Investigation of Experimental Lightweight Firewall Materials for A/C Engine Bay Applications.

摘要

An evaluation of fire-resistant materials was conducted to identify possible replacements for stainless steel for use as aircraft firewalls. The materials were subjected to the standard firewall (MIL-I-83294), fire-penetration test. In addition, each sample passing this test was further evaluated on weight, thermal protection, and maintenance requirements. An attempt was made to correlate physical properties to fire penetration test performance, but was not successful due to the lack of physical property information. The report identifies those materials which should be developed for use as firewalls and fire-hardening materials on aircraft. (Author)
