Disclosed herein is a duplicator assembly for forming a first void, which can be layered, in a laminated material of a part that matches a second void in a scarf repair guide. The duplicator assembly comprises an arm that comprises a first end portion and a second end portion. The first end portion is spaced apart from the second end portion. The duplication assembly also comprises a probe that is fixed to the first end portion of the arm and configured to trace the second void in the scarf repair guide. The duplication assembly further comprises a milling tool that is fixed to the second end portion of the arm such that the milling tool is co-movably coupled with the probe via the arm.

A method for repairing a target member including a ceramic matrix composite reinforced by ceramic fiber includes: a removal step of removing at least a part of a surface of the target member; an arrangement step of arranging a green body for repair which includes the ceramic fiber on a portion where the surface is removed in the removal step; an impregnation step of impregnating at least the portion of the target member where the green body for repair is disposed with slurry; and a sintering step of sintering the target member on which the green body for repair is disposed, after the impregnation step.

A method of modifying or repairing a fluid conduit assembly includes scanning a sealing feature of a fluid conduit, the sealing feature including an abnormality, creating a 3D model of a sealing member configured to provide a fluid seal with the sealing feature, and utilizing the 3D model to form the sealing member via additive manufacturing. The method may include modifying the sealing feature of the fluid conduit to reduce or remove the abnormality and provide the sealing feature with modified dimensions. Scanning the sealing feature may include determining the modified dimensions of the sealing feature.

An applicator repair system for an additive manufacturing (AM) system, and an AM system including the same are disclosed. The applicator repair system includes a repair device including a repair element configured to repair a damaged applicator element on an applicator of an AM system. The damaged applicator element is configured to distribute a layer of raw material on a build platform of the AM system. The repair device is positioned within a processing chamber of the AM system. A damaged applicator controller may be provided that is configured to cause repair of the damaged active applicator in response to the damaged applicator being identified as damaged.

A method of repairing damage to a composite material having a composite substrate and at least one layer of shielding material includes: a) removing damage to the at least one layer of shielding material by creating a hole in the at least one layer of shielding material; b) applying a patch of shielding material in the region of the hole via a resin, wherein a ratio of a resin weight to a weight of the patch of shielding material lies in a range between about 0.45-0.55; and c) curing the resin, wherein an absorptive, consumable material is positioned in contact with the resin during at least a portion of the curing.

Disclosed herein is a method of repairing surface damage in an exterior surface of a hollow bladder, made of a cured elastomer. The method comprises placing first strips, made of an uncured elastomer, at least partially within the surface damage in the exterior surface of the hollow bladder in a side-by-side arrangement. The method also comprises sealing the surface damage, the first strips, and a portion of the exterior surface surrounding the surface damage in a vacuum bag. The method further comprises reducing pressure within the vacuum bag relative to outside the vacuum bag. The method additionally comprises while the pressure within the vacuum bag is reduced, heating the first strips from within the vacuum bag to cure the first strips.

Complex laminated composites may be repaired by removal of individual damaged plies through peeling in order to exploit the weaker interlaminar properties of these composites. Upon removal of the individual damaged plies through peeling, replacement plies may be added to restore the laminated composite. In addition, when damage extends through the thickness of a laminated composite, a plug may be used to allow plies to be replaced while maintaining contour within the repair region. A caul plate also may be used to stiffen and maintain the contour of a repair region while peeling and removing plies from the repair region.

A method for repair of a damaged stiffened panel of isogrid type, wherein the repair method comprises a step of removal of material with the aim of removing at least one damaged rib and also steps of fitting at least one structural reinforcement connecting at least two nodes positioned about the damaged zone and of at least one wall reinforcement connecting the wall of the stiffened panel and the structural reinforcement.

A first thermoplastic component and a second thermoplastic component including a first joint portion and a second joint portion, respectively, are provided. A least a portion of a surface area of each of the first and second joint portions include a respective first and second mating surface. The first and second mating surfaces of the respective first and second joint portions are positioned in contact with one another. The first and second joint portions are fusion joined. Fusion joining the first and second joint portions forms a fused unitary portion of the first and second thermoplastic components.
