Patent ID: 7632353

Claim:
An apparatus for manufacturing a composite structure body by aerosol deposition method, the apparatus comprising a plurality of aerosol generators configured to generate aerosols by dispersing fine particles of more than one type of brittle material in gas, at least one nozzle configured to spray the aerosols, and a controller which controls at least one of a generated amount and concentration of said aerosols, wherein the plurality of aerosol generators comprises at least a first aerosol generator for generating a aerosol and for generating a second aerosol, the first aerosol generator and the second aerosol generator internally store fine particles of different types of said brittle materials, and said controller is configured to selectively control abundance ratios of the different types of brittle material fine particles in the aerosols spraying from said at least one nozzle to variably control an abundance ratio of the different types of brittle materials in the structure body.
