Systems and methods for actualizing simulated scarfing and patching for repair of composite laminates. A virtual environment is provided that enables engineers to optimize a repair design and provide the most robust repair solution that meets structural requirements, while minimizing the material removal and the impact to the composite structure. An optimization algorithm is configured to adjust contour offsets for pad-up plies and adjust scarf taper ratios in any direction to reduce the amount of material removed or avoid underlying structures. Scarf repair designs are subsequently transmitted to repair technicians for manual scarfing via printed templates or automated/robotic scarfing using converted computer-readable code. The technology also provides digital data for automated repair ply cutting.

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.

A method of repairing a composite beam having a longitudinal direction including: removing material from a damaged area of the composite beam to form a cut out region; machining a plurality of elongate slots into the composite beam, the elongate slots each having a length in the longitudinal direction of the composite beam and spanning across the damaged area, the elongate slots extending into the composite beam to a depth greater than a depth of the cut out region; introducing a plurality of reinforcing inserts into the respective elongate slots and fixing the reinforcing inserts into the slots with adhesive.

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.

In order to repair any damage to an originally applied paint film, a method of the invention facilitates repair of the paint film by removing essentially only that portion of the paint film that is damaged. After removal of the damaged portion of the paint film, a series of abrading, application, and polishing steps results in a repaired portion of the paint film.

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 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 ceramic matrix composite member including a ceramic matrix composite reinforced by ceramic fiber, includes a body portion and a joint portion joined integrally to the body portion, the joint portion occupying a part of a surface of the ceramic matrix composite member, wherein the body portion includes at least one hole extending toward an inside of the body portion from a boundary surface between the body portion and the joint portion, and the at least one hole is filled with a matrix of the ceramic matrix composite, wherein the body portion includes a first region where a density of the ceramic fiber is relatively high and a second region where the density of the ceramic fiber is lower than that in the first region, and wherein the at least one hole exists so as to cut off a part of bundles of the ceramic fiber in the second region.

Repair materials made of at least unvulcanized rubber are applied on a repair site of a damaged part of a tire, heating pads are applied on surfaces of the repair materials, wood pieces or other stuffing members differing in size are stuffed inside the tire, in a tire circumferential in tire circumferential direction where the repair materials are applied. The tire circumferential is fastened and pressed from surroundings by bands, and the repair site is heated by the heating pads to vulcanize the unvulcanized rubber of the repair materials, to thereby repair the tire. This repair method provides a low-cost tire repair method capable of maintaining the shape of the tire at the time of pressing and vulcanization, in various kinds of tires.

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.
