摘要
针对铁路机车用通风机叶轮产品减重和提高使用性能需求,开展了玻璃纤维增强聚合物复合材料叶轮产品研发工作,通过试验确定叶轮的铺料方法和各工艺参数,成功研发出满足铁路机车通风机使用要求的SMC材料叶轮。重点研究了SMC材料的铺料方式、模压成型压力、模压成型温度、压制速度及压制时间等对叶轮产品质量的影响。结果表明,分布铺料法比集中铺料法能得到品质更好的产品。压制工艺参数为压制温度:下模为140℃,上模为145℃;最佳压力为8 MPa;保压时间为40 min;压制速度低于20 mm/s。
This paper conducts research and development on a fan impeller products made of glass fiber reinforced polymer matrix composite by Sheet molding compound（ SMC） for weight reduction and operating performance improvement of the fan impeller products of locomotives. By testing the paving method and technological parameters of the impeller,the SMC material impeller has been successfully developed to meet the requirement of the locomotive ventilator. The research is focused on effects of charging pattern,compression molding pressure,compression molding temperature,pressing speed and pressing time of the SMC material on the quality of impeller products. Experimental results show that the distributed paving method is better than the concentrated paving method to obtain high quality products,and the pressing parameters were determined as the temperature of top and bottom mold are140 ℃ and 145 ℃,respectively,and molding pressure is 8 MPa for 40 min and pressing speed is less than 20 mm/s.
