Modeling and Optimization of Process Parameters for Laser Transmission Connection of PA66GF30 and GFREP
摘要: 针对热固性聚合物与热塑性聚合物的连接需求，采用纳秒脉冲激光连接系统对热固性玻纤增强环氧树脂与热塑性纤维增强尼龙进行激光透射连接。为了提高连接强度，利用激光对热固性聚合物进行表面织构预处理，然后再进行两者激光连接。基于响应曲面法对两者的激光透射连接建立激光功率、连接速度、表面织构预处理各工艺参数与连接强度及预处理时间的数学模型，分析各工艺参数的交互式影响，并通过粒子群算法求解得出最优参数组合。结果表明对连接强度的交互式影响较为显著的是孔间距–扫描次数、连接速度–孔间距、激光功率–连接速度。试验所建模型在设定工艺参数内的任一点的预测结果与实验结果具有较高的一致性。
Abstract: According to the connection requirements of thermosetting polymers and thermoplastic polymers, a nanosecond pulsed laser connection system is used for laser transmission connection of thermo-setting glass fiber reinforced epoxy resin and thermoplastic fiber reinforced nylon. In order to im-prove the connection strength, the surface texture pretreatment of the thermosetting polymer is carried out by laser, and then the two kinds of material are connected with laser. Based on the re-sponse surface methodology, a mathematical model of laser power, connection speed, surface tex-ture pretreatment, various process parameters, connection strength and pretreatment time was established for the laser transmission connection of the two, and the interactive influence of each process parameter was analyzed. The algorithm solves the optimal parameter combination. The results show that the most significant interactive effects on connection strength are hole spac-ing-scan times, connection speed-hole spacing, laser power-connection speed. The prediction results of the model built in the experiment at any point within the set process parameters are in high con-sistency with the experimental results.
