การหาเส้นทางการพันเส้นใยบนท่อโค้งคอมโพสิตสำหรับเครื่องพันเส้นใยอัตโนมัติ

Abstract

Composite pipes have an important role in the construction industry because their advantages in terms of strength, corrosion resistance, lightweight and non-rust. In manufacturing of composite pipes, glass fibers are dipped into resin solution and winded on a mandrel pipe. This research determines the elbow pipe filament winding path on an elbow mandrel by using helix curve equations. A CAD/CAM software determines number of winding rounds to obtain the desired filament angle, and simulates the filament winding pattern. After that, the filament path is transformed to the winding machine path. The experiments show that the filament winding machine is able to automatically wind the filament close to the design pattern. The validation is done by comparing the machine winding path with the simulation winding path on an elbow pipe. The result shows that the machine works according to the design. This study provides knowledge on determination of the filament winding path on elbow pipes for the automatic winding machine, and can also be applied on various elbow pipe sizes.
