The high-efficiency and low-cost automated manufacturing technology of composite materials is core in the international composite material field. As a scientific and technological multinational innovation enterprise, ATCC has a series of the most advanced automatic laying equipment worldwide. Through digital and automated means, the automatic laying and continuous automatic cutting of composite materials can be realized accurately and efficiently. The large-size paving area of 8.5m*1.6m is suitable for continuous production of composite material preforms of various sizes, thicknesses, and shapes. It has been maturely applied to fuselage frames, beams, ribs, boxes, automobile structures, and other components.
The hot diaphragm forming technology is based on equipment and continuous forming production processes independently developed by ATCC China and Germany. It is expected to form structural parts with a variety of shapes and thicknesses within 8 meters. The prepreg layer, which is automatically laid and cut, can be quickly and efficiently formed one or more times to achieve complex product shape requirements, and can ensure that the fiber sliding is controllable during the production process without wrinkles, waves, delamination, and inclusions, in order to obtain efficient and stable product preforms.
The ATCC Sino-German R&D Engineering Center team has made bold innovations in structural design. The carbon fiber drive shaft and metal flange adopt spline connection and integrated solidification methods to realize the smooth transmission of the torsion, tension, and compression load of the shaft system. It solves the technical difficulties of the connection between the carbon fiber drive shaft and metal flange, and improves the torsion and bending performance of the drive shaft. Additionally, this technology ensures that the carbon fiber transmission shaft will not be damaged or peeled off during long-term use, and product application and mass production are realized.
The composite fuel tank has the characteristics of being corrosion resistant, age resistant, and light weight. Compared with an aluminum fuel tank, the weight can be reduced by 20% based on meeting the performance requirements of the fuel tank. The ATCC team made bold innovations in structural design and adopted an integrated design method for the fuel tank, which greatly reduced the number of parts and connections (such as bolts, etc.). This method also greatly reduces the assembly process, the overall quality of the fuel tank is higher, and the sealing performance is better.
Compared with the traditional wing, the composite wing can not only reduce weight and solve the problems of fatigue, but also bring great benefits to aerodynamics. The ATCC team actively explored and adopted all-composite wing bonding technology, which greatly reduces tooling, parts, and fasteners, and can evenly distribute the wing stress. This technology improves the quality of wing products while reducing production costs and shortening the production cycle.
