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.
摘要
本文从多个方面分析了将天然（植物）纤维加工成织物和垫子，作为各种工业部门使用的聚合物复合材料中的均匀或混合增强材料是否可行和实用. 目前，对磨损或损坏产品在使用寿命结束时进行安全回收和/或处置的严格环境规则要求在聚合物复合材料中使用新的增强材料，这些材料需要满足能源和材料回收标准. 本文比较分析了一些精选的（植物）天然纤维的化学成分，并将其与常用的合成（矿物和碳）纤维的物理和化学性能进行了比较. 介绍了世界上各种天然纤维的生产情况. 工业大麻被选为波兰和欧洲聚合物复合材料中可能使用的优质增强材料. 该论文还对大麻在过去28000年中对人类的重要性提供了更广泛的历史视角. 讨论了大麻的历史及其对人类发展的影响. 最后，本文汇编了有关工业大麻使用、农业和加工的知识，以及其在波兰和国外的法律现状.
