Research On Manufacturing Process Of Reinforce Carbon Fiber Composite Laminate With I-stiffeners

"Materials and parts " synchronous forming——the characteristics of Composite, become the integral and the structure of the big advanced commercial and one of the main structure material and material, dosage is growing. Along with the progress of the equipment and technology, the composite material molding automation and low production cost has become a inevitable development trend. At present, in terms of composite materials, and manufacturing equipment, technology blockade and restrictions, especially high-end composite materials and products for imported products, such as to promote the domestic application technology in the high-end composite material manufacturing industry, through manufacturing technology research, master the domestic civil aircraft in composite manufacturing processes.This article first analyzes the status of composite application technology and manufacturing technology at home and abroad, especially for Boeing and airbus aircraft wing were analyzed, and the understanding of composite stiffened panel design characteristics, the characteristics of manufacturing process technology, this article take the key point, technology and direction.Factory type composite stiffened panel design structure and the difficulty in the study of comprehensive analysis, technological process and manufacturing process for the new design, through the experiment and optimized, a composite material is suitable for the work of the aircraft of reinforced wall technology and manufacturing solutions.Equipment, as the company’s existing automatic laying belt blanking and form a complete set of equipment, technology, etc, according to the test plan, with the structure characteristics of a type stringer and skin, dry skin- wet stringer adhesive to curing and dry stringer- wet skin glue covered a total of two process such as curing, optimizing the plan and determine the best processing technology parameter of the panels.To in material performance and the performance of the wall plate, the results are analyzed and discussed, highlights in the manufacture of composite material laminated parts need to be pay attention to the performance parameters of presoak material, laminate mechanical performance parameters, with long truss manufacturing of defect correction method, etc., for subsequent reinforced wall slab manufacturing solutions.This type of worker process scheme and parameter design, the wall board of the work to choose the long boom- wet skin glue covered a total of curing process can effectively solve the work type composite material made of reinforced wall technical problems, through special process control for forming quality is stable with reinforced composite wall panel test pieces. At the same time discusses the forming and existing some problems in, some of the conclusions, the data, for the subsequent aircraft manufacturing large-scale composite wing shape provides manufacturing technology method.
