81MM Mortar Baseplate M-3 Pad Test

Abstract

The objective of this study was to solve the problem of seizure in socket to the baseplate. Neoprene, Fluorglas, and Viblon are investigated as pad materials. Static compression tests, soak tests, and pressure cycling tests of these materials are reported. The compression tests showed Fluorglas capable of withstanding the greatest compressive load (20,000 psi) and possessing the lowest recovery rate (.001 in./hr.). Soak tests in various environments revealed that Fluorglas suffered no apparent expansions or softening in any of the five media tested. The other materials suffered varying degrees of damage. The result of the three tests conducted was that Fluorglas seemed to hold up better in general than the other materials and was therefore recommended as a fix to the problem.
