Ceramic composite material

The invention provides a ceramic composite material which is formed by compounding a ceramic layer, a graphene layer and a metal layer; the graphene layer is located between the ceramic layer and themetal layer; the thickness of the graphene layer is 1-2 mm; the thickness of the ceramic layer is larger than 4 mm; the thickness of the metal layer is 2-3 mm; the metal layer is made of copper; the ceramic layer is a si3n4 ceramic layer; the thickness of the ceramic layer accounts for 60-70% of the total thickness of the material. The ceramic is compounded with the other two different materials,so that the toughness and the pressure resistance of the ceramic can be effectively improved, the service life of the ceramic composite material can be prolonged, and the failure rate of the ceramic composite material can be reduced. 本发明提供一种陶瓷复合材料，由陶瓷层、石墨烯层及金属层复合而成，其中，石墨烯层位于陶瓷层与金属层之间，石墨烯层厚度为1-2mm，陶瓷层厚度大于4mm，金属层厚度为2-3mm。金属层为铜材质，陶瓷层采用si3n4陶瓷层。陶瓷层占材料总厚度的60%-70%。本发明采用陶瓷与另外两种不同材质进行复合，能够有效提高陶瓷的韧性及抗压性，有利于延长使用寿命，降低故障率。
