Applying Elastomeric Insulation Inside A Round Case

Elastomer wound onto inside surface in continuous strip. Technique being developed to apply elastomeric insulation to inner surfaces of axisymmetric cases. Requires modification of machine wrapping strip of elastomer on outside of rotating mandrel. Intended for coating insides of rocket-motor cases, technique also used to install elastomeric linings in pressure vessels, containers for chemical, and environmental chambers.
