ABSTRACT
GRIDCORETM (FPL Spaceboard) is a three-dimensional, pulpmolded
sandwich panel made by depositing and densifying a
pulp slurry on a specifically designed resilient mold. Unlike
low density pulp-molded products, GRIDCORETM panels can
be highly densified to impart significant mechanical properties.
This paper describes our initial efforts at producing
GRIDCORETM 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.
