<p>For use on a pressure vessel or the like, one form of the invention provides a protective shroud of interlaced fibrous material encompassing the vessel to contain fragments and dissipate shock waves upon accidental rupture or explosion of the vessel. The interlaced fibrous material of the shroud can be woven, knitted or otherwise fabricated and maintained in contact with the outer surface of the vessel. Another form of the invention provides at least one layer of unimpregnated fibrous material interiorly of the pressure vessel, in one embodiment, an inner composite includes a plurality of layers of filaments forming part of the thickness of the vessel, the inner composite being impregnated of cured epoxy material. At least one layer of unimpregnated fibrous material is laid up about the inner composite. An outer composite includes a plurality of layers of filaments forming part of the thickness of the vessel about the layer of unimpregnated fibrous material, the outer composite being impregnated of cured epoxy material. In another embodiment, the layer of unimpregnated fibrous material and the outer composite are laid up over an inner liner of the pressure vessel.</p> |
