Description:	The use of biodegradable materiais from renewable resources has gained more attention in recent years. The advantages of natural fiber composítes are lheir low density, low cost, renewable characteristics and complete biodegradability. ln this study, unrlpe coconut fibers were used as reinforcement in a biodegradable polymer matrix of starch/EVOH. The effect of fiber treatments (washing with water and mercerization) on lhe properties of lhe biocomposites was evaluatad by tensile and thermal properties. This study revealed that lhe treatments produced modifications on the surface and in-.,roved lhe thermal stability of lhe fibers and consequently of lhe composites. The best results were obtained when fibers were mercerized. ln this case, tensile strength~ increased by about 52.8% compared to C00'1)0Sítes made with untreated fibers, and 33.3% compared to composites without fiber, indicating lhat the conditions of mercerization used promoted better fiber-matri adhesion, allowing an efficient stress transfer from the matrix to lhe fibers.
