Pultrusion involves pulling a collection of fibres in the form of roving, tow , mat or fabric through a resin bath and then through a heated die to cure the resin. This produces a continuous prismatic section which is similar to the pultrusion die. The process is used with a variety of resin and fibre types to produce products ranging from simple round bar to complex architectural mouldings. A flying cut-off saw is programmed to cut the product to the desired length. Since the predominant fibre direction is usually longitudinal this is reflected in the properties of the products which are usually strong and stiff in tension and bending with poor transverse properties. This limitation can be overcome by incorporating mats and fabrics with transverse reinforcement to provide a balance of properties.
The key elements of the manufacturing process are:
Reinforcement Handling
This consists of roving creels, mat and veil dispensers, and winders or braiders where other than axial reinforcement is required.
Resin Impregnation
This can consist of a simple resin bath or pressure/vacuum impregnation device
Preforming Dies
These serve to guide the impregnated reinforcement into the correct position, remove excess resin, provide pre-compaction to the approximate profile in order to assist air removal, wetting and to reduce the pressure in the main die.
