摘　　要：以聚乳酸(PLA)为基体,玄武岩纤维(BF)为增强体,采用熔融沉积(FDM) 3D技术来制备玄武岩纤维增强PLA(BF/PLA)复合材料试样,并研究了层高、打印速度和打印温度对复合材料力学性能的影响。结果表明:随着打印层高的增加,BF/PLA复合材料的纤维体积分数减小,拉伸强度和弯曲强度显著降低;随着打印速度增加,玄武岩纤维与PLA的包覆效果变差,试样拉伸强度和弯曲强度降低;随着打印温度增加,试样拉伸强度和弯曲强度略有增加。The polylactic acid(PLA)is used as the matrix and basalt fiber(BF)is used as the reinforcement.Fused deposition modeling(FDM)3D technology is used to prepare basalt fiber-reinforced PLA(BF/PLA)composite samples.The effects of printing layer height,printing speed and printing temperature on the mechanical properties of composite materials are studied.The results show that as the printing layer height increases,the fiber volume content of BF/PLA composites decreases,and the tensile strength and bending strength decrease significantly;as the printing speed increases,the coating effect of basalt fiber and PLA becomes worse.The sample tensile strength and bending strength decrease slightly as the printing temperature increases.
