摘要
为提升复合材料加筋壁板的制造精度,本文基于复合材料共胶接成型工艺,研究了复合材料加筋壁板筋条的结构组成,分析得出了制备筋条R区填角料所需预浸料用量的计算模型,实现了共胶接复合材料加筋壁板筋条R区的精确填充;优化了共胶接复合材料加筋壁板的成型工装结构设计方案,改善了工装定位销的定位精度,实现了筋条轴线位置的精确控制;制作了筋条外形轮廓的辅助切割检查样板,实现了筋条轮廓边距的准确切割。通过筋条R区的精确填充、筋条轴线位置的精确控制及筋条轴线边距的准确切割实现了共胶接复合材料加筋壁板的精确制造。
To improve the manufacturing accuracy of composite stiffened panels,this paper study the structural composition of composite stiffened panels based on the co-bonded forming process of composite stiffened panels.A calculation model is derived for the amount of prepreg required to fill the R region of the stiffeners,achieving precise filling of the R zone of co-bonded composite stiffened panels.The structural design of the molding fixture for composite stiffened panels is optimized,improving the positioning accuracy of the positioning pins and achieving precise control of the stiffener axis line position.A cutting template is made for the outline of the stiffener to achieve accurate cutting of the stiffener edge distance.By precisely filling the R zone of the stiffeners,precisely controlling the stiffener axis line position,and accurately cutting the stiffener edge distance,the precise manufacturing of composite stiffened panels with stiffeners is achieved.
