【摘要】 本人在生物纤维/树脂基复合材料研究学习的基础上对棕榈纤维和竹纤维分别进行了碱液预处理,然后与环氧树脂EP (Epoxy resin)复合制备了复合材料,并根据国标的要求制备了力学性能试样测试了这两种复合材料的拉伸、压缩和弯曲性能；在此基础上将以棕榈纤维/EP复合材料和竹纤维/EP复合材料为代表的生物纤维/EP复合材料与已广泛应用的人造纤维/EP复合材料(玻璃纤维/EP、碳纤维/EP)和中碳钢进行了力学性能比较分析,得出了生物纤维/EP复合材料在力学性能上代替人造纤维/EP复合材料和中碳钢的可能性；最后用复合材料生命周期评价CLCAC Composite Life Cycle Assessment)方法对以棕榈纤维/EP为代表的生物纤维/EP复合材料和以玻璃纤维/EP为代表的人造纤维/EP复合材料在整个生命周期的过程中的经济性和环保性进行了比较分析,得出了生物纤维复合材料在经济性和环保性上代替人造纤维复合材料的可行性。目前人们对生物纤维复合材料的研究仅仅停留在对其力学性能的研究上,本人首次全面的从力学性能、环境性能、经济性能上综合的对生物纤维复合材料代替人造纤维复合材料投入生产使用的可行性进行了研究。同时本人通过学习生命周期评价方法并以此为基础自创了适用于评价复合材料的CLCA,为以后研究纤维复合材料在整个生命周期中的经济性和环境性提供了新的方法。更多还原

【Abstract】 On the basis of study of biological fiber/resin matrix composites materials the author preprocessed palm-fiber and bamboo fiber respectively, which was composited by EP (Epoxy resin) and prepared composited materials and mechanical properties samples to test the traction, compression and curve performance of both composited materials by international standard. Based on this the paper compared biological fiber composited material represented by palm-fiber and bamboo fiber with widely used man-made fiber composited material(glass fiber, carbon fiber) and medium carbon steel in terms of mechanical properties, which come to the possibility that biological fiber composited materials replace man-made fiber composited materials and medium carbon steel in mechanical properties. Finally by using CLCA (Composite Life Cycle Assessment) the paper compared biological fiber composited materials represented by palm-fiber with man-made fiber represented by glass fiber in terms of environment protection and economical performance of the whole life cycle, which come to the feasibility that biological fiber composited materials replace man-made fiber composited materials in terms of environment protection and economical performance.At present research on biological fiber composited materials is limited to study of mechanical properties. The author comprehensively studied the feasibility that biological fiber composited materials replace man-made fiber composited materials in terms of mechanical, environment protection and economical performance for the first time. At the same time the author created CLCA applied to composited materials assessment based on learning Composite Life Cycle Assessment, which provides new approach to study the economical and environmental performance in the whole life cycle of fiber composited materials.更多还原
