Mechanical characterisation of Aerosil-polycarbonate-based ceramic nanocomposites: 3D printing versus injection moulding technology

Abstract

The 3D printing of composite materials especially, nanocomposites, is an essential step in exploring new perspectives for the applications of organic matrix composite materials for industrial applications. In this work, the effect of ceramic nanofillers on the mechanical properties of a thermoplastic matrix is studied using different wt% of nanofillers (AEROSIL). The results showed that the increase in the wt% of AEROSIL resulted in an increase in the mechanical properties in terms of hardness, stiffness, ductility, and tensile strength. Moreover, these samples were 3D printed and were compared with the samples prepared by conventional injection moulding. The comparison characterized the influence of the manufacturing method on the mechanical performance of materials. Although there was very little behavior difference in both samples, the 3D-printed samples showed a weight reduction. This has broadened the possible applications of this material and technique in areas where weight is of utmost significance.

3D Printing of a Tidal Turbine Blade Using Two Methods of SLS and FFF of a Reinforced PA12 Composite: A Comparative Study

“…The significance of these compact marine turbines lies in their cost-effectiveness, simplified manufacturing processes, and accelerated production, thereby supporting isolated communities in their quest for efficient electricity generation. The fabrication of such turbines can be achieved through advanced techniques like 3D printing or additive manufacturing (AM) [8][9][10] , facilitating the automated construction of 3D components by layering base materials and overcoming limitations in molding fabrication methods [11,12] . Rouway et al [13] investigate the viability of employing 3D printing technology, specifically Selective Laser Sintering (SLS), to create compact tidal turbine blades suitable for deployment in rural regions.…”
