Patent application number | Description | Published |
20090176066 | CONTOURED COMPOSITE PARTS - One embodiment of a composite part comprises a curved elongated section comprising a plurality of stacked reinforcement layers. The stacked reinforcement layers in the curved elongated section comprise at least one of non-continuous woven fabric and non-continuous reinforcement. | 07-09-2009 |
20090297358 | MODIFIED BLADE STIFFENER AND FABRICATION METHOD THEREFOR - The disclosure is generally directed to a modified blade stiffener having enhanced mechanical properties. An illustrative embodiment of the modified blade stiffener includes a stiffener-forming material shaped into a pair of coupled blades having first and second ends, a filler cavity provided at the first end of the blades, a blade filler provided in the filler cavity and a pair of blade flanges provided at the second end of the blades. | 12-03-2009 |
20100102482 | Method and Apparatus for Forming Highly Contoured Composite Parts - A method of forming a flat composite charge into a contoured composite part reduces wrinkles in the part as the charge is being formed. Dies are used to form a portion of charge to the steepest contour of the part, while tension is maintained on the charge as the remaining portions of the charge are formed. | 04-29-2010 |
20100140834 | Extrusion of Adhesives for Composite Structures - A structural filler is installed in a gap between at least first and second composite members by extruding a flowable filler material, placing the extruded filler on one of the composite structural members, and assembling the composite members. | 06-10-2010 |
20110146906 | Double Vacuum Cure Processing of Composite Parts - Out-of-autoclave curing of a composite part is performed using a double vacuum chamber assembly comprising integrated inner and outer vacuum chambers. | 06-23-2011 |
20120171410 | CONTOURED COMPOSITE PARTS - One embodiment of a composite part comprises a curved elongated section comprising a plurality of stacked reinforcement layers. The stacked reinforcement layers in the curved elongated section comprise at least one of non-continuous woven fabric and non-continuous reinforcement. | 07-05-2012 |
20120261059 | EXTRUSION OF ADHESIVES FOR COMPOSITE STRUCTURES - A structural filler is installed in a gap between at least first and second composite members by extruding a flowable filler material, placing the extruded filler on one of the composite structural members, and assembling the composite members. | 10-18-2012 |
20120298296 | VACUUM BAG PROCESSING USING DUAL SEALS - Apparatus for processing a workpiece comprises a base adapted to have a workpiece placed thereon. A vacuum bag is placed over the workpiece, and the bag is sealed to the base using inner and outer seals. The inner and outer seals are spaced apart from each other to form a channel therebetween. A vacuum port coupled with a vacuum source is used to evacuate air from the channel. | 11-29-2012 |
20140037780 | FORMING HIGHLY CONTOURED COMPOSITE PARTS - A method of forming a flat composite charge into a contoured composite part reduces wrinkles in the part as the charge is being formed. Dies are used to form a portion of charge to the steepest contour of the part, while tension is maintained on the charge as the remaining portions of the charge are formed. | 02-06-2014 |
