The most complex J-type stiffener in the composite reinforced panel is manufactured by using automated bending technology

the core material is manufactured by using automated pultrusion molding technology

and then using the co-bonding method to manufacture the composite material that meets the requirements of reinforced panel. The automated molding technology of composite stiffener and core material has been successfully applied to the manufacture of composite reinforced siding parts

which improves production efficiency and stabilizes product quality. It lays a foundation for the establishment of automated production line of composite stiffened panel.
