| Abstract: | Full scale C/C composites were prepared under a technology of rapid CVI(chemical vapour infiltration) using natural gas, whose period was short and cost was low. Mechanical property of C/C composites prepared under this technology was tested and analyzed, compared to the C/C composites fabricated by propylene through traditional isothermal CVI technology. Results show that tensile strength and modulus of C/C composites prepared under the novel technology increased by 12.0% and 20.1%, the flexure strength and modulus increased by 11.7% and 12.4%. |
