Abstract

During laser assisted processing of thermoplastic composites, the individual effects of laser power, tape speed and consolidation pressure on the interply bond strength cannot be easily separated unless a large number of experiments is carried out. Because the properties of an end product depend upon the selection of processing conditions, it is essential that the conditions under which a well consolidated part is obtained should be defined. To investigate the effects of individual process parameters from a minimum number of tests, the Taguchi method is applied. For this investigation, PEEK/carbon fibre (APC-2) thermoplastic composite rings were manufactured by a thermoplastic tape winding process at selected conditions, and the influence of dominant process parameters on interply bond strength was evaluated. The influence of three dominant factors, namely laser power, consolidation pressure and tape speed, on bond strength were investigated. The experimental design involved using L₉ orthogonal arrays, and the percentage contribution of each factor to the quality of bonding was estimated by the ANOVA technique.

田口法在在线加固工艺强化中的应用

在热塑性复合材料的激光辅助加工过程中，除非进行大量的实验，否则很难将激光功率、胶带速度和固结压力对间键强度的单独影响分离出来。由于最终产品的性能取决于加工条件的选择，因此必须确定获得良好固结零件的条件。为了研究单个工艺参数对最小试验次数的影响，采用了田口法。在选定的条件下，采用热塑性胶带缠绕工艺制备了PEEK/碳纤维(APC-2)热塑性复合环，并评估了主要工艺参数对其间键合强度的影响。研究了激光功率、固结压力和胶带速度三个主要因素对胶结强度的影响。实验设计采用L9正交阵列，并通过方差分析技术估计每个因素对键合质量的贡献百分比。
