Spatial reference film in core-stiffened composite

Abstract:

A core-stiffened composite product has an interior core and layers of composite laminates sandwiched together about the core. The core-stiffened composite product includes at least one layer of adhesive film containing a visual target spatially scanned by an automated tracking system to produce a dimensionally corrected reference volume to collate successive layers of film as applied to the interior core. The visual target is positioned to assure an as-designed alignment of each applied layer of laminate onto the core to minimize cumulative tolerance build-ups during a laminate layering process. At least one layer of adhesive film remains within the completed composite product.
