Development of a Polymer Composite Material with an Epoxy Binder for Producing a High-Pressure Cylinder

Experience of structure development, manufacture, and testing of a pneumatic pressure shell accumulator with a volume of 25 dm3 is presented. A binder composition for “cold” hardening based on ED-20 epoxy resin and Etal-23X cycloaliphatic amine is developed. In terms of rheological and physicomechanical properties the binder proposed is suitable for manufacturing shells by a “wet” winding method with low energy consumption for hardening.
