German machinery maker KraussMaffei reports that it has created a second pultrusion line at its reaction process machinery technology center in Munich.The new system is designed to produce composite reinforcement for concrete structures and to produce flat panels The combination of the pultruded system iPul with the first structure of the structure creates an excellent research environment for KraussMaffei's development and testing of pultrusion processes.
Sebastian Schmidhuber, head of the KraussMaffei reaction process machinery division, explained why the company entered pultrusion technology a year ago: "The pultrusion process is a simple technique for producing low-cost profiles, and few are currently available Turnkey project, a technology that is still in its infancy, and KraussMaffei is exceptionally knowledgeable and knowledgeable about fiber, metrology and related processes. '
The latest development result is the iPul system developed in 2017. Compared with the traditional drawing process, the system significantly increases the production rate and significantly broadens the application fields of pultrusion processes. "Schmidhuber said:" The new production line is capable of producing plates The combination of profile iPul systems gives us a comprehensive and unparalleled opportunity for research and development in pultrusion technology for our global customers. '
KraussMaffei said that the use of pultruded glass fiber or carbon fiber reinforced epoxy composite material reinforcement for the construction industry to provide a more broad space for development.Schmidhuber said: "Composites pultruded profiles compared with the traditional more Corrosion resistance and therefore the covering of concrete layers can be very thin. "Other advantages include light weight, low shipping costs, ease of operation at the construction site, and the ability to roll on rolls that are endless at the end of a pultrusion line Etc. Functional buildings in infrastructure and in corrosive environments are typical applications for composite pultruded profiles.
According to KraussMaffei, until now, there has been no success in finding an effective way to serialize production.Schmidhuber also said: "The production rate of composite stiffeners using conventional drawing methods still depends on relatively low stretch The rate, in some cases only 0.5 m / min. With the new iPul system, our pultrusion rate can be up to 7 times its rate of production, thus producing a product that can be a low-cost alternative to traditional rebars. Smalfi works closely with a number of companies, including Evonik, which supplies resin for the project, Thomas Technology, which specializes in radial pultrusion, and Alpex, which specializes in stamping technology.
The iPul project partners include Covestro, which manufactures polyurethane-based window frames, which has been approaching proven technology in terms of production efficiency thanks to the iPul system and its higher production rates New Market Gate Huntsman is another partner in the project, both of which are involved in research and development of pultruded composite reinforcements for large wind turbine blades.
