Изобретение относится к области электротехники и может быть использовано в электрических машинах и транспорте. Материал, полученный способом совмещенного прессования и обжига, позволяет повысить износостойкость электрощеток и выход годного материала при его получении. Это достигается за счет введения в состав материала прокаленного кокса и в межпоровое пространство углеродной основы полимера фурфурилового спирта. Наличие в материале прокаленного кокса увеличивает его твердость, а введение полимера фурфурилового спирта делает материал более плотным и прочным. Кроме того, предложенный способ позволяет значительно сократить время изготовления материала.The invention relates to the field of electrical engineering and can be used in electric cars and transport. The material obtained by the method of combined pressing and firing, allows to increase the wear resistance of the electrobrushes and the yield of the material when it is received. This is achieved by introducing calcined coke into the material composition and into the interporous space of the carbon base of the furfuryl alcohol polymer. The presence of calcined coke in the material increases its hardness, and the introduction of furfuryl alcohol polymer makes the material more dense and durable. In addition, the proposed method can significantly reduce the time of manufacture of the material.
