The invention relates to a cross-shaped connecting structure between a composite bulkhead and a deck for a ship. The connecting structure is composed of a fiber reinforced connecting part, a lower corner reinforcing core material, a fiber reinforced arc reinforcing panel, an upper corner reinforcing core material and a fiber reinforced right-angle panel; wherein the fiber reinforced connecting part is formed by paving a positioning section T-shaped fiber reinforced material and a reinforcing section L-shaped fiber reinforced material; the lower corner reinforcing core material is composed of ahard triangular core material, and the lower arc reinforcing panel is formed by paving a fiber reinforcing material; the upper corner reinforcing core material is composed of a hard triangular core material, and the upper right-angle panel is formed by paving a fiber reinforcing material. The whole cross-shaped connecting structure is tightly connected with the composite material ship body bulkhead and the composite material deck structure in the mode of combining bolt mechanical connection and resin mucilage glue. The connecting structure is good in connecting strength, structural stress concentration can be effectively reduced, and water tightness is guaranteed.

    本发明是一种舰用复合材料舱壁和甲板间十字型连接结构,该连接结构由纤维增强连接部件、下部角隅加强芯材及纤维增强圆弧加强面板、上部角隅加强芯材及纤维增强加强直角面板组成。其中,纤维增强连接部件由定位段T型、加强段L型纤维增强材料铺贴组成;下部角隅加强芯材由硬质三角形芯材组成,下部圆弧加强面板由纤维增强材料铺贴组成;上部角隅加强芯材由硬质三角形芯材组成,上部直角面板由纤维增强材料铺贴组成。整体十字型连接结构通过螺栓机械连接和树脂粘胶相结合的方式和复合材料船体舱壁、复合材料甲板结构紧密连接。该连接结构连接强度好,能有效减少结构应力集中并保证水密。
