Date: 9 October 2018

As continuous process, the pultrusion offers great potential for a cost-efficient production of highly loadable profiles made of continuous fibre reinforced plastics. For a large-scale production, highly reactive resin materials are increasingly focused in current developments (e. g. polyurethanes, epoxy resins or insitu polymerizing thermoplastics). Due to the low viscosity of the constituent materials, they offer 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 cost-efficient at high production speed due to the high reactivity of the material systems.

However, the use of highly reactive 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 quality assurance increases in order to guarantee a robust and cost-efficient production.

Against this background, various applications and potentials for the pultrusion with reactive materials in high volumes will be demonstrated and discussed in this symposium. Researchers, material suppliers, processors and customers have the opportunity to inform themselves about new material developments, suitable machine equipment and die technologies as well as current research activities and discuss the presented solutions with technical experts.
