Die Verwendung der reaktiven, niederviskosen Monomerschmelze ermöglicht die schnelle Infiltration von Faserhalbzeugen, ist jedoch sehr empfindlich gegenüber äußeren Einflüssen. Einer der größten Einflussfaktoren ist Wasser, das in Form von Luftfeuchtigkeit in Kontakt mit den zu verarbeitenden Materialien kommt. Die während der Verarbeitung eingebrachten Wassermoleküle reduzieren die Reaktivität der Monomerschmelze.The production of thermoplastic fibre composites using the T-RTM-process has been demonstrated in recent years within the framework of research and development projects. The use of the reactive, low-viscosity monomer melt enables the infiltration of semi-finished fibre products, but is very sensitive to external influences. One of the major influencing factors is water, which comes into contact with the materials to be processed in the form of humidity. The water molecules introduced during processing reduce the reactivity of the monomer melt. A reproducible production is not possible without taking into account and compensating the influence of water.
