A method for fabricating a repair laminate for a composite part having an exposed surface includes applying a release film to the exposed surface and forming an uncured ply stack assembly on the release film. The uncured ply stack assembly is formed by forming and compacting a series of uncured ply stacks. The release film and ply stack assembly is then removed from the exposed surface. A bonding material is then applied to the exposed surface, and the uncured ply stack assembly is applied to the bonding material. The ply stack assembly and bonding material are then cured.

Multi-stage debulk and compaction of thick composite repair laminates

A method for repairing damage to a composite part includes creating an aperture through the composite part and preparing the surfaces surrounding the aperture on both sides of the part; inserting a plurality of resin impregnated fibers through the aperture and spreading the end portions of the plurality of fibers radially against the prepared surfaces on both sides of the part; and maintaining contact of the plurality of fibers with the prepared surfaces while the resin cures.

Method for repairing a composite part

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.

Processes for repairing complex laminating composites

Processes for repairing complex laminated composites

An apparatus and method for repairing a damaged laminate including the process of cutting out a damaged section and replacing damaged section with a repair laminate, then covering the repair laminate with a vacuum bag having a heater disposed therein. Thereafter, applying heat and pressure to the repair laminate with the heater and vacuum bag to adequately debulk and cure the repair laminate.

Single stage debulk and cure of a prepreg material

A device and method for applying treatment to a structure includes a housing having a first membrane sealed to a second membrane for creating an airtight cavity therebetween for receiving a porous material and a working layer. The method includes the process of conforming the shape of the housing to the structure and applying a treatment thereafter to the structure.

Vacuum assisted conformal shape setting device

A method for fabricating a repair laminate for a composite part having an exposed surface includes applying a bonding material to the exposed surface and forming an uncured ply stack assembly on the bonding material. The uncured ply stack assembly is formed by forming and compacting a series of uncured ply stacks. The ply stack assembly and bonding material are then cured.

In-situ, multi-stage debulk, compaction, and single stage curing of thick composite repair laminates

A method of attaching a composite member to a structure. The method including forming a laminate of fabric impregnated with resin; applying heat at a first temperature to the impregnated laminate; applying vacuum at a first pressure to the impregnated laminate to degas the resin and form a degassed, impregnated laminate; positioning the degassed, impregnated laminate on a structure; and curing the degassed, impregnated laminate on the substrate by applying heat at a second temperature and by applying vacuum at a second pressure.

Single vacuum debulk composite panel repair

A device and method to repair a structural component. The device includes a plug that bonds to the structural component. The plug includes a flange and a solid shank extending from the flange, the solid shank being disposable in an opening of the structural component. The device further includes disc that bonds to the structural component such that, when bonded, the disc covers the solid shank of the plug. The method includes bonding the plug to the structural component such that the solid shank of the plug is disposed in the opening of the structural component. The method further includes bonding the disc to the structural component.
