FORMING TEST FOR TRANSPARENT PLASTIC SHEET MATERIALS

Abstract

Development of a test procedure and apparatus for use in qualification testing of transparent plastic sheet material under military specifications is described. The procedure was used to differentiate the forming characteristics of five transparent plastic sheet materials that are supplied under five different Government Specifications for use in aircraft enclosures. The plastic materials were found to be sufficently different in characteristics at high temperatures to have distinctly different moduli of elasticity and to require different conditions of temperatures and pressures for forming. The forming parameters (thickness, pressure, time and temperature) which will permit qualification testing to differentiate the materials are given.
