“…The Pareto chart displayed in Fig. 14 was 13 Interaction plot for the mould temperature and resin temperature affecting the bending modulus E f created without using the elimination technique otherwise all parameters of the model would be eliminated. There are two ways to describe the absence of a significant influence on the apparent ILSS by the processing parameters.…”

“…There are different methods available to enhance bonding quality such as corona treatment, sand blasting or etching [9][10][11]. 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 paper is dealing with the influence of processing parameters for manufacturing of steel-carbon-fiber-reinforced-plastic (CFRP) hybrid plates by using the one-shot-hybrid resin-transfer-moulding (OSH-RTM) process. A design of experiments study was carried out. The quality of the manufactured parts was quantified by the bending modulus, the apparent interlaminar shear strength (ILSS), the maximum deflection and the density of the CFRP. The following changeable processing parameters were chosen: mould temperature, resin temperature, change in mass flow and maximum injection pressure. It is shown that the mould temperature and the change in mass flow show significant impact on the flexural modulus, density and maximum deflection of the plate while there is no significant impact on the apparent ILSS. Furthermore, the interaction between the mould temperature and resin temperature is having an influence on the flexural modulus and density.

“…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.…”

This work shows a new way of single lap shear specimen production for hybrid metal-composite materials, which can be used to characterize process-induced interface property variations. Due to this special procedure, the specimen manufacturing can be done production-related and with a homogenization of the thermal stresses occurring in the joint area of the hybrid at each specimen. The exemption process of the specimen is kept in a minimum invasive way, not affecting the interface in the tested zone. The influence of the metal surface structure specifically created by micro form milling as well as the influence of the curing temperature on the maximum shear strength of the interface, were investigated. Finally, the driving failure mechanisms were identified and described.

“…Extreme lightweight packages, as a combination of specific metallic alloys and highperformance composites for structural parts, are the most relevant to achieve a consistent weight reduction (Wang et al, 2016), even if they imply a superior cost. This is a big challenge for Automotive industry: respect to the Aerospace one, where composites are largely used, Automotive has unique limiting factors including surface finish and impact performance requirements (Elmarakbi et al, 2016), manufacturing cycle time, joining manufacturing infrastructure and production volumes.…”

Based on Pininfarina Nido EV concept, EVolution aims to reduce the vehicle weight through new materials and process technologies, focused on five demonstrators: underbody, front crossbeam, mechanical subframe, shotgun system and door. This paper refers to body structure design strategies using new composite, Al materials and enabled technologies, focusing in particular on demonstrators design and manufacturing. The new front crossbeam geometry of the front shell is adapted starting from the Nanotough design, while the rear shell is specific for EVolution. The subframe demonstrator is redesigned to fulfil mechanical requirements of the part and manufacturing feasibility either. The EVolution door concept consists of two semistructural Evolution FP7 funded project: body structure design strategies 253 composite skins including a structural Al frame. The underbody is conceived through an integrated approach, optimising each element for its function. The shotgun component is designed to link parts obtained with different manufacturing technologies and several aluminium alloys in one single component: the structural node demonstrator.
