The invention relates to a large segmented composite material shell connection structure. A left-segment rocket engine shell and a right-segment rocket engine shell of the large segmented composite material shell connection structure are fixedly connected through a left connection piece and a right connection piece, spiral winding is performed between each first fiber winding hanging pile and a left-segment engine shell sealing head through fiber to form a first spiral inclined winding layer, annular winding is performed on the outer surface of the first spiral inclined winding layer through fiber to form a first annular winding layer, spiral winding is performed between each second fiber winding hanging pile and a right-segment engine shell sealing head through fiber to form a second spiral inclined winding layer, and annular winding is performed on the outer surface of the second spiral inclined winding layer through fiber to form a second annular winding layer. By means of the large segmented composite mat
