摘要:为降低连续玻璃纤维增强聚醚醚酮复合材料增材制造样件的翘曲变形,优化增材制造基础工艺参数,通过单因素试验、Plackett-Burman Design 试验与 Box-Behnken Design 试验,研究了打印过程中的热效应,即保温舱温度、层厚、成型平台温度 、打印速度等工艺参数对连续玻璃纤维增强聚醚醚酮复合材料样件翘曲变形的影响规律,得出如下结论 :研究发现打印工艺对翘曲度的影响程度是不同的,影响程度依次为 B (层厚)> C( 成型平台温度)>A(保温舱温度)。 研究发现打印工艺参数之间是会对翘曲变形产生交互作用的,并且影响程度也较为显著(PB析因试验中大于t值),即 B> C>A>AB>BC>D (打印速度)>BD。研究发现喷头温度 440 ℃,成型平台温度 100 ℃,保温舱温度 90 ℃,层厚 0.3 mm,道间距为 0.5 mm,打印速度 2 mm/s 时,翘曲度可达到 0.23%。 
Abstract:In order to reduce the warpage deformation of continuous glass fiber reinforced polyether ether ketone composite additive manufacturing samples and optimize the basic process parameters of additive manufacturing, the thermal effects during the printing process, i. e., the temperature of the holding compartment, the ply thickness, the temperature of the forming platform, the printing speed, have been studied through the one-factor test, the Plackett-Burman Design test and the Box-Behnken Design test. Other process parameters on the warpage and deformation of continuous glass fiber reinforced polyether ether ketone composite samples, and the following conclusions were drawn : It was found that the degree of influence of the printing process on the warpage was different, and the degree of influence was in the order of B (ply thickness)> C(substrate temperature)>A(temperature of the holding compartment). It was found that the printing process parameters interact with each other on the warpage deformation, and the degree of influence was also more significant (greater than t-value in the PB analytical factor test), i.e., B>C> A>AB> BC>D(printing speed)>BD. It was found that when printhead temperature was 440 ℃, forming platform temperature was 100 ℃, holding compartment temperature was 90 ℃, layer thickness was 0.3 mm, lane spacing was 0.5 mm, and printing speed was 2 mm/s, the warpage could reach 0.23%.
