Filament winding is a fabrication technique for forming reinforced plastic parts of high strength and light weight.
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.
1. circular type 2. rectangular type
Curing-Polymerization of composites on mandrel.
Pressure chambers-System also requires pressure in addition to
heat.
Fabrication variables Processing variables Winding variables Material's variables Environmental variables weathering humidity
Advantages –1. a very fast and economic method 2. Structural properties of laminates can be
very goodLimitation –1. Lack of ductility2. Low modulus of elasticity
