Fatigue Property of Natural Fiber Reinforced Biomass Plastics

天然纤维增强生物质塑料是碳中性材料，有望成为玻璃钢的替代材料。研究了单向黄麻纤维增强生物质塑料的疲劳性能及其机理。PLA和PBS用作基质。结果表明，两种基体树脂在106次循环下的疲劳强度约为拉伸强度的50%，疲劳机制取决于基体树脂的延展性。

Natural fiber reinforced biomass plastics are carbon neutral materials and anticipated for alternative materials of GFRP. In this study, the fatigue property and mechanism of unidirectional jute spun yarn reinforced biomass plastics were investigated. PLA and PBS were used as matrix. As a result, it is shown that the fatigue strengths at 106cycles were about 50% of the tensile strength for both matrix resins and the fatigue mechanisms was dependent of the ductility of matrix resin.
