenomenon is reduced.
