摘要： A method and apparatus for molding composite articles can include a pair of opposed mold sections having first and second molding membranes that define a mold plenum. The mold sections have a thin-skin mold section configuration. Each mold section can be filled with a gas backing. The temperature of the mold plenum can be controlled by regulating the temperature of the gas backing.

摘要： A method and apparatus for molding composite articles can include a pair of opposed hollow mold sections having first and second molding membranes which define a mold plenum therebetween. Each mold section can be filled with a substantially noncompressible, thermally conductive fluid. The temperature of the mold plenum can be controlled by regulating the temperature of the thermally conductive fluid. Sensing of various parameters during the injection and curing processes of the molding fluid, for example pressure, flowrate, temperature and filling of the plenum can be used to optimize the molding process.

摘要： An apparatus for molding composite articles includes a pair of opposed matched-tool mold sections, each having a rigid housing and a thin, semi-rigid membrane removably and sealably mounted on the housing so as to define a fluid-tight chamber therein. The chamber of each mold section is filled with a noncompressible heat-conductive fluid to provide fluid backing to the portions of each membrane defining the molding surfaces of each mold section. A system of temperature control coils extending within each chamber are connected to an external heater/chiller unit to permit circulation therethrough of a suitable temperature control fluid, whereby positive control of the temperature of the backing fluid and, correlatively, the molding surfaces of the membranes.

摘要： A system is presented for training emergency personnel in the control, containment, and extinguishment of fires. The system includes an array of waterless burn plaques in selective communication with a pressurized source of combustible gas, such as propane. A flameless igniter is associated with each burn plaque, each flameless igniter igniting the combustible gas emitted from the associated burn plaque. When activated, the igniter is continuously operating, emitting electrical sparks across a gap between electrodes and operating substantially unaffected by its environment. Being waterless, the burn plaques are of a low profile and present minimal interference with trainees maneuvering thereabout.

摘要： A method of molding composite articles including arranging a pair of matched-tool mold sections in an opposed relationship, each mold section having a rigid housing and a thin, semi-rigid membrane removably and sealably mounted on the housing so as to define a fluid-tight chamber; filling the fluid-tight chambers with a non-compressible backing fluid; and accommodating thermal expansion of the backing fluid by an expansion chamber in fluid communication with the fluid tight chambers. The method further includes defining a mold plenum between the semi-rigid membranes when the mold sections are closed together; inserting reinforcement materials between the semi-rigid membranes prior to closing the mold sections; and injecting and curing a molding fluid after closing the mold sections. A step for regulating the temperature of the backing fluid may be included wherein a system of coils extend within each fluid tight chamber and wherein the coils are connected to an external heater/chiller unit and the coils are operative to circulate a temperature control fluid therethrough.
