FRP Manufacturing - Pultrusion Photo Gallery

This describes the process used to manufacture carbon fiber laminate. The accompanying series of photographs depicts stages of the process. Carbon fiber is fed from a series of spools (Photo 1) through the spacer screen (Photo 2). Fibers then pass through a resin bath (Photo 3) and between rollers that remove excess resin (Photo 3). The fibers then pass through the laminate strip-shaper (Photo 4), and into the curing oven (Photo 4). Curing is at 750 degrees centigrade and cooling is through baths to room temperature. The cured and cooled laminate then passes through the "Puller" (Photos 5&6), between rollers (Photo 7) and finally, is rolled on the storage spool (Photo 8), or cut to length and stored in another appropriate manner. Various shapes can be manufactured as depicted by photo 9.
