Abstract

A composite composition includes a thermoset resin and about 3 wt. % to about 35 wt. % of at least one material selected from the group consisting of cellulose nanofibrils (CNF), micro-sized cellulose fibers (MFC), and cellulose nanocrystals (CNC) dispersed therein as measured with respect to the overall weight of the composite composition. The cellulose nanofibrils and/or nanocrystals have an average diameter of about 5 nm to about 500 nm and an average aspect ratio in the range of about 5:1 to about 500:1. The cellulose micro-sized fibers have an average diameter of about 5 μm to about 100 μm and an average aspect ratio in the range of about 5:1 to about 250:1.
