Abstract
The interest for the use of vegetal fibers as polymer reinforcement has recently increased because of their unique environmental and technological advantages. The aim of this research is to evaluate the feasibility of using Curauá (Ananas erectifolius) fibers as natural reinforcement of polymer mortars with particular regards to fracture and toughening mechanisms. Various weight fractions of aggregate 1%, 2%, 5% and 10% were replaced by the same weight of curauá fibers. A significant reduction of the specific weight of the polymer mortars and an improvement of their post-peak flexural behavior followed by less brittle failure was observed.
