“…Composites are materials consist of two or more different materials used for applications where the constituent materials could not be utilized individually. These composites can be in particle-reinforced, laminated, or fiber-reinforced form [6,7]. Along with this, some researchers are also exploring the combination of printing materials i.e., ABS-PC, PLA-PC, PE-PP, etc, as well as other composites such as ceramic composites, metal matrix composites, natural fiber reinforced composites, and polymer matrix composites to search for its good commercial and market success.…”

Additive manufacturing (AM) technology has gained significant popularity, among which Fused Deposition Modeling (FDM) has emerged as the predominant technique for 3D printing. FDM offers the unique ability to achieve the desired and tailored engineering properties required for specific applications. This experimental study investigates the influence of varying FDM process parameters on the mechanical properties and highlights the optimal set of parameters for better tensile strength for a bi-layered composite of PLA-ABS (polylactic acid and acrylonitrile butadiene styrene). Also, it investigates the most-to-least influential printing parameters. Four process parameters were played out i.e., Infill density (50%, 75%, and 100%), number of layers (20,25 and 30), printing speed (20mm/sec, 40mm/sec, and 60mm/sec), and bed temperature (90◦C, 95◦C, and 100◦C), while keeping other parameters constant. Taguchi optimization technique was used for optimization and experiments were designed according to Taguchi orthogonal array L9 (3 4). After printing, the samples were evaluated for tensile properties and the results were analyzed. It is found that the infill density is the most influential parameter while bed temperature is the least influential. Infill density of 75%, 30 layers per part, a printing speed of 20mm/sec, and a bed temperature of 100◦C are the optimal set of parameters for better tensile strength. Alongside, percent elongation, printing time, and strength-to-weight ratio were also analyzed and correlated.

“…This increase in mechanical strength can be mainly due to heat generated during FSP. At lower traverse speed (40 mm min −1 ), heat generated due to friction will be comparatively higher when compared with 80 mm min −1 traverse speed [38,40]. Higher frictional heat generated during FSP of copper surface composites dispersed with hybrid ceramic particles will lead to softening of copper substrate henceforth declining the mechanical strength.…”

This research deals with investigating the effects of amount of hybrid reinforcement, rotational speed and traverse speed on the mechanical and wear characteristics of copper surface composites fabricated via friction stir processing. Aluminum oxide and boron carbide at 1:1 ratio was dispersed onto copper substrate at various volume fractions (5, 10 and 15 vol. %) at different traverse speed (40, 60 and 80 mm/min) and rotational speed (800, 950 and 1300 rpm). Microstructural characterization of developed copper surface composites dispersed with varying volume fraction of hybrid reinforcement proved reduction in grain size and homogenous distribution of ceramic particles. Results stated that the percentage of particles dispersed, traverse speed and rotational speed have high impact in defining the property of developed copper surface composites. A positive trend in mechanical strength was observed throughout the study. Increase in hybrid reinforcement dispersion and traverse speed increases the microhardness value of developed surface composites while increase in rotational speed leads to reduction in microhardness value.

“…Hence, the mechanical properties of MMCs increase with an increase in the volume fraction of the hybrid reinforcement particles of up to 10%. The microstructure was noticeably influenced by the stirring action of the pin and the frictional heat factors generated during FSP [44].…”

The present study focuses on investigating the effect of reinforcement on the microstructure and mechanical properties of friction-stir-processed magnesium hybrid composites. The groove width (0, 0.7, 1.1, 1.7, and 2.3 mm) of the Magnesium AZ31 plates was varied by varying the volume fractions (0, 5, 10, 15, and 20 vol%) of Silicon Carbide (SiC), Titanium Carbide (TiC), and Graphite (Gr) particle reinforcements in the hybrid composite. Single-pass processing was suspended using a cylindrical tool shoulder with a rotational speed, transverse velocity, and axial pressure of 1000 rpm, 30 mm min−1, and 6 kN, respectively. The optical micrograph clearly shows that a non-cluster zone (reinforcement particles are uniformly distributed without agglomeration) was identified in the processed region of the least concentrated composites. The results revealed that a peak tensile strength of 293.546 ± 5.12 MPa was attained for the combination of 10 vol% composites, and a Vickers hardness number of 86.53 HV was achieved for the 20 vol.% composites. The fracture surface morphology was analyzed using a Scanning Electron Microscope (SEM). The mode of tensile fractography was ductile for the least composite and transformed into a brittle mode of failure with the addition of reinforcements.
