The invention relates to the technical field of composite material wall plate structures and forming thereof, in particular to a composite material U-shaped unit stiffened wall plate and an integral forming method thereof. The composite U-shaped unit stiffened wall plate comprises a skin and U-shaped units, the multiple U-shaped units are sequentially arranged on the upper surface of the skin at intervals, and each U-shaped unit comprises a U-shaped unit web and U-shaped unit vertical ribs connected to the two sides of the U-shaped unit web correspondingly; the skin is made of multi-layer thermosetting continuous fiber prepreg, and the U-shaped units are made of multi-layer thermosetting long fiber sheet molding compound. The composite U-shaped unit stiffened wall plate and the integral forming method thereof aim at solving the problems that the mass production difficulty of composite stiffened wall plates for automobiles is large, and the efficiency is low.

    本发明涉及复合材料壁板结构及其成型技术领域,具体涉及一种复合材料U形单元加筋壁板及其整体成型方法。复合材料U形单元加筋壁板包括蒙皮和U形单元,多个U形单元依次间隔设于蒙皮的上表面,U形单元包括U形单元腹板及分别连接于U形单元腹板两侧的U形单元立筋;蒙皮的材质为多层热固性连续纤维预浸料,U形单元的材质为多层热固性长纤维片状模塑料。该复合材料U形单元加筋壁板及其整体成型方法的目的是解决汽车用复合材料加筋壁板的批量化生产难度大、效率低的问题。
