An Investigation of Thermoplastics for Use as 20mm Rotating Bands
Abstract
An empirical investigation has been conducted to screen a wide variety of plastic and adhesive candidate materials for use in 20mm rotating band systems. Eighteen different polymeric materials, representing seven general polymer families were used as rotating bands. Eleven different adhesives representing eight general types were utilized with the eighteen band materials to provide a total of forty-nine band material/adhesive combinations. Numerous processing variables were also investigated with the result that a total of one hundred thirty-one processing/material combinations were tried. The net results of this investigation was the identification of four material combinations which demonstrated substantial promise of serving as alternate materials to the nylon 12-253P rotating band system. Three of these four employ a domestically produced nylon 6 material (Zytel 211) with three different adhesives, P104, P-3, 253P. The fourth is a French produced nylon 11 material (BMNO) with the 253P adhesive. Gunfire results are presented and discussed and recommendations for following up the work conducted in this program and optimizing the performance of the most promising materials are made.
