Composite material profile variable stiffness connecting joint and connecting method
The invention discloses a composite material section variable-rigidity connecting node and a connecting method, and the composite material section variable-rigidity connecting node comprises a fiber reinforced composite material rod piece, a metal lining connected with one end of the fiber reinforced composite material rod piece in an inserting manner, and a splice plate and a locking assembly which are distributed on the two sides of the fiber reinforced composite material rod piece, the fiber reinforced composite material rod piece and the metal lining are both hollow pipe pieces with square cross sections, the metal lining and the fiber reinforced composite material rod piece are connected in a thickness gradual change mode, and a first connecting inclined face is arranged on the inner wall of one end of the fiber reinforced composite material rod piece. The outer wall of the metal lining is provided with a second connecting inclined face matched with the first connecting inclined face, an adhesive layer is arranged between the first connecting inclined face and the second connecting inclined face in a bonding mode, and the metal lining, the fiber reinforced composite material rod piece and the splice plate are provided with through holes used for installing a locking assembly. The connecting structure has the advantages of being high in connecting joint strength, good in breaking ductility and uniform in bolt load distribution.
