The invention relates to the technical field of material preparation, in particular to an efficient heat dissipation silicon nitride-based ceramic composite material and a preparation method thereof.The efficient heat dissipation silicon nitride-based ceramic composite material has the advantages that titanium oxide and magnesium oxide in a certain proportion are added into raw materials in the silicon nitride-based ceramic production process, and accordingly the silicon nitride-based ceramic can be high in density after being sintered; the silicon nitride-based ceramic has the advantages that the heat conductivity of the silicon nitride-based ceramic is effectively improved, so that the silicon nitride-based ceramic has high heat dissipation performance, the difficulty in preparing the silicon nitride-based ceramic can be reduced by filling titanium oxide and magnesium oxide, and the preparation operation of the silicon nitride-based ceramic is conveniently realized; according to the silicon nitride-based ceramic composite material and the preparation method thereof, the carbon fiber material is compounded on the prepared silicon nitride-based ceramic, so that the carbon element in the carbon fiber enters the silicon nitride-based ceramic, a silicon, carbon and nitrogen matrix is formed, and the prepared silicon nitride-based ceramic composite material has the properties of low thermal expansion coefficient, high hardness and high thermal conductivity.
本发明涉及材料制备技术领域，具体涉及一种高效散热氮化硅基陶瓷复合材料及其制备方法，本发明通过在对氮化硅基陶瓷生产的过程中向原料之中加注一定比例的氧化钛和氧化镁，可以使得氮化硅基陶瓷在烧结后具有高的密度，从而有效的提高氮化硅基陶瓷自身的热导率，使得氮化硅基陶瓷具备高散热性能，还可以通过氧化钛和氧化镁的加注降低制备氮化硅基陶瓷的难度，便于实现对氮化硅基陶瓷的制备操作；本发明通过向制备的氮化硅基陶瓷上进行碳纤维材料的复合操作，使得碳纤维内的碳元素进入到氮化硅基陶瓷内部，并形成硅、碳和氮的基体，制备出的氮化硅基陶瓷复合材料具备热膨胀系数低、硬度高和高导热率的性能。
