摘要: Non-destructive evaluation (NDE) systems and methods are provided for monitoring objects being manufactured during a cure or consolidation process and for detecting defects that occur during the cure or consolidation process or to detect conditions of the process that can lead to the occurrence of defects. Information acquired by the NDE system during the cure or consolidation process can be used to adjust one or more parameters of the process in real-time to prevent defects from occurring or to reduce the number and/or severity of defects that occur during the cure or consolidation process.

摘要: Systems, methods, and devices of the various embodiments may enable simultaneous preparation of a substrate for adhesive bonding and detection of minute contaminants on the substrate. Various embodiments may enable detection of contaminants on a surface of a substrate while the surface of the substrate is being prepared for adhesive bonding by laser ablation. Various embodiments may provide an integrated laser treatment and measurement system.

摘要: A method for bonding composite substrates includes coupling a first co-cure prepreg layer having a first off-set amine to epoxide molar ratio onto a surface of a first composite substrate and coupling a second co-cure prepreg layer having a second off-set amine to epoxide molar ratio onto a surface of a second composite substrate. The first and second composite substrates are cured to the first and second co-cure prepreg layers, respectively, using a first cure cycle (including B-stage and cure temperatures) to form a first and a second co-cure prepreg layer portion. The method further includes coupling the first co-cure prepreg layer portion to the second co-cure prepreg layer portion and applying a second cure cycle to cure the first co-cure prepreg layer portion of the first composite substrate to the second co-cure prepreg layer portion of the second composite substrate to form a monolithic covalently bonded composite structure.

摘要: System and method for in-process cure monitoring of a material utilizes one or more sensors such as fiber Bragg gratings (FBGs) or phase-shifted FBGs (PS-FBGs) and at least one optical line fiber connected to the sensor(s). The sensor(s) and the optical line may be embedded in the material prior to curing the material may comprise a fiber reinforced polymer. Waves are excited into the material during curing thereof to form guided waves that propagate through the material. At least one wave metric of the guided waves is measured utilizing the sensor(s).
