Resumo

Abstract This work compares the dynamic mechanical behavior of piassava fiber–reinforced polyester composites with the behavior of the neat resin matrix. The results obtained confirm previous data showing that the interface of piassava/polyester composites is stronger than the usual interfaces found when untreated lignocellulosic fibers are incorporated into common polyester matrices. This behavior was attributed to silica-rich protrusions found at the fibers' surface that aid to anchor the resin matrix and increase the stress transfer at the fiber–matrix interface. Keywords: dynamic mechanical analysisfiber-reinforced compositesinterfacespiassava fibers This work was supported by the Brazilian Agency CNPq. Notes ∗The authors suggest that the interfacial shear strength is only frictional.
