The present invention relates to a method for testing the influence of temperature using a firewall test body of an aircraft in order to prove fire resistance requirements of a firewall in an aircraft. According to an embodiment of the present invention, the provided method for testing the influence of temperature on a firewall in an aircraft comprises as follows: (a) a step of preparing a firewall test body which is formed by consecutively accumulating a first layer material formed of stainless steel, a second layer material formed of an insulator, and a third layer material formed of a composite; (b) a step of attaching multiple thermocouples to fixed positions on the surface of the third layer material in the firewall test body; (c) a step of fixating the firewall test body attached with the multiple thermocouples to a fixating fixture; (d) a step of applying flames at 2,000 deg F for 15 minutes at the fixed position on the surface of the first layer material in the firewall test body and, at the same time, obtaining temperature data at every two seconds for the 15 minutes using the multiple thermocouples; and (e) a step of analyzing the temperature data obtained by the multiple thermocouples. [Reference numerals] (S101) Prepare a firewall test body composed of a first layer material formed of stainless steel, a second layer material formed of an insulator, and a third layer material formed of a composite; (S102) Attach multiple thermocouples to fixed positions on the surface of the third layer material in the firewall test body; (S103) Fixate the firewall test body attached with the multiple thermocouples to a fixating fixture; (S104) Apply flames at 2,000 deg F for 15 minutes at the fixed position on the surface of the first layer material in the firewall test body using a flame generating device and, at the same time, obtain temperature data at every two seconds for the 15 minutes using the multiple thermocouples; (S105) Analyze the temperature data obtained by the multiple thermocouples |
