The influence of atmospheric factors on ageing of polymer composites reinforced with lignocellulose fibers has been analysed. Three natural fibers obtained from the husks of cultivated plants: rice, oat, millet husk were used as fillers. The microscopic analysis of the surfaces revealed melting of the top layer of the polymer matrix, leading to the exposure of the filler particles. The carried out mechanical tests showed the best properties for profiles with oat hulls in the initial state and after ageing, whose properties were comparable to those of commercial profiles reinforced with rice hulls.
