The objective of the work was to use the wet blue leather shaving as a reinforcing material for the elaboration of a thermoplastic behavior polymer matrix composite material, which was thermally, chemically, and mechanically characterized. Six variables were measured: chip size, chip/resin ratio, percentage of water, resin temperature, pressure, and pressure time, to evaluate the tensile strength. A fractional factorial design was applied and leather sheets were made using wet blue-chip waste, Vinnapas ®400 thermoplastic resin, and distilled water. The main variable on the maximum tensile strength is given by the Chip/Resin ratio at its minimum value, followed by the chip size variable at its maximum value. The highest tensile strength value was 2,657 MPa. Young's modulus indicated that the highest value corresponds to combination #10 where 28.17 MPa were obtained. The TGA technique shows that the new material shows up to 10% presence of recycled material. The results indicate that new materials can be obtained from industrial waste products, which with proper treatment could be used for different industrial purposes.
