The invention belongs to the technical field of aircraft manufacturing, and discloses a preparation method of an aircraft bulkhead and the aircraft bulkhead. The preparation method of the aircraft bulkhead comprises the following steps: S1, drawing a bulkhead reinforcement model according to the flattened aircraft bulkhead; s2, selecting a plurality of punctuations distributed at intervals in the breadth direction of the bulkhead reinforcement model from any section of the bulkhead reinforcement model, and determining the arc length L of the bulkhead reinforcement model corresponding to each punctuation; s3, determining a corresponding radius value R according to the arc length L corresponding to each punctuation; s4, designing and manufacturing a curling roller suitable for weaving requirements of a weaving machine according to the radius value R corresponding to each punctuation point; s5, applying the curling roller to a weaving machine and weaving a bulkhead reinforcement body; and S6, the bulkhead reinforcement body is placed into the forming mold, the matrix material is injected into the bulkhead reinforcement body, and the aircraft bulkhead is manufactured. The inner side area of the aircraft bulkhead is not prone to wrinkling.
本发明属于飞机制造技术领域,公开了一种飞机隔框的制备方法及飞机隔框。飞机隔框的制备方法包括如下步骤:S1,依据展平后的飞机隔框绘制隔框增强体模型;S2,在隔框增强体模型的任意一个截面选取多个沿隔框增强体模型的幅宽方向间隔分布的标点,并确定每个标点对应的隔框增强体模型的弧长L;S3,根据每个标点对应的弧长L确定对应的半径值R;S4,通过每个标点对应的半径值R设计并制造适用织机织造要求的卷曲辊;S5,将卷曲辊应用在织机上并织造出隔框增强体;S6,将隔框增强体置入成型模具,并将基质材料注入隔框增强体,以制得飞机隔框。本发明使得飞机隔框内侧区域不易发生褶皱。
