Filament winding is a fabrication technique for
forming reinforced plastic parts of high
strength and light weight.
The use of circumferential

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.

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