Abstract
Filament Winding Process is a comparatively simple operation in which continuous reinforcements in the form of roving are wound over a rotating mandrel. And now well established as a versatile method for storage tanks and pipe for the chemical and other industries.


This paper investigates that technology is ensured by filament winding process and composites shaft of small ship is developed. Property of composites shaft has high strength and effect of materials reduction as it is compared to metal shaft. So, purpose of the study is to ensure manufacture process of composites shaft, stress analysis and design of structure for small ship


The purpose of this study is to design and to analyze the stress of composite shaft which is wound by filament winding method. The composites shaft has high strength and reduction in weight compared to metal shaft. Manufacturing composites shaft is used to metal shaft(SUS420), it is diameter(D=40), length(L=300). The shaft is designed to considerate tensile, compression, torsion and vibration.


As composites shaft which is influenced the largest by torsion was analyzed, the diameter is as large as shear stress is smaller. If angle of winding is 90-degree, shear elongation becomes large and torsion moment is large. In order to replace metal shaft with composite shaft, the diameter of shaft was determined on 40mm and the ratio of diameter was determined on 0.4 for torsion moment. As angle of winding is 30-60 degree, shear elongation was not different. In the case that angle of winding is 75-degree over, composites shaft may be fractured by torsion. So, diameter of composite shaft must be grown, because of safe of composite shaft.
