摘要

Phenolic-rubber foams were developed at NOI, and fabricated into. 6"/47 plugs which were successfully rammed at 0°, 90°and 120°P. Preliminary firing tests in a 40mm. gun indicate a degree of fragmentation comparable to natural cork plugs. Further development of foam materials for 5"/54 plugs is planned Compatability with propellants and the effect of simulated handling, transportation procedures and temperature cycling on ramming will be studied.
