Automated Layup of High-Angle-Range Carbon Composite Parts with Static Tools - (PPT)

摘要

Composite aircraft spars are currently manufactured by hand layup or on large rotating tools of limited lengths. Computer simulation of layups of actual production parts shows that making these parts on fixed tooling requires a much larger angle range of the tow placement process on such parts when compared with layup on a rotating tool. Fixed tooling eliminates the length limitation of layup on rotating tools, permitting parts as long as the travel path of the AFP machine. Testing with a high-angle-range fiber placement machine verifies the results of the simulation. Simulation shows a wider range of parts, such as stringers, fuselage frames, and winglets, can also be produced with high-angle-range AFP machines.
