Abstract
The invention relates to the technical field of box type structures, in particular to a fiber reinforced composite material box type structure and a preparation method thereof.The fiber reinforced composite material box type structure structurally comprises a plurality of side plates, the side plates are connected end to end, the adjacent side plates are riveted together, and a closed frame defined by the side plates is internally provided with a plurality of first inserting plates and second inserting plates; the first inserting plates are parallel to each other, the second inserting plates are parallel to each other, the first inserting plates and the second inserting plates are perpendicular to each other and are connected together in an inserted mode, and the two ends of each first inserting plate and the two ends of each second inserting plate are riveted with the inner walls of the side plates respectively. According to the manufacturing process, the tenons and the mortises are connected in a matched mode, meanwhile, the corresponding interlocking grooves are cut in the inserting plates, and the box type structure with the high strength and the good lightweight benefit is assembled in an interlocking mode. And the problem that the fiber reinforced composite material is difficult to form in the face of a complex structure is solved through a connection mode.
