    摘要: Method and a tool component for forming in an article of fiber-reinforced composite material at least one locally placed, sharply curved portion (12). A separate, substantially rigid pressure-transferring element (20) configured with a profile corresponding to said at least one curved portion (12) is placed over the laminate (18) at the location of the at least one locally placed, sharply curved portion (12) of the mold surface, and a flexible membrane (28) placed over the laminate (18) and over outer, separated surfaces (24, 26) of the pressure-transferring element (20) is evacuated to depress the laminate (18) to fully conform to the shape of the mold surface.

    摘要: The present invention relates to a forming device (1) and a method of manufacture of a fillet (17) of plastic for aircraft assemblies or the like, said fillet (17) having a predetermined profile (9) for filling a cavity (61) of a structural element (59), the fillet (17) being formed using a forming means (29) of a forming device (1). The method comprises the steps of applying at least one blank of a base material (15) of plastic between at least two opposed press beds (5) of the forming means (29) and at least one of said press beds (5) comprising elongated grooves (7); moving at least one press bed (5) towards the other press bed, until the press beds (5) are in position for completed compression of the fillet (17), wherein each groove (7) for forming of the fillet (17) generates a fillet (17) in correspondence with said pre-determined profile (9); separating the press beds (5) from each other for releasing the formed fillets (17); removing the formed fillets (17) from the forming means (29); and applying the formed fillets (17) in the cavity (61).

    摘要: Method for repairing a damaged or defective part (2) of a composite or sheet-like article (1). The method comprises the steps of placing a repair patch (3) over the damaged or defective part of the article, locating a pressure chamber including moulding tool means (7) over at least the damaged or defective part (2) of the article (1) and curing. The method comprises the further step of applying a viscous material (5) in the vicinity of the damaged or defective part (2) of the article (1) before curing and heating the viscous material (5) so that it becomes less viscous and flows into any undesired gaps between the moulding tool means (7) and the article (1).
