METHOD OF FABRICATING COMPOSITE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for fabricating a composite structure with good productivity stably for a long time in making the composite structure by blowing an aerosol containing particulates at a high velocity to a base material. SOLUTION: The aluminum oxide particulates to which an internal stress is imparted are prepared and are packed into an aerosol generator 103 and gaseous nitrogen is introduced into the aerosol generator 103 packed with a powder mixture through a conveyance pipe 102 from a gaseous nitrogen cylinder 101 to activate the aerosol generator 103 and to generate the aerosol containing the aluminum oxide particulates. The aerosol is introduced through the conveyance pipe 102 into a gas heating apparatus 104. The aerosol is heated in the apparatus 104 to a prescribed temperature and is jetted as a particulate beam at a high velocity toward a substrate 109 from a nozzle 107 installed in a structure fabricating chamber 106 through a conveyance pipe 105 with a heat insulating function. The temperature of the particulate beam is detected by a thermocouple 108. The substrate 109 is oscillated simultaneously when the particulate beam is jetted, by which the structure is formed.
