Abstract

This study aims to evaluate plant fibers that were surface activated with NaOH and corona discharge before incorporating in ortho unsaturated polyester-based fiber composites. It demonstrates the potential use of lignocellulosic particles, especially eucalyptus that presented the higher values for all the mechanical properties analyzed. The corona discharge treatment increased impact strength and tensile strength of the composites, and decreased water absorption. SEM images showed that the surface activation generally improved the interfacial adhesion between fibers and polyester matrix. Corona treatment may depolymerize the lignocellulosic material and smaller fragments may actually help increase the interaction with the polyester.
