Abstract

A method of repairing damage to a composite material (12) comprising a composite substrate (14) and at least one layer of shielding material (16). The method comprises the following steps: a) removingdamage to the at least one layer of shielding material (16) by creating a hole (20) in the at least one layer of shielding material; b) applying a patch (28, 32) 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 (42) is positioned in contact with the resin during at least a portion of the curing.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority to UK Patent Application No. 1516391.8, filed 16 September 2015. technical field [0003] The present invention relates to one or more methods of repairing a composite material by applying a shielding material (eg, an expanded foil layer, such as a copper foil layer) to the composite material. Additionally, the present invention relates to one or more methods for repairing layers of shielding material commonly incorporated into composite materials used to build aircraft. The invention also includes the resulting restoration. Background technique [0004] It should be apparent to those skilled in the art of building aircraft from composite materials that there are areas on the aircraft, particularly on the skin of the aircraft, where shielding material is embedded in the skin of the aircraft. [0005] Since the composite material is not particularly conductive, the shielding mat...
