INTRODUCTION Filament winding is a fabrication technique for forming reinforced plastic parts of high strength and light weight.
Why we use filament winding The use of circumferential wrapping to increase the bursting strength.
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
Methods of winding • Circumferential winding • Helical winding
Curing- Polymerization of composites on mandrel. Pressure chambers- System also requires pressure in addition to heat.
Material • Epoxy resins • Polyester resins • Phenolic resins • Silicone resins
Factors affecting properties • Fabrication variables • Processing variables • Winding variables • Material's variables • Environmental variables weathering humidity
Advantages – • a very fast and economic method • Structural properties of laminates can be very good Limitation – • Lack of ductility • Low modulus of elasticity
Application • Storage tank • Railway tank car • Pipe • Aerospace
