Propellant-Liner Bond Test Improvement Program,
Abstract
The purpose of this program was to improve test methods for characterizing the propellant-linear-insulation bond system used in solid rocket motors. An industry-wide survey gathered information on current test specimen configurations and assessment methods. From this base an upgraded specimen was developed, then optimized, using two-dimensional finite element analyses and experimental evaluations. The optimized specimen is a rectangular flapped analog that has been improved to minimize bond stresses at the end plates. Also, it can be pulled at tens-shear angles to duplicate (analog) the tension and shear stress components in solid rocket motors. In experimental evaluation, the recommended specimen demonstrated excellent behavior when pulled in tension, shear, or combined loading.
