A material for use in vacuum bagging a component. The material includes a compound sensitive to moisture, such that an exposure of the compound to moisture or wetting causes a physical and/or chemical change in the compound that is visually detectable in the cover material. A method of leak detection during vacuum bagging involves the steps of: arranging a component in a vacuum bagging assembly, such as to form a fibre-reinforced plastic component; arranging a material according to the invention in the vacuum bagging assembly such that the compound sensitive to wetting or moisture is under, or on an inner side of, a sealing film or vacuum bag of the assembly; applying a vacuum to the vacuum bagging assembly to evacuate a space containing the component and sealed by the sealing film or vacuum bag; and wetting an outer surface of the sealing film or vacuum bag. |
