Oxide Ceramic Matrix Composites

A Ceramic Matrix Composite specifically designed for high-temperature oxidation sensitive applications. These materials can be used up to 1200°C (2200°F) in air environments and are primarily used in both Aerospace and Gas Turbine applications. Oxide ceramic matrix composites products are based upon sol-gel derived matrices and 3M Corporation's Nextel™ fiber products.
