“…In the final stage, crack propagation occurs at the fiber, and localized fractures occur [ 68 ]. Travieso-Rodriguez et al [ 69 ] utilized the Taguchi design of experiments to study the fatigue performance of wood-PLA-based composite material. The study revealed the that 75% infill density, a 0.7 mm nozzle diameter, and a 0.4 mm layer height was the optimal combination.…”

Composite materials are a combination of two or more types of materials used to enhance the mechanical and structural properties of engineering products. When fibers are mixed in the polymeric matrix, the composite material is known as fiber-reinforced polymer (FRP). FRP materials are widely used in structural applications related to defense, automotive, aerospace, and sports-based industries. These materials are used in producing lightweight components with high tensile strength and rigidity. The fiber component in fiber-reinforced polymers provides the desired strength-to-weight ratio; however, the polymer portion costs less, and the process of making the matrix is quite straightforward. There is a high demand in industrial sectors, such as defense and military, aerospace, automotive, biomedical and sports, to manufacture these fiber-reinforced polymers using 3D printing and additive manufacturing technologies. FRP composites are used in diversified applications such as military vehicles, shelters, war fighting safety equipment, fighter aircrafts, naval ships, and submarine structures. Techniques to fabricate composite materials, degrade the weight-to-strength ratio and the tensile strength of the components, and they can play a critical role towards the service life of the components. Fused deposition modeling (FDM) is a technique for 3D printing that allows layered fabrication of parts using thermoplastic composites. Complex shape and geometry with enhanced mechanical properties can be obtained using this technique. This paper highlights the limitations in the development of FRPs and challenges associated with their mechanical properties. The future prospects of carbon fiber (CF) and polymeric matrixes are also mentioned in this study. The study also highlights different areas requiring further investigation in FDM-assisted 3D printing. The available literature on FRP composites is focused only on describing the properties of the product and the potential applications for it. It has been observed that scientific knowledge has gaps when it comes to predicting the performance of FRP composite parts fabricated under 3D printing (FDM) techniques. The mechanical properties of 3D-printed FRPs were studied so that a correlation between the 3D printing method could be established. This review paper will be helpful for researchers, scientists, manufacturers, etc., working in the area of FDM-assisted 3D printing of FRPs.

“…However, PLA has a low tenacity, which is limiting in high mechanical demand applications, making improvement of these properties a desirable pursuit. The benefit of incorporating natural fibers into PLA for additive manufacturing has increased in recent years, mainly due to sustainability issues 8,9 . For example, natural waste materials can be used as reinforcements for composites, extending the life cycle of the waste, making the materials sustainable, biodegradable, and environmentally friendly 10,11 .…”

“…For example, natural waste materials can be used as reinforcements for composites, extending the life cycle of the waste, making the materials sustainable, biodegradable, and environmentally friendly 10,11 . PLA composites reinforced with natural fibers, such as wood, kenaf, and keratin, have displayed notable thermal and mechanical properties 9–13 . This has allowed the development of some materials that already exist on the market, such as biodegradable urns from PLA and flax, PLA‐kenaf mobile phone cases, and in the automotive industry, the development and application of covers for replacement tires from PLA‐kenaf fiber 14 .…”

In this research, additive manufacturing of polylactic acid (PLA) reinforced with keratin was studied. Keratin was obtained from Angora rabbit hair and modified with NaOH. Scanning electron microscopy (SEM) images showed that the modified surfaces were rougher than untreated surfaces. Furthermore, SEM images in the composites' fracture regions showed surface changes, associated with the nature of the reinforcement. Likewise, thermomechanical properties of the composites were attributed to the nature of the reinforcement and the type of keratin. Besides, the 3D printed composites showed higher thermal conductivity values than PLA with the addition of keratin. Cytotoxicity tests revealed an improvement in cell growth compared to the control and PLA. These results are meaningful toward the development of high thermal conductors and biocompatible composites with applications in different fields, where the use of only natural polymers is necessary.

“…Recently, agricultural residues have been used as a loading material for 3D printing [ 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 ] as they reduce warping [ 54 , 55 , 56 , 57 ], enhance printing directionality [ 58 , 59 , 60 ], and display high specific mechanical properties [ 61 , 62 , 63 ]. However, in FFF there are some standing issues such as residues’ agglomeration, viscosity variations, high porosity, low thermal stability [ 64 ], and non-uniform physical and mechanical properties [ 61 ].…”

Development and Characterization of Rice Husk and Recycled Polypropylene Composite Filaments for 3D Printing

et al. 2021

Nowadays the use of natural fiber composites has gained significant interest due to their low density, high availability, and low cost. The present study explores the development of sustainable 3D printing filaments based on rice husk (RH), an agricultural residue, and recycled polypropylene (rPP) and the influence of fiber weight ratio on physical, thermal, mechanical, and morphological properties of 3D printing parts. Thermogravimetric analysis revealed that the composite’s degradation process started earlier than for the neat rPP due to the lignocellulosic fiber components. Mechanical tests showed that tensile strength increased when using a raster angle of 0° than specimens printed at 90°, due to the weaker inter-layer bonding compared to in-layer. Furthermore, inter layer bonding tensile strength was similar for all tested materials. Scanning electron microscope (SEM) images revealed the limited interaction between the untreated fiber and matrix, which led to reduced tensile properties. However, during the printing process, composites presented lower warping than printed neat rPP. Thus, 3D printable ecofriendly natural fiber composite filaments with low density and low cost can be developed and used for 3D printing applications, contributing to reduce the impact of plastic and agricultural waste.
