Abstract
A method for making a carbon composite material includes coating a carbon-fiber meshed cloth substrate with a liquid form of a carbon source and carbonizing the coating on the coated substrate by heating the coated substrate to a carbonizing temperature. The thickness of the coating on the substrate is such that, upon carbonization of the coating, the carbonized coated substrate retains porosity and a discernible surface texture.

A method for making an open-mesh carbon-fiber-reinforced carbon composite material formed substantially of carbon, the method comprising the steps of:
- coating a carbon-fiber meshed cloth substrate with a liquid form of a carbon source, the thickness of the coating being such that, upon carbonization of the coating, the carbonized coated cloth substrate retains porosity, is open-mesh having through pores, and is light-pervious;
- and
- carbonizing the coating on the coated cloth substrate by heating the coated cloth substrate to a carbonizing temperature so that an open-mesh, light-pervious carbon-fiber-reinforced carbon composite material having through pores and formed substantially of carbon is formed.
A method for making an open-mesh carbon-fiber-reinforced carbon composite material formed substantially of carbon, the method comprising the steps of:
- forming a liquid form of a carbon source by a technique selected from the group consisting of (i) admixing a liquid diluent to the carbon source and (ii) melting the carbon source;
- coating a single layer carbon-fiber meshed cloth substrate in the form of a flexible woven fabric with the liquid form of the carbon source, the thickness of the coating being such that, upon carbonization of the coating, the carbonized coated cloth substrate retains porosity, is open-mesh having through pores and is light-pervious;
- and
- carbonizing the coating on the coated cloth substrate by heating the coated cloth substrate to a carbonizing temperature of from about 600.degree. C. to about 2500.degree. C. so that a flexible open-mesh light-pervious carbon-fiber-reinforced carbon composite material having through pores and formed substantially of carbon is formed.
A method for making a single layer open-mesh carbon-fiber-reinforced carbon composite material formed substantially of carbon, the method comprising the steps of:
- forming a liquid form of a carbon source selected from the group consisting of thermoplastic resins and thermoset resins, the forming being accomplished by a technique selected from the group consisting of (i) admixing a liquid diluent to the carbon source and (ii) melting the carbon source;
- coating a single layer carbon-fiber meshed cloth substrate in the form of a flexible woven fabric with the liquid form of the carbon source, the cloth substrate having a discernible surface texture and the thickness of the coating being such that, upon carbonization of the coating, the carbonized coated cloth substrate retains porosity and a discernible surface texture similar to that of the cloth substrate and is open-mesh and light-pervious having through-pores;
- and
- carbonizing the coating on the coated cloth substrate by heating the coated cloth substrate to a carbonizing temperature of from about 600.degree. C. to about 2500.degree. C. so that a flexible, light-pervious single layer open-mesh carbon-fiber-reinforced carbon composite material having through pores and formed substantially of carbon is formed, the open-mesh carbon-fiber-reinforced carbon composite material having a discernible surface texture similar to that of the cloth substrate.
