Manufacturing Process -- Pultrusion

Pultrusion is a continuous process for manufacturing composites with a uniform cross-sectional shape. Fiber reinforcement is pulled through a resin-impregnation bath and into a shaping die where the resin is subsequently cured, or set. Heating to both gel and cure the resin is accomplished within die length. Pultrusion yields continuous lengths of material with high unidirectional strength.


Raw Material

Material: 65% fiberglass & 35% resin or 75% carbon fiber & 25% resin

Fiberglass: S-glass, E-glass, etc. The most common material is E glass fiber, low alkali metal oxide content of the glass fiber. The specific content of alkali metal oxide, domestic current provisions are not more than 0.5%, foreign generally about 1%

Carbon fiber: Domestic carbon fiber, imported carbon fiber such as Tairyfil carbon fiber and Toray carbon fiber

Resin: Polyester Resin, Vinyl Ester Resin, Polyurethane Resin and Epoxy Resin, etc.
