Resumen
This study aimed to evaluate physical and mechanical properties of wood-plastic composites using materials of low processing level. Residues from carpentry as wood shavings from three forest species (Pinus elliottii, Hovenia dulcis and Maclura tinctoria), and thermoplastic type were used. Data were submitted to Duncan’s test with 95% confidence. In relation to the modulus of rupture (MOR) and elasticity- (MOE), all treatments presented successful results, without difference. For the tests of internal bond and screw pullout, the results were not satisfactory. For this last test, the best result was for Hovenia dulcis. In relation to swelling in 2 h and 24 h, all treatments presented positive results. In general, the results were not influenced by the species used.
