A forming device and a method of manufacture of a fillet of plastic for aircraft assemblies. The fillet has a pre-determined profile for filling a cavity of a structural element. The fillet is formed using a former of a forming device. The method includes applying at least one blank of a base material of plastic between at least two opposed press beds of the former and at least one of the press beds including an elongated groove. At least one press bed is towards another press bed, until the press beds are in position for completed compression of the fillet. Each groove for forming of the fillet generates a fillet in correspondence with the pre-determined profile. The press beds are separated from each other for releasing the formed fillet. The formed fillet is removed from the former. The formed fillet is applied in the cavity.

Method of manufacture of fillets for aircraft assemblies or the like and a forming device

A method for producing an object of composite material comprising the steps of:

Manufacturing method for trumpet spar and other curved objects

The present invention relates to a method for the manufacture of a composite article comprising a composite plate () and at least one fitting (). The method is characterized by the steps of arranging at least one former on said composite plate (), arranging at least one fitting () on said composite plate (), producing a lay-up by applying a composite material layer () least partly covering an external surface of the former and of the fitting, and curing the layup in a curing process. After curing, said composite material layer () forms the walls of a stiffener and at least partly encloses the fitting so as to support it in a predetermined position.

Method for the manufacture of a composite article

A method for manufacturing a hollow load-bearing beam structure of fiber-reinforced composite material. The method includes preparing a first lay-up of a first plurality of layers, and a second lay-up of a second plurality of layers. The first and second lay-ups are positioned on different sides of a mandrel and formed to a beam structure by bending the lay-ups against the mandrel, such that the side edges of the respective layers of the first and second lay-ups are arranged as offset butt joints in the circumferential direction of the formed beam structure.

Method for manufacturing beams of fiber-reinforced composite material

In a method and a tool for forming an elongate, hollow article of a fiber-reinforced composite material one end of an article laminate applied to a tool bar is placed in engagement with or is supported by an anvil of the tool so as to control the direction of longitudinal movement of the cured article relative to the tool bar during the cooling and dismantling phase.

Method and tool for forming an elongate, hollow article of a fiber-reinforced composite material

A helical tool (&#x2033;) having a rigid outer helical support surface () is used as support for a non-rigid material for producing a hollow elongated member onto and as an integral part with a surface member () in manufacturing of a surface member having at least one hollow elongated stiffening member integral therewith.

Use of a tool and a method for producing a surface member

A method and a tool component for forming in an article of fiber-reinforced composite material at least one locally placed, sharply curved portion. A separate, substantially rigid pressure-transferring element configured with a profile corresponding to the at least one curved portion is placed over the laminate at the location of the at least one locally placed, sharply curved portion of the mold surface. A flexible membrane placed over the laminate and over outer, separated surfaces of the pressure-transferring element is evacuated to depress the laminate to fully conform to the shape of the mold surface.

Method of manufacturing an article of fiber-reinforced composite material

The invention refers to a plant and a holding device in connection with heat treatment of articles ( ), which is at least partly manufactured in a thermosetting composite material. The holding device, which is comprised by the plant, includes a base element ( ), and intermediate element ( ), which rests on the base element ( ), and at least a support member ( ), which is fixable to the intermediate element ( ) and arranged to support said article ( ) on the intermediate element during the heat treatment. The intermediate element ( ) is manufactured in a material which has a neglectable thermal extension at least up to a temperature level, at which the heat treatment is intended to take place. Furthermore, the intermediate element ( ) is displaceably positioned on the base element ( ).
