ABSTRACT:
A lightweight structure for containing fluid under pressure, the structure having no inner seal sheath and including a cylindrical zone formed with a single sheath consisting of a composite material which avoids microcracking phenomena provided by differential pressure existing betweeen an environment surrounding the structure and the pressure of the fluid within the structure. The sealed sheath remains sealed up to a pressure that is very close to the burst pressure of the structure. The composite material is made up of a polyamide 12 matrix and of carbon fibers embedded in the matrix to withstand longitudinal and transverse components of the differential pressure.
