| 摘 要： | 以聚乳酸纤维为基本相,亚麻纤维为增强体,通过层结构铺装热压制得亚麻纤维/聚乳酸复合材料。通过单因素试验分析了各因素对复合材料力学性能的影响,确定了各因素试验范围。利用响应面法确定出最优的工艺参数:亚麻用量43%,硅烷用量4%,热压温度190℃。按照此工艺条件制造的复合材料的拉伸强度、拉伸模量、弯曲强度和弯曲模量分别为49.70 MPa、3.12 GPa、33.50 MPa和2.34 GPa。

| Abstract: | Film stacking and hot pressing techniques were applied to produce flax fibers(FF)/polylactic acid(PLA) compo-sites using PLA film as basic phase and FF as reinforcement.The relationships between the main process parameters and the performances of the composites were analyzed by single-factor experiments in order to determine the range of the experimental factors.The optimal parameters were determined by the response surface methodology as flax addition 42%,silane addition 4%,and hot-pressing temperature 190 degrees C.The tensile strength,tensile modulus,flexural strength,and flexural modulus of the composites under the optimal process conditions were 49.70 MPa,3.12 GPa,33.50 MPa,and 2.34 GPa,respectively. |
