摘要： A method and apparatus for processing measurements of an acoustic wave, the acoustic wave being within a member (12) made of a composite material and caused by an impact to the member (12), the method comprising: analyzing the measurements to detect an initial acoustic wave feature; analyzing the measurements to detect the presence of further acoustic wave features, the further features occurring after the initial feature; if there are no further acoustic wave features, determining that the impact to the member (12) has not changed the structure of the member (12); if there are further features, determining a value of a function of the further acoustic wave features; if the determined value satisfies certain criteria, determining that the impact has changed the structure of the member (12); and if the determined value does not satisfy the criteria, determining that the impact has not changed the structure of the member (12). By doing so, impact induced damage is detected and quantified by processing separately acoustic data generated by the impact from acoustic data generated by acoustic emission due to damage generation.

摘要： There is provided apparatus and a method for assessing the integrity of a bonded joint and a bonded joint assembly. The assembly has a bonded joint monitored for bond integrity and comprises first (1) and second (2) components each defining a bonding surface (3,4); the joint (5) is formed between the bonding surfaces (3,4) and the first component (1) defines a passage (15) therethrough from the bonding surface to an exterior of the component. The joint (5) includes an optical fibre (11) extending along the joint (5) between the bonding surfaces, through the passage (15) and emerging from the passage (15) to the exterior of the component. The method of constructing the assembly includes the steps of passing the optical fibre (11) through the passage (15) and adhering the optical fibre (11) to the bonding surface (3) of the first component (1), thus bringing the two bonding surfaces (3,4) together and forming the bond (5).
