“…In other studies, the influence of the laminate sequence, the type and density of reinforcement and fill patterns on the tensile, compressive and bending behaviour of printed components were analysed [22][23][24][25]. There are also studies that analysed other phenomena such as creep [26], fatigue [27], quasi-static indentation [16], impact resistance [28] and hygromechanical behaviour [17]. In these studies it was observed that the mechanical behaviour of the printed materials was highly conditioned by process-induced defects.…”

Taking advantage of an extended design and manufacturing space for composites, the technology of Fused Filament Fabrication (FFF) of continuous fibre-reinforced thermoplastics shows great potential for the production of the next generation of lightweight structural parts. This novel process is very much under development, and knowledge of the mechanical behaviour of the resulting 3D-printed materials is still limited. In this work, the intra-and inter-laminar behaviours of carbon fibre/polyamide printed laminates were extensively characterised to determine ply elastic and strength properties, as well as interface strength and fracture characteristics. Moreover, the effects of eventual production defects on these properties were analysed, putting in evidence some of the present shortcomings of the FFF process. Such defects include non-homogeneous fibre distribution, large amounts of intra-and interlaminar voids, and weak interlayer bonding, which are likely to be due to insufficient thermo-mechanical consolidation of the material during the FFF process, and have significant influence on the matrix-dominated mechanical properties. As a result, the transverse and interlaminar properties were found to be lower than those obtained through Hot Compression Moulding of an equivalent material. Besides highlighting possible process improvements, the mechanical characterisation carried out in this work promises a significant

“…6 showed similar trends also with tensile and bending test results. Again higher values obtained with the production of dipping+lamination+press method and samples at 40% PA. Caminero et al [12] were used fused deposition modelling technique to reinforce polyamide matrix with continuous fibres and investigated impact behaviour. They found impact strength in the range of 75-275 kJ/m 2 with various glass reinforcement layer thicknesses.…”

Abstract. In this study PA12 was reinforced with E-glass woven fabric by dip-coating. PA12 powder and ethanol suspensions were prepared with ratios at 30, 40 and 50% of powder to obtain different fibre contents. Coated fabrics were laid-up and kept in oven at 60°C to evaporate ethanol. Then it was placed in a compression mould and pressed. Obtained laminates were subjected to tensile, bending and impact tests. Fractured surfaces were observed. It was found that mechanical properties were highest when 40% PA powder used in suspension with dip-coating with additional lamination. Fibre failure and fibre pull-out were observed on fractured surfaces.

Three-Dimensional Printing of Continuous Flax Fiber-Reinforced Thermoplastic Composites by Five-Axis Machine

et al. 2020

A method for printing continuous flax fiber-reinforced plastic (CFFRP) composite parts by five-axis three-dimensional (3D) printer, based on fused filament fabrication (FFF) technology, has been developed. FFF printed parts usually need supporting structures, have a stair step effect, and unfavorable mechanical properties. In order to address these deficiencies, continuous natural fiber prepreg filaments were first manufactured, followed by curved path planning for the model for generation of the G-code, and finally printed by a five-axis 3D printer. The surface quality of printed parts was greatly improved. The tensile strength and modulus of CFFRP increased by 89% and 73%, respectively, compared with polylactic acid (PLA) filaments. The flexural strength and modulus of the 3D-printed CFFRP specimens increased by 211% and 224%, respectively, compared with PLA specimens. The maximal curved bending force load and stiffness of the 3D-printed CFFRP specimens increased by 39% and 115%, respectively, compared with the flat slicing method. Advanced light structures, such as leaf springs, can be designed and manufactured by taking advantage of the favorable properties of these composites, which endow them with significant potential for application in the field of automobiles.
