INTRODUCTION
• Drive shaft in car OR automobiles are generally made of steel.
• The reason for searching alternative material to steel are,
• 1. Reduce the weight of the drive shaft which reduces energy consumption.
• 2. Should be fatigue resistant and have long life.• 3. Non –corrosive, less maintenance.• 4. Allow single piece manufacturing which reduce
manufacturing cost.
LIMITATIONS OF STEEL DRIVE SHAFT
• This metallic drive shaft have limitations of weight
• Low critical speed and vibration characteristics.• When length of steel shaft is beyond 1500mm,• It is manufactured in two pieces to increase the
fundamental natural frequency which is inversely proportional to the square of the length and proportional to square root of the specific modulus.
Because of limitation of steel shaft .
One of the biggest question the automobile industry faces today is what Material to be used to reduces drastically weight of shaft which avoids energy consumption & increases it strength.
Answer is COMPOSITE MATERIAL.
LITERATURE SURVE
Durk Hyun Cho,et.al. has designed and manufactured the one piece hybrid drive shaft composed of carbon fiber-epoxy composite and an aluminum tube to reduce the weight and vibration.
A.R .Abu Talib et al, has studied and done a finte element analysis of composite drive shaft incorporating carbon and glass fibers within an epoxy matrix. He shows in his result in changing carbon fibers winding angle from 0to90 change in natural frequency
Y.A.Khalid et al, performed experiment to study bending fatigue analysis was carried out . Results obtained from his study show that increasing the number of layer of composite would enhance the fatigue strength of aluminum.
ALUMINIUM COMPOSITE DRIVE SHAFT
COMPOSITE MATERIAL
• Drive shaft is made up of,–Aluminum tube as base material and
wounded by– E-glass–Carbon fiber/epoxy composite with
different winding angle.

CONCLUSION• A composite shaft offers 1.excellent vibration damping . 2.cabin comfort 3. Reduction of wear on drive train components . 4. Increased tire traction. 5. lowered the 50% its weight. 6. use the single torque tubes which reduces assembly
time, inventory cost, maintenance, and part complexity.From this advantages
it can conclude that carbon/glass fiber-reinforced; epoxy composite drive shaft is best alternative for replacing the steel drive shaft.
