As continuous process, pultrusion offers great potential for a cost-efficient production of highly loadable profiles made of continuous fibre reinforced plastics (FRP). For a cost-efficient large-scale production, the material polyurethane (PU) is increasingly focused in current developments in addition to conventional matrix materials such as epoxy or polyester resins. Due to the low viscosity of the constituent materials, PU offers excellent impregnation properties. Thus, high performance profiles with high fibre volume contents and excellent mechanical properties can be realised. At the same time, the profile production can be realised very costefficient at high production speed due to the high reactivity of the PU. However, the use of highly reactive PU systems results in new challenges for the processing technology such as the correct construction and design of the injection box instead of a conventional impregnation bath as well as of the die technology. Furthermore, the importance of a precise process management, process control and the quality assurance increases in order to guarantee a robust and cost-efficient production.
Against this background, various applications and potentials for the pultrusion with PU in high volumes will be demonstrated in this symposium. Material suppliers, processors and customers have the opportunity to inform themselves about new material developments, suitable machine equipment and die technologies as well as methods for process control and quality assurance and discuss the presented solutions with technical experts.
