Abstract
The performance of shipboard electrical wire and cable during intense fire conditions is of increasing concern. Fire control equipment is increasingly electric power dependent, and the uninterrupted availability of electronic communication lines improves fire control operations. The concept of a flexible, lightweight polymer/ceramic composite wire insulation material which, under fire conditions, is converted to a porous, heat-resistant boron nitride ceramic insulator was explored in Phase I of this program. This concept has been further developed through changes in composition to improve strength under fire conditions, to reduce flame-spread, to improve hydrophobicity and to further explore processing methods. This development work indicates that the original concepts indeed sound, and that with some additional optimization the goal of a usable and producible fire-safe insulation will be achieved.
