由碳和铜构成的复合材料,一方面保持了石墨的弹性模量高,膨胀系数低和比重小的特点,又具有较大的导电和导热能力,因而有很大的实用意义,受到广泛重视。在电子工业中,这种碳/铜复合材料因其导热性比铝好,它可以代替铜制造半导体的电 The composite material composed of carbon and copper, on the one hand, has the characteristics of high elastic modulus, low expansion coefficient and small specific gravity, and also has a large conductive and thermal conductivity, which is of great practical significance and widely valued . In the electronics industry, this carbon / copper composite, because it is more thermally conductive than aluminum, can replace the electricity of copper in making semiconductors
