Abstract

ABSTRACT This paper presents a multi-aspect analysis of whether it is feasible and practical to process natural (plant) fibers into fabrics and mats as homogeneous or hybrid reinforcement in polymer composites for use in various industrial sectors. The current, stringent environmental rules of safe recycling and/or disposal of worn or damaged products at the end of their lifetime require new reinforcing materials to be used in polymer composites that need to meet the criteria of energy and material recycling. The paper comparatively analyzed chemical compositions of some selected (plant) natural fibers and compared their physical and chemical properties relative to commonly used synthetic (mineral and carbon) fibers. The world production of respective species of natural fibers has been presented. Industrial hemp was singled out as the possible quality reinforcement to be used in polymer composites in Poland and in Europe. The paper also provided a broader historical perspective of hemp’s importance for mankind over the past 28 thousand years. Hemp’s history and its impact on human development have been discussed. Finally, the paper compiled knowledge on industrial hemp use, agriculture, and processing as well as its current legal status in Poland and abroad.
