Economic and Manufacturing Considerations for Composite Driveshafts 800005

A brief review of various composite driveshaft concepts is given. Included are the carbon-glass hybrid filament wound, carbon fiber overwrapped aluminum, pultruded, and fabric wrapped versions. The basic fabrication methods are explained with advantages and disadvantages of each.
The results of a detailed economic study of the various fabrication methods are given. Included variables are material costs (carbon fiber, prepreg, and resin), and production rates. A second concurrent study compared the various fabrication methods based on more qualitative factors such as experience, reliability, design simplicity, etc. The results of both studies conclude that a filament wound all-composite structure is the most attractive.
Finally, the filament winding manufacturing concept is described. The current Mark VI machine concept, together with overall manufacturing scheme, is described.
