HybridRTM - Quality Controlled Manufacturing of Hybrid Material Composites through Resin Transfer Moulding

Abstract

HybridRTM terms a publicly funded project, which aims at the development of a processing technique for manufacturing of light weight structural components from hybrid materials. In particular, components involving metal as well as fibre-reinforced polymer composite materials are manufactured in a single processing step by means of the resin transfer moulding (RTM) technique. Project activities include material development and characterization, modelling of thermally induced residual stresses, process simulation, mould development as well as model-based process control in order to ensure consistently high component quality. This paper outlines the fundamental idea of the project and summarizes the most important results gained during the first two years of project activities.

Minimum invasive production-related SLS specimen manufacturing for interface characterization of hybrid materials made by RTM

“…In the standard procedure, the interface between the two components is built in a separate gluing step, while in the novel approach, it is realized during the RTM process. This makes the procedure much more productionrelated for the one shot hybrid (OSH)-RTM process [4][5][6].…”

“…The latter case can be applied to fiber-reinforced plastics (FRPs) which can be hybridized with metals for instance. The injection phase of the resin transfer molding (RTM) process can be used to combine the manufacturing step of the FRP and the joining step of the metal and FRP component [4][5][6]. Therefore, the fiber preform and the metal component are placed together in the mold.…”

Influence of processing parameters on quality factors of one-shot hybrid structures made by RTM

“…While the influence of the surface treatment and interface layer onto the mechanical properties of such hybrids was studied by Wang et al [12,13], the impact of variable processing parameters has not been considered yet. As described above, the OSH-RTM process is using the matrix system as an adhesive [12,14,15]. This saves the production step of gluing but also hides some challenges.…”
