摘要： An object of the invention is to provide a molding system and a production method for a composite molded body having excellent adhesion between carbon fiber and a thermoplastic resin and having a high degree of freedom in molding. The molding system includes: braiding means that braids a cylindrical material made of a composite material of carbon fiber and a thermoplastic resin; and warm pressure means that warm molds the braided cylindrical material into the composite molded body while pressuring the cylindrical material from the inside.

摘要： A composite door (100) comprises a composite frame (110), which comprises a first rail (111), a second rail (112), and crossbeams (113), joining the first rail (111) and the second rail (112). The composite door (100) also comprises a first composite side beam (130), a second composite side beam (140), and a composite skin (150), connected to each of the crossbeams (113) of the composite frame (110), to the first composite side beam (130), and to the second composite side beam (140). The composite door (100) further comprises first composite edge fittings (120), each connected to a corresponding one of the crossbeams (113) of the composite frame (110), to the first composite side beam (130), and to the composite skin (150), and second composite edge fittings (122), each connected to a corresponding one of the crossbeams (113) of the composite frame (110), to the second composite side beam (140), and to the composite skin (150).

摘要： Systems and methods are provided for facilitating pick and placement of preforms. One aspect is a method for picking and placing a preform. The method includes placing an inner surface of a first caul plate into contact with a first side of a stringer preform, such that an outer surface of the first caul plate forms a first plane that is uniform along a length of the stringer preform, placing an inner surface of a second caul plate into contact with a second side of the stringer preform, such that an outer surface of the second caul plate forms a second plane that is parallel to the first plane along a length of the stringer preform, grasping the caul plates at the first plane and the second plane along the length of the stringer preform, and lifting the stringer preform together with the caul plates while maintaining the grasp.

摘要： A composite panel tooling system (100) includes a forming platform (102) having a contoured surface (104) configured to support a layup of composite material to form a contoured composite part. The system further includes a flexible carrier (110) removably disposed on the contoured surface and comprising a frame, where the frame is configured to receive a set of double-sided vacuum grippers (402) within a set of apertures defined within the frame, and where each double-sided vacuum gripper of the set of double-sided vacuum grippers is configured to connect to a pneumatic system to induce a vacuum on a first side of each vacuum gripper for gripping the contoured surface and on a second side of each vacuum gripper for gripping a surface of the contoured composite part after the contoured composite part has been formed.
