  1. FILAMENT WINDING BY- RAJESH KUMAR DWIVEDI 2008AMD3100

  2. INTRODUCTION Filament winding is a fabrication technique for forming reinforced plastic parts of high strength and light weight.

  3. Why we use filament winding The use of circumferential wrapping to increase the bursting strength.

  4. Manufacturing • Precision high-speed positioning of continuous fiber in a pre-determined pattern is the basis of the filament winding process . • In this there is a mandrel that the fiber and resin wound upon, is cured in room temp or in oven. After cure mandrel is removed leaving a hallow composite structure. • circular type • rectangular type

  5. Methods of winding • Circumferential winding • Helical winding

  6. Curing- Polymerization of composites on mandrel. Pressure chambers- System also requires pressure in addition to heat.

  7. Material • Epoxy resins • Polyester resins • Phenolic resins • Silicone resins

  8. Factors affecting properties • Fabrication variables • Processing variables • Winding variables • Material's variables • Environmental variables weathering humidity

  9. Advantages – • a very fast and economic method • Structural properties of laminates can be very good Limitation – • Lack of ductility • Low modulus of elasticity

  10. Application • Storage tank • Railway tank car • Pipe • Aerospace
