Application Summary AI generated

GB/T 46904-2026 specifies the classification, technical requirements, test methods, inspection rules, and packaging for polycarbosilanes used as precursor materials in the production of silicon carbide (SiC) ceramic fibers and ceramic matrix composites. It is primarily applied in the aerospace industry for manufacturing high-temperature-resistant structural components, such as thermal protection systems and engine parts, where material purity and consistent molecular weight distribution are critical. The standard also guides quality control in raw material procurement and batch testing for suppliers and manufacturers of advanced ceramic materials.
