摘要： A composite tube comprising a region of greater diameter forming a bellow. The bellow has a first side and a second side spaced apart in the axial direction of the tube. Each side of the bellow comprises at least one hole and the at least one hole on the first side is offset in relation to the at least one hole on the second side. The holes in the bellow provide increased flexibility, thereby allowing a greater amount of bending or articulation in the shaft. The holes reduce the amount of material in the sides of the bellow, thereby reducing the material stiffness and thereby increasing the flexibility.

摘要： A method and system for manufacturing composite parts free of wrinkles and mark-offs from bagging compression. The method can include placing composite material around a rigid mandrel and sealing opposing end of an elastomeric hollow membrane within a rigid external vessel. Then the method can include inflating the hollow membrane from a natural state to an inflated state. In the natural state, the hollow membrane can have a cross-section smaller than the cross section of the rigid mandrel with the composite material thereon. The method can then include inserting the rigid mandrel and the composite material into the membrane while it is in the inflated state, followed by releasing the membrane from the inflated state to naturally contract toward its natural state. Then the method can include heating the composite material to a cure temperature while the composite material is compressed by the membrane.

摘要： Described herein are methods and systems for forming composite stringer assemblies or, more specifically, for shaping composite charges while forming these stringer assemblies. A system comprises a bladder, having a bladder core, and a bladder skin. The bladder core is formed from foam. The bladder skin is formed from an elastic material and encloses the bladder core. When a composite stringer assembly is formed, the bladder is positioned over a charge base. The charge base later becomes a stringer base, such as a fuselage section or a wing skin. A charge hat is then positioned over the bladder and is conformed to the bladder. A combination of the bladder skin and the bladder core provides support during this forming operation and later while the stringer assembly is cured. In some examples, the bladder core is collapsible for the removal of the bladder from the cavity of the stringer assembly.

摘要： Lightweight and strong components may be manufactured using self-skinning foam material compositions by the processes described herein. One or more mandrels may be inserted into a molding tool, and a self-skinning foam material composition may be injected into the molding tool. After closing the molding tool, the self-skinning foam material composition may expand and cure to form a component, and one or more skins may be formed on exterior and/or interior surfaces of the component. For example, an external skin may be formed on an exterior surface of the component in contact with surfaces of the molding tool, and one or more internal skins may be formed on one or more interior surfaces of negative space spars of the component in contact with surfaces of the one or more mandrels.

摘要： Methods and apparatuses for electromagnetic support tooling for use in composite part curing are described. In one example, a support tooling, such as a mandrel, includes an elastomeric housing that has ferromagnetic components. The mandrel also has electro-magnetic coils positioned within the elastomeric housing and operable to generate magnetic fields to repel or attract the ferromagnetic components of the elastomeric housing to the electro-magnetic coils. When the ferromagnetic components of the elastomeric housing are repelled by the electro-magnetic coils, the elastomeric housing has a rigid surface state. When the ferromagnetic components of the elastomeric housing are attracted to the electro-magnetic coils, the elastomeric housing is collapsed.

摘要： A core system for the production of a fiber composite component includes at least two core elements which are coupled to one another and are displaceable relative to one another. At least one core element has a surface which is oblique to a displacement direction. A method for producing the fiber composite component uses the core system.

摘要： A method for forming a container assembly having a lid, a container and a cooperative closure mechanism, includes providing a lid form and flexible members biased toward the lid form, wherein the lid form and the flexible members are operable between a forming position defined by the lid form exerting a biasing force against the flexible members, and an extraction position defined by the biasing force being substantially removed from the flexible members, creating a lid form cavity defined by the lid form and the flexible members disposed in the forming position, injecting a lid material throughout the lid form cavity to form a lid, disposing the lid form and the flexible members in the extraction position, wherein the lid form is moved distal from the lid and the flexible members are biased away from the lid to separate the lid from the flexible members.

摘要： A plastic component, with fiber reinforcement, for use in a motor vehicle. The plastic component comprises a number of fiber layers connected to one another by injection of plastic and by a pressing force. The plastic component comprises at least two structural parts which overlap one another a pressing direction such that the die comprises at least one upper die portion formed with a pressing unit for applying a pressing force in the pressing direction, and at least one lower die portion which cooperates with the upper die portion to form a cavity in which the plastic component is formed. A die insert is fitted in the die and can move by and with the upper die portion and is designed to transmit the pressing force to the at least one structural part of the plastic component which is overlapped by the other structural part of the plastic component in the pressing direction.

摘要： A method for making a thermoplastic composite structure includes the steps of: (1) placing, in situ, fiber-reinforced thermoplastic material around a mandrel, wherein the mandrel includes a soluble material, (2) consolidating, in situ, the fiber-reinforced thermoplastic material to form a thermoplastic composite structure, and (3) at least partially solubilizing the mandrel from within the thermoplastic composite structure to remove the mandrel and provide the thermoplastic composite structure including a material thickness of the fiber-reinforced thermoplastic material, a structure shape, and a hollow interior.
