“…Similar to increasing average fiber length, improving interfacial adhesion can also have a significant impact on the mechanical performance of FDM-printed parts. There are many studies on improvement of interfacial adhesion in composites via modification of the fiber surface [10,32,33]. Fig.…”

Additive manufacturing is distinguished from traditional manufacturing techniques such as casting and machining by its ability to handle complex shapes with great design flexibility and without the typical waste. Although this technique has been mainly used for rapid prototyping, interest is growing in direct manufacture of actual parts. For wide spread application of 3D additive manufacturing, both techniques and feedstock materials require improvements to meet the mechanical requirements of load-bearing components. Here, we investigated short fiber (0.2 mm to 0.4 mm) reinforced acrylonitrile-butadiene-styrene composites as a feedstock for 3Dprinting in terms of their processibility, microstructure and mechanical performance. The additive components are also compared with traditional compression molded composites. The tensile strength and modulus of 3D-printed samples increased ~115% and ~700%, respectively. 3D-printing yielded samples with very high fiber orientation in the printing direction (up to 91.5 %), whereas, compression molding process yielded samples with significantly lower fiber orientation. Microstructure-mechanical property relationships revealed that although a relatively high porosity is observed in 3D-printed composites as compared to those produced by the conventional compression molding technique, they both exhibited comparable tensile strength and modulus. This phenomenon is explained based on the changes in fiber orientation, dispersion and void formation.

“…Use of fibrillar materials to improve the mechanical properties of polymer resins is an effective approach. Many studies on the use of carbon and glass fibers to improve to mechanical properties of common polymer resins were reported [1][2][3][4][5][6]. Use of bio-based cellulosic fibers ranging from cellulose nanocrystals to microfibrillated cellulose were also reported to improve the mechanical properties of both thermoset and thermoplastic polymers [7].…”

“…Carbon fiber (C‐fiber)‐reinforced carbon/carbon (C/C) and carbon/carbon–silicon carbide (C/C–SiC) composites are gaining increasing market demand for sophisticated and advanced applications such as in aerospace industries, medical appliances, sports accessories, high‐energy brake and clutch systems, and other high‐performance structural equipment due to several advantages over the conventional monolithic materials 1–10 . However, a limitation of C/C composite is that at above 400°C, the composite suffers degradation of properties due to rapid oxidation of carbon 11–13 .…”

“…Although large amount of data are available on the bulk thermo‐mechanical properties of C/C 3–10,24 and C/C–SiC composites, 19–26 the deformation behavior of these composites using nanoindentation is hardly available in the literatures. While some data are available on the local mechanical performance of C/C composites, 6,32–35 to the best of our knowledge, no published data are available on the depth‐sensitive mechanical properties of the C/C–SiC composites.…”

2D carbon fiber (C-fiber)-reinforced carbon/carbon (C/C) composites were prepared by vacuum infiltration with coal-tar pitch followed by carbonization and graphitization in inert atmosphere. Liquid silicon infiltration was done in controlled atmosphere at 16001C to convert the matrix carbon of the C/C composites into silicon carbide. The 2D C/C and carbon/ carbon-silicon carbide (C/C-SiC) composites had density of B1.65 and B2.32 g/cm 3 , respectively with corresponding flexural strength of B70 and B169 MPa, respectively. The local mechanical properties like hardness, Young's modulus, contact pressure, relative stiffness, relative spring back, and indentation energies of the two composites under different loading conditions were measured at an ultra low load of 10 mN using a nanoindentation instrument with a Berkovich indenter. The scatter in the data was treated in terms of the two-parameter Weibull statistical analysis. The maximum characteristic Young's modulus (B16 GPa) and hardness (1.20 GPa) was obtained for the C/C-SiC composites in parallel direction of fabric stacking. The elastic rebounce was also the maximum (0.77) for the C/C-SiC composites when loaded in parallel direction of fabric stacking. The extent of structural anisotropy was higher in the C/C-SiC composite than that of the C/C composite.
