PROPERTIES OF POLYISOCYANATE RESIN CONSOLIDATED COMPOSITES MADE FROM SECONDARY FIBERS OF CORRUGATED CONTAINERS

This study examined the properties of composites made from secondary f ibers from old corrugated containers (OCC). A polyisocyanate resin was used to consolidate the OCC fiber composites with a dry manufacturing process. The properties of the OCC fiber composites were compared to the properties of fiber composites made from virgin aspen that were th ermal-mechanically pulped (TMP). Generally, all OCC fiber composite pr operties were determined to be inferior to those of virgin aspen TMP f ibers. A literature review is also presented that provides possible ca uses for the inferior quality of OCC fiber composites.
