The Ob jective of this work was to evaluate the mechanical properties: modulus of rupture (MOR), tensile strength in perpendicular direction (TP) and tensile strength in surface direction (TS) of Mediu m Density Fiberboards (MDF) manufactured with polyurethane resin prepared with castor oil (PU Castor Oil) and fibers of Pinus elliottii wood. To the essay characterizat ion was used the European Standard EM B/IS-2:1995, and was prepared fiberboards with 500×500 mm and two thickness (8mm and 15
