As one preferred embodiment, elastic material packed layer 2 adopts rubber material.
Fibrous composite packed layer 3 is be wound around certain number of plies through resin-impregnated fibrous composite on elastic material packed layer 2 outer surface, and solidifying.Wherein fibrous composite can select carbon fiber, aramid fibre or glass fibre etc., and reisn base material can select polyester resin, epoxy resin or phenolic resin etc.
When being wound around fibrous composite, for ensureing pressurized container quality, adopting multi-shell curing technique, namely on elastic material packed layer 2, being first wound around certain thickness fiber, making it solidify, then being wound around second time, making it solidify, until product thickness reaches designing requirement.
To the designing requirement of fibrous composite winding layer 3 be: the laying angle of each laying, overlay thickness and fiber mechanics character should meet, when applying inner pressuring load to pressurized container, the strain value of the stack shell axis of fibrous composite winding layer 3 (shell) will much smaller than hoop strain value, and usual axial strain value at least should be less than hoop strain and be worth an order of magnitude.Be conducive to solving liner and problem that between fibrous composite winding layer and adjoining course, the easy unsticking in interface lost efficacy.
