Pultrusion - Textile Scholar

 

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:

1. High volume productivity
2. Rapid processing
3. Low material scrap rate
4. Good quality control

 

Potential Problems of Pultrusion process:

• Improper fibre wet-out
• Fibre breakage
• Die jamming
• Complex Die

 

Applications of Pultrusion process:

1. Uses as Panels, Beams, Ladders
2. Tool Handles
3. Electrical Insulators
4. Light poles, Hand rails, Roll-up doors
