摘要： Systems and methods provide for the determination and correction of tooling deviation by comparing two different three-dimensional surface scans of a composite panel after curing. Such methods and systems may allow for less accurate post-cure fixturing (e.g., holding the panel in a less constrained state, as compared to prior art techniques), while still maintaining a sufficient amount of precision for predictive shimming and shimless techniques. Methods include performing a first three-dimensional surface scan, performing a second three-dimensional surface scan, and comparing the two to determine a deformation function corresponding to tooling deviation. In some systems, a header structure is used to hold the composite panel in a nominal configuration for the second three-dimensional surface scan. In some systems, scanning devices perform mirrored scanning on either side of the composite panel, using a common reference frame.

摘要： A composite structure that includes a multi-layer laminate including a plurality of layers of material, and at least one crack barrier layer extending within the plurality of layers of material. The multi-layer laminate is folded to define a first web region and a second web region in a face-to-face relationship, and a folded tip region defined between the first web region and the second web region. The at least one crack barrier layer is configured to restrict crack propagation from spreading through the plurality of layers of material in the folded tip region.

摘要： A method for manufacturing a panel including a reinforcement sheet (6) comprises the steps of: providing a first layer (3) of thermoplastic material, providing a reinforcement sheet (6), laying the reinforcement sheet (6) and the first layer (3) onto each other, applying a second layer (11) of thermoplastic material on top of the reinforcement sheet (6) at a side facing away from the first layer (3), at least partially melting the thermoplastic materials of the first layer (3) and the second layer (11), adhering the at least partially melted first layer (3), the at least partially melted second layer (11) and the reinforcement sheet (6) to each other so as to form the panel, wherein the reinforcement sheet (6) and the first layer (3) are adhered to each other by pressing them together after at least partially melting the thermoplastic material of the first layer (3), but before applying the second layer (11) of thermoplastic material onto the reinforcement sheet (6).
