20130209601PROCESSES AND SYSTEMS FOR MANUFACTURING SPARS AND OTHER HOLLOW STRUCTURES - Processes for manufacturing hollow structures such as spars for helicopter rotor blades, fixed wings for aircraft, and other aerostructures can include the provision of a path for gases to exit the material from which the spar is formed as the material is heated and cured, to help eliminate voids within the material caused by the presence of such gases.08-15-2013
20120308681Intelligent Slitting - A system for managing elongation and stress dispersal in a bladder used during a deep draw high pressure process. Resilient bladder material is slitted at concentric or peripheral intervals from the bladder edge(s). The slits above are offset from slits below, such that as the bladder is stretched with deformational forces, the slits are widened, and as deformation forces are abated or relieved, the bladder and its slitting reassume their pre-deformation configurations.12-06-2012
20110027405Corner-Consolidating Inflatable Method for Manufacturing Composite Structures - An inflatable compaction tool for consolidating a composite material inside a faceted hollow or tubular mold for a composite part is made from an elastic material. The compaction tool includes relatively flat wall segments conjoined by corner segments that define a sealed chamber. The wall segments curve away from the mold surface toward the midpoint of each wall segment, so that as a pressurized fluid is introduced into the compaction tool, a component of the force exerted on the tool interior surface is transmitted through the wall segments toward the corner segments. Thus, during initial inflation, the corner segments are forced toward the corner regions of the mold before the wall segments contact the composite material, firmly compressing the composite material into the corner regions of the mold before the friction of the wall segments against the composite material inhibits expansion of the corner segments into the mold corner regions.02-03-2011
20120135099METHOD AND APPARATUS FOR RAPID MOLDING OF WIND TURBINE BLADES - A compliant cover is placed over a part being molded in a molding process. The compliant cover is formed from a plurality of longitudinal cells positioned next to one another. At least one communication port is coupled to each longitudinal cell, and a source of fluid media at a preselected temperature is coupled to the communication ports whereby the longitudinal cells may be filled with the fluid media at the preselected temperature. The compliant cover may thus be used to selectively heat and cool the part being molded to decrease the time required by the part to rise to the temperature required to cure the resin in the part and to cool the part so that it can be removed from the mold.05-31-2012
