Abstract
The invention discloses a preparation method of a carbon-carbon composite heat-barrier material. The carbon-carbon composite heat-barrier material is composed of carbon fiber felt and a phenol formaldehyde resin. The method is characterized in that the carbon fiber felt treated with a highly oxidative liquid can obviously enhance the interface binding force between the carbon fibers and phenol formaldehyde resin and enhances the mechanical properties of the heat-barrier material while keeping lower volume density. The carbon-carbon composite heat-barrier material is simple in production technique; and the volume density is 0.16-0.18 g/cm<3>. When the volume density is 0.160g/cm<3>, the mechanical properties are as follows: the compression strength can reach 0.73 MPa (face direction) and 0.4 MPa (two-side direction), and the bending strength can reach 3.52 MPa (face direction) and 1.86 MPa (two-side direction).
