“…The effect of masterbatch quality on the properties of a PP hybrid composite was studied by diluting the selected masterbatches, BMB220-1 and LMB330-1, in a PP/GF composite also containing MAPP, according to a manufacturing recipe for automotive parts [ 30 ]. The Leistritz LSM 30.34 co-rotating twin-screw extruder was used for the dilution due to its mild configuration, which protects GF from severe breaking.…”

Masterbatches from a linear poly[styrene-b-(ethylene-co-butylene)-b-styrene] (SEBS) and halloysite nanotubes (HNT-QM) were obtained in different conditions of temperature and shear using two co-rotating twin-screw extruders. The influence of screw configuration and melt processing conditions on the morpho-structural, thermal and mechanical properties of masterbatches at macro and nanoscale was studied. A good dispersion of halloysite nanotubes and better thermal stability and tensile and nanomechanical properties were obtained at a lower temperature profile and higher screw speed. The effect of masterbatches, the best and worst alternatives, on the properties of a polypropylene (PP)–glass fiber (GF) composite was also evaluated. Double hardness, tensile strength and modulus and four times higher impact strength were obtained for PP/GF composites containing masterbatches compared to pristine PP. However, the masterbatch with the best properties led further to enhanced mechanical properties of the PP/GF composite. A clear difference between the effects of the two masterbatches was obtained by nanoindentation and nanoscratch tests. These analyses proved to be useful for the design of polymer composites for automotive parts, such as bumpers or door panels. This study demonstrated that setting-up the correct processing conditions is very important to obtain the desired properties for automotive applications.

“…The masterbatch components, SEBS and HNT-QM, in a ratio of 20:1, as established by a patented procedure [ 30 ], were mixed in a rotating mixer at room temperature for 30 min and then introduced in the main hopper of the extruder. Two temperature profiles from hopper to die were considered on both extruders:…”

“…Therefore, the composition of the new polymeric material was specially tailored using the advanced material PP with 30-50% GF in which a special nanosilicate was added. The nanosilicate was evenly embedded into a thermoplastic elastomer matrix to obtain a smart masterbatch (Drozdov et al, 2014;Vuluga et al, 2014Vuluga et al, , 2016. The masterbach composition and the optimum ratio between components enable its use directly in the extrusion-injection process.…”

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.
