  1. AUTOMATION OF FIBER COMPOSITE MANUFACTURING PROCESS (In the partial fulfillment for the course of Mechatronics, ME5643) (Group 8) Duc Anh Sang Yoon Lee Chandresh Dubey Prof. V. Kapila Polytechnic University

  2. Overview • Introduction • Objective • Mechanical Design and Layout • Electrical/Electronic Design • PBASIC Code • Cost Estimation • Limitations • Future developments • Conclusion • Acknowledgement

  3. Introduction

  4. Objective • Device a prototype model demonstrating automation of fiber composite material manufacturing process. • Prototype should be capable of cutting pieces up to length of 6 inches. • Up to 30 mm composite stack should be handled.

  5. Mechanical Design and Layout

  6. Mechanical Design(Drive Rollers and Cutter)

  7. Mechanical Design(Fiber Transportation)

  8. Mechanical Design(Fabric Holding and Resin Application)

  9. Electrical/Electronic Design Key Hardware • Stepper motors • Servomotors (continuous and standard) • Linear Actuator • Pressure sensor • Stepper motor drive IC (ULN2803) • Mosfets • 12V power supply etc.

  10. Circuit Diagram(Stepper Motor – Main roller and transport drive)

  11. Circuit Diagram(Servo Motors – Pull roller, transport and holding platform)

  12. Circuit Diagram(Linear Actuator - Cutter)

  13. PBASIC Code - 1

  14. PBASIC Code - 2

  15. PBASIC Code - 3

  16. PBASIC Code - 4

  17. Limitations • The model proposed in its current state doesn’t provide any means to check the fiber orientation which drastically affects composite material property • Resin application is to be done manually • The holding mechanism proposed is slow due to use of threads but can be easily changed to other linear actuators

  18. Future Developments • Incorporate a sensory system to check fiber orientation as it directly affects the composite strength and sorting out incorrect pieces • Device the mechanism which would allow differently oriented fibers to be processed serially so that mixed type composites can be produced

  19. Conclusion • The mechanism operates slowly but satisfactorily. • It was found that individually the components performed as required but in integrated form synchronization difficulties exist • The methodology can be easily adopted is simple and adaptive for manufacturing
