New Insulation Constructions for Aerospace Wiring Applications. Volume 1. Testing and Evaluation
Abstract
This test program evaluated existing and new wire insulation constructions in a round wire configuration for aerospace applications. The goal of the program was to identify insulation candidates with balanced electrical, thermal, and mechanical properties. A comprehensive test program was developed to evaluate and statistically rank each wire construction. Testing was conducted using existing military and industry test methods. Forty-three tests were conducted on the wire samples evaluated. Initially ten insulation candidates and two baseline constructions MIL-W-81381 and MIL-W-22759 (cross-linked ETEE) were evaluated using the 15 most important tests. The majority of candidates consisted of composite constructions of polyimide film and a fluoropolymer layer(s). Four of the best performing candidates and the baseline constructions were further evaluated for overall performance by evaluating properties such as abrasion and cut-through resistance, chemical and fluid resistance, dry and wet arc tracking, and flammability and smoke generation.
