In the present study the composites of polyethylene and hemp were prepared. In addition the polyethylene-hemp composites containing a Polybond 3039 were also obtained. The objective of this study was to evaluate the resistance of PE-hemp composites to attack by mold. At weekly intervals, composites was evaluated visually intensity of the growth of A. niger using the scale on a surface in accordance with ISO-846. It was found that A. niger grew the surface of composites within two weeks. The use of the Polybond 3039 (coupling agent) reduces the resistance of composites to A. niger. Fungus grew faster on the surface of the PE70 H30 P5 composite samples than the composite designated as PE65 H30.
