The invention relates to the technical field of aircraft part manufacturing, and discloses a hyperbolic cap type stringer prefabrication forming method and a hyperbolic cap type stringer. The hyperbolic cap type stringer prefabrication forming method comprises the steps that 100, a three-dimensional model of a hyperbolic cap type stringer is unfolded into a simulation plane material piece in a preset unfolding mode; step 200, cutting each layer of material sheet according to the shape of the simulated plane material sheet, and sequentially paving each layer of material sheet to form a flat plate blank; and 300, the flat plate blank is installed in a hot mold pressing mold in a preset positioning mode, and hot mold pressing is conducted. According to the hyperbolic cap type stringer formed through the prefabrication forming method for the hyperbolic cap type stringer, the accuracy of the extending direction of fibers in all layers of material pieces is good, the symmetry is good, it is guaranteed that the performance of a workpiece meets the requirement, the forming efficiency of hot mold pressing is high, and the forming efficiency of the hyperbolic cap type stringer is guaranteed.

    本发明涉及飞机零部件制造技术领域,公开了一种双曲帽型长桁预制成型方法及双曲帽型长桁。所述双曲帽型长桁预制成型方法包括:步骤100,以预设展开方式将双曲帽型长桁的三维模型展开为模拟平面料片;步骤200,参照所述模拟平面料片的形状裁切各层料片,并依次铺贴各层料片,以形成平板坯料;步骤300,将所述平板坯料以预设定位方式安装在热模压模具中,并进行热模压。发明的双曲帽型长桁预制成型方法成型的双曲帽型长桁,各层料片中纤维的延伸方向的准确性好、对称性好,保证工件的性能符合要求,且热模压的成型效率高,保证了双曲帽型长桁的成型效率。
