Abstract
Carbon-carbon (C/C) composites are a material that, due to its resistance to high temperatures, has been used for the nozzle throat section of rockets, but is highly expensive when fabricated using conventional processes such as hot isostatic pressing (HIP). In this paper, we report a newly-developed low-cost manufacturing process that uses film-boiling (FB) technology, the basic process for which was originally developed by CEA Le Ripault of France. We have confirmed that, by using this technology, we can increase the density of the carbon matrix around the carbon fibers to the same degree as those prepared using chemical vapor infiltration (CVI) but in a much shorter time. Having successfully used FB technology in the fabrication of SiC matrices using liquid polysilane (LPS), we hope that this technology will be extensively used in the near future.
