Abstract

This study investigated the effects of production variables on physical and strength properties of air-formed OCC fibers / polymer composites. A combination of 12  treatments of OCC fibers and coupling agents for air-forming were investigated. Physical and mechanical properties of the sample were analyzed using factorial experimental design with completely randomized and DMRT test is used to classified the averages. The results of this study showed that addition of 70% OCC fibers to the polymers in air forming resulted in composites with higher strengths and modulus of rupture and 55% OCC fibers increased internal bonding, tensile strength and modulus, and lowered thickness swelling. Thickness swelling after 2 h water-soak and mechanical properties were improved by addition 2 and 4 % coupling agent
