A method for the production of stiffened components made of fiber-reinforced composite material using two rigid form tools which are suitable for covering the longer end sides of T-shaped preformed reinforcing fibers, using a folded hose core and inflation of the hose core so as to exert pressure on the end side of the preformed reinforcing fibers.

An assembly system includes a fixture configured to support a structure including at least one component to receive a malleable material, and a bladder system coupled to the fixture. The bladder system includes a hollowed frame having sidewalls that support a bladder disposed therein. The hollowed frame has an opening that exposes an outer portion of the bladder and is configured to guide the exposed outer portion externally from the hollowed frame toward a targeted area of the structure. In response to inflating the bladder, the outer portion of the bladder extends through the opening and applies a force against the at least one component so as to form a design feature element from the malleable material.

A composite part forming system for shaping a composite material blank having a plurality of plies, the composite part forming system comprising opposing tools including shape-forming features, an actuator, and a composite tensioning system. The composite tensioning system is connectable to a periphery of the composite material blank to apply tension to the composite material blank the first and second tools are moved together to cause the composite material blank to conform to the shape-forming features. The composite tensioning system is configured to apply more tension to wrinkle prone plies of the composite material blank than to non-wrinkle prone plies as the composite material blank is caused to conform to the shape-forming features.

Provided is an insulating coating device for an electric wire, including a pressing pipe. The pressing pipe includes two first pressing parts which are configured to divide the pressing pipe into two parts along a longitudinal cross section of the pressing pipe, an inner wall of the pressing pipe is provided with an air bag, and the air bag is provided with an air pipe joint which penetrates to an outside of the pressing pipe. In the insulating coating device for the electric wire, a self-curing insulating material is coated on joints of the electric wires, the air bag is used to squeeze the self-curing insulating material such that the self-curing insulating material is shaped and compacted, so that cavities generated in a coating process is reduced, and the self-curing insulating material is uniformly attached to the joints of the electric wires.

A material forming apparatus comprises: a support which is positioned at a side of a forming tool with respect to a material arranged on the forming tool to have a first part covered by the forming tool and a second part separated from the forming tool, and which supports the forming tool; a diaphragm which presses the second part of the material while the outer surface of the expanded diaphragm comes in close contact therewith, in a state in which the first part of the material is compressed by the forming tool and the outer surface of the diaphragm; and a volume-varying member which is disposed near the forming tool between the diaphragm and the support so that at least a portion thereof is positioned on the second part of the material.

A method of manufacturing a component by using a carbon fiber composite material capable of absorbing microwaves. The method includes the step of providing a mold made of materials that is penetrated by the microwaves and have a mold cavity inside, cladding the carbon fiber composite material on an inflatable member and placing the inflatable member cladded with the carbon fiber composite material in the mold cavity, softening the carbon fiber composite material by microwave heating, and inflating the softened carbon fiber composite materials through the inflatable member for enabling the softened carbon fiber composite materials to be formed and solidified in the mold cavity to obtain the component. By means of the aforesaid method, the throughput time of manufacturing the component can be effectively shortened.

A second stomp foot is movably connected to the carriage such that it may move along the vertical axis. A first swing arm is movably connected to the carriage and a second swing arm, movably connected to the carriage, is laterally opposed from the first swing arm relative to the longitudinal axis. A method includes applying at least one ply of composite material over a forming surface of a forming tool and deforming the at least one ply of composite material over the forming surface of the forming tool with the forming apparatus.

The disclosed forming apparatus includes a frame. The frame defines a vertical axis, a horizontal axis, and a longitudinal axis. A carriage is movably connected to the frame. A first stomp foot is movably connected to the carriage such that it may move along the vertical axis. A first end effector is movably connected to the carriage. The first end effector is controlled by an actuator. The disclosed method for forming a composite part includes applying at least one ply of composite material over a forming surface of a forming tool and deforming the at least one ply of composite material over the forming surface of the forming tool with a forming apparatus.

A bladder includes a first polymeric film, a second polymeric film attached to the first polymeric film to form a chamber, and one or more grooves formed in an exterior surface of the chamber. In one configuration, the grooves are formed in the exterior surface of the chamber by subjecting the chamber to a laser-etching process.

The present invention provide a forming method of forming a composition on a substrate using a mold, wherein the mold has a contact surface and a cavity, the method comprising: supplying a gas into the cavity so as to increase a pressure in the cavity to deform the contact surface into a convex shape toward the substrate; relatively tilting the mold with respect to the substrate; bringing the contact surface and the composition on the substrate into contact with each other in a state in which the contact surface has been deformed in the supplying the gas and the mold has been tilted in the relatively tilting; and further supplying the gas into the cavity so as to increase a deformation amount of the contact surface after the contact surface and the composition start to contact each other in the bringing.
