Pultrusion
is a process where composite parts are manufactured by pulling layers of
fibre/fabrics, bathed with resin, through a heated die, thus forming the
desired cross-sectional shape with no length limitation.
Pultrusion
Process:
Fibres are
pulled from a set of fibre creels and through a resin bath. It then pass
through a performer which gives it required cross sectional shape. The F &
C dies finalize the required shape & remove excess resin & cure the
composite so that it can be cut into required.
Advantages
of Pultrusion process:
- High volume productivity
- Rapid processing
- Low material scrap rate
- Good quality control
Potential
Problems of Pultrusion process:
- Improper fibre wet-out
- Fibre breakage
- Die jamming
- Complex Die
Applications
of Pultrusion process:
- Uses as Panels, Beams, Ladders
- Tool Handles
- Electrical Insulators
- Light poles, Hand rails, Roll-up doors
