An intensifier mechanism for forming stacked material includes a support, a first body coupled to the support, and a second body having a main portion, a pivoting portion, and a joint. The main portion is coupled to the support and the joint movably couples the main portion to the pivoting portion. The joint allows the pivoting portion to pivot in relation to the main portion when the membrane moves towards the bottom wall.

A method of removing a vacuum bag from a composite mold. Removable strips are placed around the perimeter of the component parts and across the parts to create natural break points in the consumable materials used during manufacture of a composite product, e.g. wind turbine blade. The vacuum bag, and other consumable layers, are placed over the removable strip such that when the strips are pulled, the strip tears, in a controlled and complete manner, through each layer of consumables. This eliminates the need to use a knife/scissor to remove the finished product, thereby avoiding risk of injury.

An apparatus for thermally joining thermoplastic fiber composite components includes a pressurization arrangement for jointly covering, at least in a region of a joining zone, thermoplastic fiber composite components to be joined and applying pressure to the thermoplastic fiber composite components to press the thermoplastic fiber composite components against one another, at least in the joining zone, the pressurization arrangement being flexible, at least in some section or sections. A welding device is configured for welding the fiber composite components in the joining zone during pressurization. The pressurization arrangement and welding device are configured to weld the thermoplastic fiber composite components in a pressurized state in the joining zone. The pressurization arrangement is configured to maintain pressurization independently of the welding device until the joining zone solidifies. A cover is also disclosed for a pressurization device for thermally joining thermoplastic fiber composite components.

Thermal curing of a potting material within a hole in a surface of a composite material is described utilizing a flexible vacuum compression device that includes a chemical-based heating pack. The vacuum compression device includes an internal compartment within a cavity that retains the chemical-based heating pack, and a vacuum port having a passage into the cavity. An end of the vacuum compression device includes an interface that forms an air-tight seal between the cavity and the surface when applied to a surface of the composite material. Drawing a vacuum via the vacuum port collapses the vacuum compression device and positions the chemical-based heating pack proximate to the surface, enabling heat from the chemical-based heating pack to thermally cure the potting material.

Systems and methods are provided for utilizing pellet-loaded bladders to consolidate and/or harden composite parts. One embodiment is a method for fabricating a composite part. The method includes laying up a preform that is made of fiber reinforced material and that includes a cavity, inserting one or more bladders that are loaded with expandable pellets into the cavity, inflating the bladders in response to a triggering condition, consolidating the preform while the bladders are inflated, deflating the bladders, and removing the bladders from the cavity.

A method for molding a laminated body includes laminating a reinforced fiber base material on a molding surface of a molding jig to form a laminated body; attaching a pulling jig to a third lamination portion of the laminated body; forming a protrusive curvature part and a recessed curvature part in the laminated body by curving the laminated body along a protrusive curvature surface and a recessed curvature surface formed on the molding surface while pulling the end of the laminated body with the pulling jig; and densifying the laminated body by heating the curved laminated body while pressurizing the same. The reinforced fiber base material is laminated so that at least a part of a gap between layers of the reinforced fiber base material becomes a non-adhered state in a portion from the protrusive curvature part to the third lamination portion formed in the laminated body.

A method for manufacturing a part layer-upon-layer using Additive Manufacturing technology, the method including: printing the part together with an elastomeric enclosure shaped thereto leaving a gap free of material therebetween, the elastomeric enclosure including at least one opening; heating the ensemble of the printed part and elastomeric enclosure or keeping an operating printing temperature; applying vacuum by the at least one opening of the elastomeric enclosure so that the elastomeric enclosure deflates thus exerting pressure to the printed part; and maintaining the printed part under vacuum and heat during a predefined time.

A method for thermally joining thermoplastic fiber composite components, including jointly covering thermoplastic fiber composite components to be joined, at least in the region of a joining zone, with a pressurization arrangement, which is flexible, at least in some section or sections, and extensive pressurization of thermoplastic fiber composite components to be joined by the pressurization arrangement, with the result that the fiber composite components are pressed against one another, at least in the joining zone. The fiber composite components are welded in the joining zone during pressurization. The pressurization is maintained by the pressurization arrangement until the joining zone solidifies. A cover is also disclosed, in particular a mold or diaphragm, for a pressurization device for thermally joining thermoplastic fiber composite components, and an apparatus for thermally joining thermoplastic fiber composite components.
