Description
Technical Field
The invention relates to a bending and twisting resistant composite forming method for a polygonal composite material cylinder with long inner ribs and a bending and twisting resistant composite forming production line for the polygonal composite material cylinder with the long inner ribs based on the composite forming method. The long inner rib means that the cylinder body is provided with a longer protruding rib shape on the inner side of the cross section, and the dimension of the rib is in the same order of magnitude as the dimension of the cross section of the cylinder body; the polygon refers to geometrical shapes such as quadrangle, pentagon, hexagon, octagon and the like; the composite material is a composite material formed by compounding carbon fibers/glass fibers or the like as reinforcing fibers and a resin or the like as a matrix.
