Method for fabricating composite pressure vessels and products fabricated by the method

A process, and the product thereof, for making a composite vessel having at least one closed end, the process including the steps of: fabricating a thermoplastic liner for the vessel; overlaying onto the liner a layer of commingled fiber and thermoplastic material to obtain a composite intermediate structure; pressing and heating the composite intermediate structure to effect at least partial consolidation in apparatus which includes upper and lower silicon rubber bags, the bags having dimensions such that, during operation, their facing peripheral regions abut to encompass the composite intermediate structure; then placing the composite intermediate structure in a mold; heating the composite intermediate structure in the mold while applying a force, such as internal gas pressure, tending to urge the composite intermediate structure against and into the shape of the interior walls of the mold until the thermoplastic liner and the overlaid layer fully consolidate; cooling the mold and composite vessel until the composite vessel is solidified; and removing the formed composite vessel from the mold. The commingled fiber and thermoplastic material may either be wound onto the liner or laid on the liner in the form of fabric woven from the fiber and threads of the thermoplastic material.

Method for making thermoplastic composite pressure vessels

A process of making a composite vessel with superior mechanical and aesthetic characteristics includes the steps of: A) preforming a composite thermoplastic shell (e.g., by winding a commingled roving of fiberglass and a thermoplastic material onto a thermoplastic liner) having an opening for access to the interior; B) placing the shell (which may optionally be preheated) into a mold (which itself may optionally be preheated); C) introducing an inflatable bag containing a heater into the shell through the opening; D) heating the inflatable bag to a temperature which is sufficient to render the shell fluid while pressurizing the interior of the inflatable bag; E) continuing step D) until the shell forms against the interior walls of the mold; F) allowing the formed composite vessel to cool; G) removing the inflatable bag; and H) removing the formed composite vessel from the mold. Prior to step C), an insert having an opening may be juxtaposed in alignment with the opening in the shell such that, during step C), the inflatable bag is inserted through the opening in the insert. If desired for the intended purpose of the composite vessel, a portion of the exterior surface of the insert may be threaded such that threads are formed in the opening of the shell whereby the insert can be unscrewed leaving a threaded port into the vessel.

Portable heat generating device

A portable heat generating device in which fuel vapor and an oxygen supply (e.g. air) are directed through channels contained within a thin, flexible and compliant elastomeric sheet of material. Elongated catalytic heat elements, placed strategically within the channels, spontaneously interact with the fuel-air stream liberating heat energy. Means and methods are defined that permit flameless catalytic combustion to be uniformly extended over the length of each heat element, lowering power density but maintaining the overall power generated, permitting the use of many types of low temperature materials like plastics, polymers, and elastomers in the construction of the heater. The heat generation process is started by pumping an air stream into a reservoir containing a fuel source (e.g. methanol) thereby saturating the air stream with fuel vapor. The fuel vapor is mixed with a another stream of air to achieve a particular fuel/air ratio and directed into channels within the elastomeric sheet, reacting with the catalytic heat elements to produce flameless combustion. The warm exhaust gas is directed to a thermally controlled diverter valve. The valve senses the temperature of the liquid fuel supply and diverts some or all of the warm exhaust gas, as necessary, to heat the fuel and keep its temperature within a specified range. Exhaust by-products are passed into a miniature scrubber module adjacent to the fuel module. The scrubber absorbs any noxious components in the exhaust stream that may occur during start-up or rapid changes in operating condition.
