Abstract: The aim of this work is to evaluate the influence of the sugar cane bagasse NaOH treatment in the mechanical and dynamic-mechanical properties, in the thermal stability, density and water absorption, when used in unsaturated polyester resin/sugar cane bagasse composite. The sugar cane bagasse was submitted to the chemical treatment with alkaline solution of NaOH. The treatment improves the impact and flexural elasticity modulus when compared with resin without fibers, in addition to the adhesion of the fibers with the matrices, but does not improve significantly the tensile elasticity modulus. The surfaces of the impact fracture were analyzed by SEM.
