中文摘要:目前,自动铺丝技术是航天航空大型结构件制备工艺的发展方向,而中模高强碳纤维预浸料适用于航天航空主承力结构件的制备,达到减重的需求,因此,自动铺丝工艺用中模高强碳纤维预浸料的研究至关重要。采用HF40A中模高强碳纤维匹配EH918树脂体系,开展了预浸料的自动铺丝工艺适用性研究。通过与满足自动铺丝工艺的某预浸料对比分析,确定了满足自动铺丝工艺要求的EH918/HF40A;对比手工铺放与自动铺丝制备的板材的力学性能,数据表明,自动铺丝板材的力学性能与手工铺放板材性能相当,无明显差异;采用该材料和自动铺丝工艺制备了典型部件,并进行了无损测试,其质量满足指标要求。
英文摘要:Automated fiber placement(AFP), as the production molding process for large-scale aerospace structures, is the future direction. Intermediate modulus carbon fiber prepreg is suitable for the production of aerospace structures to meet the demand of weight reduction, so it is significant to study intermediate modulus carbon fiber prepreg for AFP. This paper uses HF40A, an intermediate modulus carbon fiber and EH918 resin system, to produce prepreg, and the applicability of its AFP process was studied. The EH918/HF40A meeting the requirements of the AFP process was determined by comparison with a prepreg that satisfies the process. After comparing AFP with the mechanical properties of laminates using the hand lay-up process, it can be found that their mechanical properties are equivalent. Additionally, Typical parts were prepared with the material through AFP process, and non-destructive testing was performed which proved that the quality met the requirements of the index.
