The effect of recycled powder incorporation on the mechanical properties of the thermosetting matrix (vinylester) and thermoplastic matrix (polypropylene) was studied. In the case of thermosetting matrix, flexural and tensile strength decreased with the adittion of powder.  For  filler contents highers than 50% the strength reaches a constant value.  Flexural and Young’s modulus remained constant for different powder contents.  In the case of thermoplastic matrix, strength and modulus decreased when powder reemplaced fibers.  Both, fibers and powder act as reinforcemnet because modulus increased.  Impact properties were improved with the addition of powder and fibers in comparisson with the pure matrix.
