Matech Advanced Materials and Biomedical manufactures calibration plates, biosensors, biocompatible materials and tissue. With strong capabilities in ceramic matrix composites from in-house synthesis of preceramic polymers to the fabrication of ceramic matrix composite components, MATECH provides wide-ranging solutions to the demanding requirements of the industrial, aerospace, and defense industries. MATECH routinely melt-spins ceramic fibers from SiNC, HfC, and TaC. Current bench-level capabilities include 4, 8, 10, 100, 250,and 500 filament SiC fiber tow. MATECH is developing structural ceramic fibers from silicon carbide, silicon nitride/carbide, silicon oxycarbide, tantalum carbide, and hafnium carbide. Preceramic polymer derived "green" fiber is produced and wound continuously. The firm's control over the rheological behavior of its preceramic polymers allows for easy melt-spinning. MATECH preceramic polymer technology allows fiber mat to be bonded together at the fiber cross-over points to enhance rigidity prior to curing. After curing, the initially thermoplastic preceramic polymer has been converted into a rigid thermoset polymer. At this stage, the preceramic polymer fiber mat can be heat treated to convert it into a ceramic. MATECH has developed methods of producing low cost, high temperature ceramic filter fabrication. MATECH continuous ceramic paper mat process permits control over fiber diameter, fiber volume fraction, permeability, and thickness. The firm has also developed high temperature CMC components of all kinds of varying shapes and sizes. MATECH makes C(f)/ZrOC(m), as well as braided C(f)/HfC(m) CMC's such as the Diverter Thruster.
