摘要
植物纤维具有绿色环保、轻质高强、吸声隔热和低碳足迹等优点,与聚合物制备成复合材料后被广泛应用于汽车、航空、建筑和包装运输等领域.本文简述了植物长纤维的种类和提取方法对其物理性能的影响,同时结合纤维取向分布、纤维表面改性、复合材料成型工艺以及拉伸载荷下复合材料的失效模式,概述了植物长纤维作为增强体时对复合材料物理性能的影响,并对植物长纤维增强可降解复合材料的应用进行了总结和展望.
Abstract
Plant fibers have the advantages of eco-friendliness,lightweight,high strength,sound and heat insulat-ing,and low carbon footprint,etc.These attributes make them highly sought-after for applications in sectors such as automotive,aerospace,construction,packaging,and transportation,particularly when plant fibers are pro-cessed into composites with polymers.This paper briefly describes the effects of the types of plant long fibers and extraction methods on their physical properties,and at the same time outlines the effects of plant long fibers on the physical properties of composites when they are used as reinforcement in combination with the fiber orientation distribution,fiber surface modification,composite molding process,and failure modes under tensile loading,as well as summarizes and looks forward to the application of plant long fiber-reinforced biodegradable composites.
