“…Although there have been some investigations'J into the nature of ions and radicals produced in the primary processes of the glow discharge, and in the volatile product^,^^^ very little attention has been given to the structure of the polymers, which are reported to have unusual electrical properties. [8][9][10] We present here the results of an infrared spectroscopic investigation of the structure of a number of polymers produced by this technique as part of a general investigation into the relationship between structure and properties of thin polymer films.…”

“…Inhibitors, that is to say thermal insulation materials, situated between the solid propellant and the motor case, are significant components of high performance solid propellant rocket motors in much aerospace and military utilization [1,2]. Aerojet Company has manufactured the inhibitor material by mixing asbestos fiber, silicon dioxide, and NBR in 1960s, and was applied in Pulse-motor [3]、and solid propellant such as Titan Rocket and Minuteman Missiles.…”

A missile motor has precision design and complicated components, responsible to propel the missile forward to reach an expected range. The motor must be protected by the inhibitor, which limits the high temperature from the burning of propellant to the generator to ensure safety of shell. The solid rocket propellant grain burns in the parallel layer according to a certain rule. Recently, NBR (Nitrile Butadiene Rubber) 、 EPDM(Ethylene-Propylene-Diene Monomer), Silicon Rubber and Polyisoprene are usually applied to the inhibitor matrix in solid propellant. The inhibitor can protect the external steel shell, and remains at a temperature of 300-400K under severe conditions of high temperatures of 2300-3700 K inside, free from any damage arising from internal high temperature. The oxyacetylene ablation performance test system is simple, economic and useful to estimate the thermal process of ablative materials. Based on this method, the relative thermal insulation effectiveness during the early stage of material research is determined.
