Patent application number | Description | Published |
20090148647 | Method of Fabricating Structures Using Composite Modules and Structures Made Thereby - A large scale composite structure is fabricated by forming a plurality of composite laminate modules and joining the modules together along their edges using scarf joints. | 06-11-2009 |
20100078126 | Compaction of Prepreg Plies on Composite Laminate Structures - A flexible compaction sheet is used to compact uncured composite plies onto the surface of a ply layup. The compaction sheet includes a peripheral seal that seals the perimeter of the sheet to the surface of the part layup and forms a vacuum chamber over the plies which is evacuated through the sheet to apply compaction pressure to the plies. | 04-01-2010 |
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 |
20100154990 | COMPOSITE STIFFENER POSITIONING AND VACUUM BAG INSTALLATION DEVICE - A method and apparatus for manufacturing composite parts. An expandable tool with a transfer system may be moved on a surface of the expandable tool into an outer mold line tool with a composite material laid up on the outer mold line tool. The expandable tool may be expanded in the outer mold line tool to change the surface from a retracted state to an expanded state. The transfer system may be transferred from the expandable tool with the surface in the expanded state to the outer mold line tool. | 06-24-2010 |
20100155984 | MANUFACTURING ONE-PIECE COMPOSITE SECTIONS USING OUTER MOLD LINE TOOLING - A method for manufacturing composite parts. A temporary removal layer may be placed on an inner mold line tool. A composite material may be laid up on the inner mold line tool for a composite part. The inner mold line tool may be positioned with the composite part inside an outer mold line tool. The composite part and the temporary removal layer may be transferred from the inner mold line tool to the outer mold line tool. The inner mold line tool and the temporary removal layer may be removed from inside of the outer mold line tool after transferring the composite part and the temporary removal layer to the outer mold line tool. | 06-24-2010 |
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 |
20130042978 | Compaction of Prepreg Plies on Composite Laminate Structures - A flexible compaction sheet is used to compact uncured composite plies onto the surface of a ply layup. The compaction sheet includes a peripheral seal that seals the perimeter of the sheet to the surface of the part layup and forms a vacuum chamber over the plies which is evacuated through the sheet to apply compaction pressure to the plies. | 02-21-2013 |
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 |
