Abstract

Nowadays, due to the competitive economic scenario, industries ever more need to focus on manufacturing speed, increasing efficiency and steady quality. More industrial sectors see additive manufacturing (AM) as a possible way to enhance their processes and increase production efficiency. Thanks to its versatility the Fused Deposition Modelling (FDM), also known as Fused Filament Fabrication (FFF) technique, is one the most attractive processes in Industry 4.0 paradigm. This technique, thanks to its low-cost, is spreading widely in industrial sectors, from biomedical to aerospace to cite some. In this frame a valid solution is to use composite materials Among many, particular attention is paid to thermoplastic systems based on polyether-ether-ketone (PEEK) reinforced with short carbon fibre (CF). The PEEK is a high-performance semi-crystalline thermoplastic polymer that belongs to the polyaryl-ether-ketone family (PAEK). 3D printing, being a novel technology, it must be validated by understanding the behaviours of components and structures. At this purpose, we used different optical techniques for analysing advanced short fibre composites realized by 3D printing. Different CFR-PEEK samples with short carbon fibre at 10% by weight were realized by the FFF technique and characterized in terms of failure mode and mechanical behaviour. Optical tools have been used to retrieve full-field data and expand information about the mechanical behaviour of the investigated material, i.e. 2D Digital Image Correlation (2D-DIC) and Electronic Speckle Pattern Interferometry (ESPI), Optical Microscopy (OM) and Scanning Electron Microscopy (SEM).
