DENSIFICATION OF CARBON/CARBON COMPOSITES WITH AN EMBEDDED CHANNEL NETWORK

Patent Pending

• This novel approach to densifying Carbon/Carbon Composites takes advantage of a micro-channel network. Using an isothermal heating method creates a natural thermal gradient in which the interior is cooler than exterior. By flowing the gaseous carbon source through the composite’s micro-channels, gas flow can occur from within the composite to the outside.

• This invention shortens processing times of fabrications, reducing costs compared to traditional methods. In this method, the C/C Composites have an embedded micro-channel network, which will be used to flow a gaseous carbon source resulting in a denser carbon material….

DENSE AND SELF-HEALING ZrB2-SiC ANTI-OXIDATIVE MULTILAYER COATINGS FOR CARBON/CARBON COMPOSITES 

Patent Pending

• The invention applies a protective coating to carbon/carbon (C/C) composites with novel self-healing, protective coatings using ZrB2 and SiC.  

• The invention provides a multilayer coating for carbon/carbon composite structures to provide a protective layer to prevent loss of carbon mass from oxidation when operating temperatures exceed 500°C under oxidizing conditions.   The coatings are selected for their adherence to the C/C composites and the similarity of their coefficients of thermal expansion to the composites being protected.  

• Potential applications include concentrated solar power target protection, rocket nozzle coatings, space vehicle heat shields, and airplane disc brakes….
