Abstract
High pressure resin transfer molding is a method for processing continuous fiber reinforced composites at industrial production rates. This paper examines the more common HP-IRTM variant, where the 'I' stands for injection. To achieve a composite with the best mechanical properties, a combination of the fiber, resin and processing parameters must be understood. Two different matrix materials, epoxy and polyurethane, and two different fibers, glass and carbon, are processed on a KraussMaffei HP-RTM system at the Fraunhofer Project Center in London, Ontario, Canada. Several processing parameters are investigated during the manufacturing of these polymer matrix composites including the press force during injection, the press force during cure, and the injection rate. Subsequently, the manufactured parts are characterized and their mechanical properties are evaluated. The results of this study shed light on the critical properties and process settings in HP-RTM production.
