The growing demand for panels of Medium Density Fiberboard (MDF) for manufacture of furniture produces significant quantities of waste, which is often inappropriate discarded. This paper presents the study of the characterization of a polymeric matrix composite reinforced with powdered MDF residues collected from cuts machines for furniture manufacturing. Samples of the composites having waste mass fractions (m) in the range of 0-20% in resin Terephthalic (E) were studied. Through mechanical and physical tests the maximum tensile and flexural strength, modulus of elasticity, maximum deformation, composite density and water absorption index were determined. A result of characterization tests confirms the viability of composite when compared to others composites using natural fibers as reinforcement or load.
