The use of natural fibers as reinforcement in polymeric matrix composites has been recently a promising field of study. The present work had, therefore, the objective to study a polyurethane derived from castor oil matrix reinforced with luffa fibers composites as a material to be used in panels such as Oriented Strand Boards (OSB). To do so, the luffa was cut to form a blanket and composite plates were made adding approximately 72% in mass in to the resin. The composites were subjected to flexural tests and the results shown an increase of about 20 times in the flexural strength and in 10 times in its elastic modulus in comparison with the pure resin, reaching 13.3MPa and 196.6 GPa for the flexural strength and modulus, respectively.
