    2. Profile production processes

    2.1 Pultrusion

    It's a process resulting from the English verb "to pull", and the end of the term "extrusion", a process used in the thermoplastics industry.

    Both pultrusion and extrusion are designed to produce profiles, and use in-line equipment whose main components are the dies and the drawing bench.

    Extrusion is the pushing of a material through a die, while pultrusion is the pulling of a resin-preimpregnated fibrous support through a die using a powerful traction bench (500 to 1,000 daN).

    TDA pultrusion began in the 1960s and now accounts for 4% of the total European TDA market.

    The various studies begun in the 1980s on thermoplastic pultrusion (TP) by impregnating fibrous reinforcements...
