1. A core-stiffened composite product comprising:

  • an interior core formed of a plurality of core components, each core component formed of a separate honeycomb structure, the core components being individually segmented and spaced apart;

    layers of composite laminates sandwiched together about the interior core; and

    at least one layer of adhesive film containing a visual target;

    wherein the visual target is configured to be 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 positioned to assure an as-designed alignment of each applied layer of laminate onto the interior core to minimize cumulative tolerance build-ups during a laminate layering process;

    wherein the at least one layer of adhesive film remains within the completed core-stiffened composite product; and

    wherein the core-stiffened composite product further includes exterior surfaces formed of layers of composite laminates, and the layers of composite laminates covering the adhesive film.
