Pultrusion is a continuous process for manufacturing composites with a uniform cross-sectional shape. A 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 the die length. Pultrusion yeilds continuous lengths of material with high unidirectional strengths. PPG fiber glass products used for pultrusion include HYBON single-end and multi-end fiber glass rovings as well as MatVantage® II continuous-strand fiber glass mat.
