Abstract
A process for applying an interface coating includes the step of applying an interface coating material upon at least one surface of a fiber-based substrate. The interface coating material may be composed of a sizing agent, a ceramic powder and optionally at least one of the following agents: a dispersing agent, a deflocculating agent or a surface wetting agent.
Claims28
A process for applying an interface coating, comprising:
- applying an interface coating material upon at least one surface of a fiber-based substrate, said interface coating material comprising a sizing agent, a ceramic powder and optionally at least one of the following agents:
- a dispersing agent, a deflocculating agent or a surface wetting agent.
A process for manufacturing a composite material, comprising:
- dipping at least one surface of a fiber-based substrate into a slurry to form a coated fiber-based substrate on said at least one surface, said slurry comprising a sizing agent, a ceramic powder and optionally at least one of the following agents:
- a dispersing agent, a deflocculating agent or a surface wetting agent;
- heat treating said coated fiber-based substrate to form a fiber-based substrate having an interface coating;
- and
- impregnating said fiber-based substrate with a matrix material to form a composite material.
A process for manufacturing a composite material, comprising:
- dipping a plurality of unwoven fibers into a slurry to form a plurality of coated, unwoven fibers, said slurry comprising a sizing agent, a ceramic powder and optionally at least one of the following agents:
- a dispersing agent, a deflocculating agent or a surface wetting agent;
- processing said plurality of coated, unwoven fibers to form a coated fiber-based substrate;
- heat treating said coated fiber-based substrate to form a fiber-based substrate having an interface coating;
- and
- impregnating said fiber-based substrate with a matrix material to form a composite material.
A process for manufacturing a composite material, comprising:
- spraying a plurality of unwoven fibers with a coating material to form a plurality of coated, unwoven fibers, said coating material comprising a sizing agent, a ceramic powder and optionally at least one of the following agents:
- a dispersing agent, a deflocculating agent or a surface wetting agent;
- processing said plurality of coated, unwoven fibers to form a coated fiber-based substrate;
- heat treating said coated fiber-based substrate to form a fiber-based substrate having an interface coating;
- and
- impregnating said fiber-based substrate with a matrix material to form a composite material.
A process for manufacturing a composite material, comprising:
- spraying a fiber-based substrate with a coating material to form a coated fiber-based substrate, said coating material comprising a sizing agent, a ceramic powder and optionally at least one of the following agents:
- a dispersing agent, a deflocculating agent or a surface wetting agent;
- heat treating a coated fiber-based substrate to form a fiber-based substrate having an interface coating;
- and
- impregnating said fiber-based substrate with a matrix material to form a composite material.
