Embodiment Construction

[0013] As shown in the accompanying drawings, the left half of the figure is cut on the composite material layer 2, and the lower left part shows a schematic diagram of the composite material layer 2 being formed by the oblique composite material winding tape 6; the right half is a cross-sectional view. In the present invention, it is an inner container 1 made of a high-strength aluminum alloy thin-wall inner lining or a plastic thin-wall inner lining, and a prestressed inclination angle is used to wind a high-strength fiber-impregnated epoxy resin-based composite material winding tape 6 outside the inner container 1. The outer surface of the material layer 2 and the composite material layer 2 is provided with a vertically and horizontally connected small groove 4, which is covered with an airtight outer protective layer 5, and the leak-picking holes on the airtight outer protective layer 5 are connected vertically and horizontally with the small grooves on the outer surface of ...

Abstract

The present invention discloses a composite material pressure container for holding liquefied gas, natural gas, liquid hydrogen and liquid oxygen etc. Said container includes internal container made up by high-strength alluminium alloy thin-wall inner liner or plastic thin-wall inner liner, its exterior is covered with a layer of composite material winding band layer which is made up by impregnating prestressed incidence-winded high-strength fibre with epoxy resin base composite material, and on the outer surface of the above-mentioned composite material layer several criss-cross communicated small grooves are cut, and its exterior is covered with closed external protecting layer with leakage-detecting holes which are communicated with above-mentioned small grooves and equipped with sensors mounted on these leakage-detecting holes.
