摘要:
An area of a structure is reworked from one side of the structure using resin infusion of a dry fiber patch. Entrapped air and excess resin is removed from the patch during the infusion process by inserting a vacuum device into the patch, and forcing the area resin through the vacuum device.

A vacuum blanket (11) for covering a wind turbine component (12), wherein the vacuum blanket (11) comprises - At least one vacuum unit (113) for a vacuum assisted arranging (1511) of the vacuum blanket (11) and the wind turbine component (12); - At least one cross linking support device (114) for initiating and/or for supporting a cross linking of cross linkable adhesive which is arranged between the vacuum blanket (11) and the wind turbine component (12). In addition to the vacuum blanket (11), method for manufacturing an arrangement (1) of a vacuum blanket according to one of the claims 1 to 11 and a wind turbine component (12) with following steps: a) Applying of at least one precursor material (1312) of the adhesive material (1311) onto a component surface (121) of the wind turbine component (12); b) Bringing together the vacuum blanket (11) and the wind turbine component (12) such that the precursor material (1312) is enclosed by the vacuum blanket; and c) Transforming of the precursor material (1312) into the adhesive material (1311); wherein during the step b) and/or during the step c) an application of vacuum with the aid of the vacuum unit is carried out for a vacuum assisted arranging of the vacuum blanket and the wind turbine component. Preferably, a precursor material with at least one curable resin is used and the transforming comprises a temperature regulated curing of the resin. The wind turbine is preferably a wind turbine blade. With the vacuum blanket a safe repair of the wind turbine blade is possible.

Methods and apparatus for fabricating adhesive bonded joints while minimizing the voids and/or porosity found in the cured bondline. In accordance with various embodiments, the apparatus comprises an evacuation chamber combined with a pressure inducing device to produce bonded joints that are both void free and thoroughly compacted. The surfaces to be bonded are continuously evacuated throughout the bonding process (pre-mating, mating, debulking and cure). Continuous evacuation is provided via standard vacuum, while the induced pressure can be pneumatically or mechanically provided.

A kit for repairing an opening formed in a composite panel having a laminate skin arranged on opposing sides of a first core material is provided including a plug and a patch. The plug is formed from a second core material and has a cured filler material arranged within at least a portion of the second core material. The patch is formed from a plurality of cured first plies arranged in a stacked orientation. The plug is configured to be received within the opening of the composite panel and the patch is configured to cover the opening of the composite panel.

The invention includes methods and apparatus for preparing a tire surface for receiving a tire patch. Such methods include selecting a desired depth marking template for use in forming one or more depth marking apertures within a tire surface and within a desired tire patch application area, each of the one or more depth marking apertures having a desired depth corresponding to a desired depth of the patch receiving area, the template having one or more openings extending through a thickness of the template corresponding to the one or more marking apertures to be formed. The methods further include forming one or more depth marking apertures within the tread by inserting a material removal member of a power tool into each of the one or more openings in the template, the power tool removing tire material to the desired depth for each aperture.
