| This paper research the foil with powder overlay which have wide range of infrared radiation characteristic when been burned; and achieve my purpose that combine powder with pyrolytic graphite and have good dilatability. The final powder can jam visible spectrum,short infrared,middle infrared,log infrared and millimeter waves when it been burned. First of all selected the slow powder which burn temperature exceed 1000℃; secondly joined pyrolytic graphite in the slow powder, burn it can make graphite into graphite worm; thirdly selected the alloyed foil according to tests; fourthly selected appropriate glue after study slow powder and alloyed foil's engineering characteristic; fifthly researched the ignition characteristic which the foil with powder overlay had. After these tests, the foil with powder overlay have wide range of jam characteristic when been burned. |
