“…With the experiment of Akhoundi et al [ 182 ], they noticed that a continuous glass fibre-reinforced composite with PLA matrix exhibited higher tensile strength, with a 49% fibre volume fraction and rectangular infill pattern. To study the effect of Nylon fill and the tensile properties of 3D printed composites with different concentric rings and layers, Hui Mei et al [ 183 ] conducted research on continuous fibre-reinforced composites of carbon, Kevlar and glass. They developed five types of specimens with different combinations.…”

FDM-Based 3D Printing of Polymer and Associated Composite: A Review on Mechanical Properties, Defects and Treatments

2020

Fused deposition modelling (FDM) is one of the fastest-growing additive manufacturing methods used in printing fibre-reinforced composites (FRC). The performances of the resulting printed parts are limited compared to those by other manufacturing methods due to their inherent defects. Hence, the effort to develop treatment methods to overcome these drawbacks has accelerated during the past few years. The main focus of this study is to review the impact of those defects on the mechanical performance of FRC and therefore to discuss the available treatment methods to eliminate or minimize them in order to enhance the functional properties of the printed parts. As FRC is a combination of polymer matrix material and continuous or short reinforcing fibres, this review will thoroughly discuss both thermoplastic polymers and FRCs printed via FDM technology, including the effect of printing parameters such as layer thickness, infill pattern, raster angle and fibre orientation. The most common defects on printed parts, in particular, the void formation, surface roughness and poor bonding between fibre and matrix, are explored. An inclusive discussion on the effectiveness of chemical, laser, heat and ultrasound treatments to minimize these drawbacks is provided by this review.

“…On the other hand, all this information is very important for designing and characterizing a composite part as well as predicting the mechanical properties. A number of research works have been published that used the Mark Two printer, and few of them examined only a few of these issues that were related to their respective work [10][11][12][13][14][15][16][17].…”

The Road to Improved Fiber-Reinforced 3D Printing Technology

Three-dimensional printing (3DP) is at the forefront of the disruptive innovations adding a new dimension in the material fabrication process with numerous design flexibilities. Especially, the ability to reinforce the plastic matrix with nanofiber, microfiber, chopped fiber and continuous fiber has put the technology beyond imagination in terms of multidimensional applications. In this technical paper, fiber and polymer filaments used by the commercial 3D printers to develop fiber-reinforced composites are characterized to discover the unknown manufacturing specifications such as fiber–polymer distribution and fiber volume fraction that have direct practical implications in determining and tuning composites’ properties and their applications. Additionally, the capabilities and limitations of 3D printing software to process materials and control print parameters in relation to print quality, structural integrity and properties of printed composites are discussed. The work in this paper aims to present constructive evaluation and criticism of the current technology along with its pros and cons in order to guide prospective users and 3D printing equipment manufacturers on improvements, as well as identify the potential avenues of development of the next generation 3D printed fiber-reinforced composites.

“…The mechanical characterisation of the printed CCFRP was also performed for different load cases: tension [15,16,[18][19][20], compression [19], in-plane shear [19,20] and interlaminar shear [21]. 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].…”

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
