Oxide Ceramic Continuous Filaments (Alumina, Mullite) are the result of years of intensive research and development, leveraging Saint-Gobain's expertise in advanced ceramics materials. These fibers are homogeneous, continuous, and specifically engineered for use in structural applications in high-temperature environments. Our fibers can be seamlessly combined with a range of matrices including ceramic, metal, and polymer, to deliver enhanced performance and outstanding mechanical properties.
Our team of engineers and R&D professionals has created a product portfolio that can withstand extreme temperatures exceeding 1100°C, making it the ideal solution for aerospace structural parts and various industrial applications.
