Experimental Study Of a New Composite Materials Firewall For Aircraft By Using Honeycomb Aluminum

Abstract

This article presents the experimental study of a new composite materials firewall for light aircraft. Currently, the firewall is made from conventional metallic materials which are used to isolate or protect the cockpit from any flame penetration from the engine compartment. For this reason, additional protection of machinery, wiring and plumbing are required. This protection is accomplished with the use of insulation blankets or other insulating materials at a cost and weight penalty. The use of composite firewall will eventually reduces the need for any additional protection, give a good weight saving and reduces the backside temperature. The composite firewall panel has been tested using the hair dryer with Agilent Bench Link Data Logger for 15 minutes. The temperature distributions across the back of the panel were presented.
