Delamination and crack prevention layer for structural sandwich panels
A method of manufacturing a delamination and crack prevention layer (DCPL) is provided for use in laminated sandwich panels. The DCPL is formed by using a continuous rolling process and by cutting finger profiles. Each finger forms a beam extending outward at a desired angle from a DCPL plane. The upper and lower DCPL planes are aligned to provide a uniform distribution of fingers along a length of the DCPL. Face sheets are bonded to the outer DCPL planes. Foam infusers add foam between the DCPL planes and among the fingers. The foam is rigidified (cured) during a continuous roll-form process. The DCPL prevents propagation of delamination between adjacent face sheets and core layers as well as arresting cracks in the core layers.
