Anisotropic heat-conducting light-weight high-strength ceramic-based composite material and preparation method thereof
The invention discloses a preparation method of an anisotropic heat-conducting light-weight high-strength ceramic-based composite material, which comprises the following steps: firstly, mixing an inorganic micro/nano sheet, an inorganic sintering aid and an organic matter solution to obtain dispersion liquid slurry, and preparing the slurry into a composite film with a layered structure by a specific solution film casting method; the prepared thin films are stacked and sintered into a three-dimensional continuous porous ceramic frame, and finally, resin is poured and cured after interface pretreatment, so that a series of anisotropic heat-conducting light-weight high-strength ceramic-based composite materials are obtained. According to the preparation method, simple preparation of the large-size anisotropic heat-conducting light-weight high-strength ceramic-based composite material can be efficiently realized. The method has universality, high efficiency and economical efficiency; the prepared ceramic-based composite material has excellent heat-conducting property and mechanical property, and has the characteristic of anisotropy of in-plane and out-plane heat-conducting property due to the intrinsic three-dimensional continuous ceramic frame of anisotropy of the ceramic-based composite material.
