dc.description.abstractTHE OBJECTIVE OF THE PRESENT STUDY WAS TO OBSERVE THE MORPHOLOGY AND CHARACTERIZE THE MECHANICAL PROPERTIES OF WOOD PLASTIC COMPOSITE FOAMS. RECYCLED HIGH DENSITY POLYETHYLENE WAS MIXED WITH PINUS RADIATA D. DON (RADIATA PINE) WOOD FIBER OF 60 MESH. THE FIBER CONCENTRATIONS WERE 15 AND 25% BY WEIGHT. THE COMPOUNDS WERE FOAMED WITH A CHEMICAL AGENT ACA (AZODICABONAMIDE) AND MAPE (EPOLENE E-20) WAS USED AS A COUPLING AGENT. THE COMPOSITES WERE OBTAINED BY TWIN? SCREW EXTRUSION. THE RESULTS SHOWED THAT THE COUPLING AGENT HAD A POSITIVE EFFECT ON THE ADHESION OF THE RECYCLED POLYMER AND WOOD FIBER. THE DENSITY OF THE COMPOUNDS DECREASED WITH BLOWING AGENT AND THE MECHANICAL PROPERTIES OF HARDNESS, IMPACT, MODULUS OF ELASTICITY IN BENDING AND TENSION WERE HIGHER FOR UNFOAMED COMPOSITES. IT WAS CONCLUDED THAT INCREASING THE CONCENTRATION OF FIBER INCREASES THE MECHANICAL PROPERTIES WITH THE EXCEPTION OF IMPACT RESISTANCE OF THE COMPOUNDS THAT BY INCORPORATING THE BLOWING AGENT DECREASED SLIGHTLY.
