Estimating the term…
A pressure vessel of composite material built up by fiber wound around an elongated hollow body having at least one end fitting with an axially extending peripheral surface which has a plurality of protrusions distributed over the surface with portions of the fiber material passing over the end fitting and applied around the protrusions as to be peripherally and axially distributed thereover and molded into the composite material. The pressure vessel may also include two end fittings with different radii with the body having on an axially limited portion thereof radially extending pin-like protrusions distributed around its circumference with the fibers being wound in different directions relative to the axis on opposite sides of the protrusions with the directions being adapted to the radii of the end fittings.
A pressure vessel of composite material comprising a body having an axis with fiber material wound around said body and including at least one end fitting having an axially extending peripheral surface including a plurality of protrusions distributed over said surface, characterized in that portions of said fiber material pass over at least a portion of said peripheral surface of said end fitting and are applied around said protrusions with peripheral and axial distribution over said peripheral surface, said portions of said fiber material being moulded and fixed into said composite material.
