Panex® 35 Pultruded Profiles Description Pultrusion is a cost-effective, continuous process for producing fiber-reinforced composite parts. Panex® 35 carbon fiber tows are fed into our proprietary impregnation and curing process that creates smooth carbon fiber laminates that provide efficient laydown when building thickness. The specific fiber alignment achieved with pultrusion delivers consistently better overall properties in laminates than any other composite manufacturing process.
