GRIDCORE TM (FPL Spaceboard) is a three-dimensional, pulp-molded sandwich panel made by depositing and densifying a pulp slurry on a specifically designed resilient mold. Unlike low density pulp-molded products, GRIDCORE TM panels can be highly densified to impart significant mechanical properties. This paper describes our initial efforts at producing GRIDCORE TM panels from blends of old corrugated containers (OCC), old newsprint (ONP), and kenaf. The panels were tested for edge crush strength, flat crush strength, bending strength, and dimensional stability. The results indicate that desirable mechanical properties can be achieved from all panel compositions.
