Paper HoneycombPhenolic impregnated Kraft paper fibre is fabricated to form a continuous series of triangular cells, similar in structure to the cross-sectional view of a corrugated box, creating a light but incredibly strong and rigid material and has outstanding properties, particularly shear modulus. The paper honeycomb is up to 95% open space, having a density of 54 kg/m3 (3.34 lb/ft3), but when bonded to a facing material on both sides, the resulting sandwich panel offers the highest rigidity and strength-to-weight ratio available. The fuzzy cell edge characteristic assures an excellent bond to face laminates. ATL Composites bonds timber or fibreglass veneers on either side of the honeycomb core to make Featherlight non-structural panels.
