| titleOfInvention | A kind of gradient density carbon-ceramic composite material and its preparation method |
| abstract | The invention provides a gradient density carbon-ceramic composite material and a preparation method thereof, the method comprising: preparing a porous carbon fiber matrix; utilizing the porous carbon fiber matrix to prepare a carbon-ceramic panel with uniform density; The preparation times threshold of the carbon-ceramic panel of gradient density; determine the volume of the precursor solution required for each impregnation of the carbon-ceramic panel with uniform density; pour the precursor solution into the container containing the density according to the volume required for each impregnation In a pressure vessel with a uniform carbon-ceramic panel, vacuum impregnation, curing and sintering are carried out in sequence to complete one preparation until the number of preparations reaches the threshold value of the number of preparation times, and a carbon-ceramic panel with a gradient density is obtained; a carbon-ceramic panel with a gradient density A high-emissivity coating is compounded on the surface to obtain a gradient density carbon-ceramic composite material. The gradient density carbon-ceramic composite material prepared by the invention has both light weight, excellent temperature resistance and heat insulation performance. |
