ABSTRACT

Resin impregnated pressure intobase material is an important parameter to control pressure

impregnation equipment in the fabrication process of composite structures. The paper describes the

built model of impregnated pressure dependencyto size and duration of structure fabrication. On

that basis, methods and order of calculations to determinethe requiredimpregnatedpressure for

fabrication of composite structures have been built. The specific calculation results are applied to

electromagneticpenetrable covertilesof antiship missile.
