发明名称 Pressurizable envelope and method
摘要 An internally pressurizable lightweight high tensile strength multi-layered envelope is provided. An outer barrier layer of elastomeric semi-permeable material is mechanically bonded at a multiplicity of cites where substantially the entire distal surfaces of a double-walled drop thread linked fabric. The composite structure defines a substantially flat thin lightweight product which is capable of withstanding very substantial pressures.
