Abstract: A toughened polyester composite comprising: (i) a polyester matrix and (ii) droplets of a high boiling point liquid having a boiling point of at least 140° C. dispersed in said polyester matrix, wherein the high boiling point liquid is present in an amount of 0.1-10 wt % by weight of the toughened polyester composite, and wherein the composite may further include: (iii) a modifier selected from polycarboxylic, polyol, and polyamine compounds, wherein the modifier is present in an amount of 0.1-10 wt % by weight of the toughened polyester composite. Methods for producing the polyester composite are also described.

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 ?m to about 100 ?m and an average aspect ratio in the range of about 5:1 to about 250:1.
