摘要
Carbon fiber-reinforced composite (CFRC) has been widely used in production and life because of its superior properties such as light weight and high strength, corrosion resistance and impact resistance. However, the manufacturing of composite products is still a labor-intensive industry, mainly relying on manual labor. Since the robot arm entered the industrial production in the 1950s, it has greatly improved the production efficiency and quality, however, the current application of robot arm in the manufacturing of composite products is rare, mainly focusing on the robot arm form of automated fiber placement (AFP). The manufacturing process of composite products is tedious, and laying the composite material on the mold is an important part of the manufacturing process of composite products, which we call “lay-up”, and the use of robot arm to complete the automated lay-up operation will be a key direction for the future automation and intelligent development of the manufacturing of composite products. This paper offers a thorough examination of automated lay-up operation for robot arm, and categorizes them into two primary types: Lay-up sheets and lay-up tapes (fibers). Through case study and analysis of existing design concepts and technical methods, this paper identifies trend and suggests future development direction. The insights are of significant value for application and research related to robot arm, intelligent manufacturing of composite products, and the progression of Industry 4.0. ? 2024 Science Press.
