Fibre-Metal Laminates (FMLs) are hybrid materials that consist of thin layers of metal and fibre-reinforced polymer, and have already been applied several aircraft. It is well-known that there is a difficulty in non-destructive assessment of damage in FMLs using laboratory radiography or X-ray computed tomography since FMLs have laminate structure of materials with different X-ray absorption coefficient. Synchrotron radiation laminography at SPring-8 in Japan is employed to assess low velocity impact damage in CFRP/Ti laminates as FMLs. It is verified that how each damage mode, such as crack in titanium layer, fibre break, matrix cracking, interlaminar delamination in CFRP layers and interfacial debonding between CFRP and titanium layers, can be observed in obtained reconstructed slice images. Three-dimensional imaging of the low velocity impact damage is also demonstrated by stacking the reconstructed slice images, and that is to our knowledge a novel result.

Carbon fiber reinforced plastic is a resin-based composite material reinforced with carbon fiber, which is a high-performance fiber having features such as light weight, high strength, and high rigidity. CFRTP using a thermoplastic resin has a short molding time and is excellent in economy, and the thermoplastic resin melts when heat is applied, so that it can be recycled. On the other hand, CFRP and CFRTP are known as difficult-to-process materials that are difficult to process, and in laser processing, a heat-affected region is generated in which the resin evaporates and carbon fibers are exposed when irradiated with a laser. Since there is a concern that this heat-affected zone will reduce the strength of CFRP and CFRTP, it has become an important issue in recent years to find processing conditions that keep this heat-affected zone small. Search for conditions.
