Plastic forming process where fiber and polymer solution are processed in layers on a mold. Beskrivning The process An open mold [1] is prepared by adding a anti-adhesive layer to make the finished part easier to remove. The form is then rolled [2] or brushed with a self-curing polymer solution and coated with fiber sheets, usually fiberglass [3]. Rolling and fiber addition is repeated layer by layer until the desired thickness is achieved. The build up is usually cured at room temperature and is then removed from the mold.

Advantages and disadvantages In comparison with alternative methods Widely used method Low tool cost Long fibers Large variety of materials High fiber content Perfect for prototypes Surface finish (not the form) depending on the skill of the operator Hard to gauge the mechanical properties
