“…SiO 2 , Al 2 O 3 and Fe 2 O 3 in the reinforcement produce an oxide layer. These oxide layers act as self-lubrication properties and thus reduce SWR at higher loads (Manikandan et al , 2020; Venkatesh and Deoghare, 2021). The rate of material removal increases, and COF decreases as the Wt.% of CS increases.…”

Purpose This study aims to deal with developing composite filaments and investigating the tribological behavior of additively manufactured syntactic foam composites. The primary objective is to examine the suitability of the cenosphere (CS; 0–30 Wt.%) to develop a high-quality lightweight composite structure with improved abrasion strength. Design/methodology/approach CS/polyethylene terephthalate glycol (PETG) composite feedstock filaments under optimized extrusion conditions were developed, and a fused filament fabrication process was used to prepare CS-filled PETG composite structures under optimal printing conditions. Significant parameters such as CS (0–30 Wt.%), sliding speed (200–800 rpm) and typical load (10–40 N) were used to minimize the dry sliding wear rate and coefficient of friction for developed composites. Findings The friction coefficient and specific wear rate (SWR) are most affected by the CS weight percentage and applied load, respectively. However, nozzle temperature has the least effect on the friction coefficient and SWR. A mathematical model predicts the composite material’s SWR and coefficient of friction with 87.5% and 95.2% accuracy, respectively. Practical implications Because of their tailorable physical and mechanical properties, CS/PETG lightweight composite structures can be used in low-density and damage-tolerance applications. Social implications CS, an industrial waste material, is used to develop lightweight syntactic foam composites for advanced engineering applications. Originality/value CS-reinforced PETG composite filaments were developed to fabricate ultra-light composite structures through a 3D printing routine.

“…The shells were dried for 24 h and then allowed for the ball milling process in RESTECH 100 planetary ball mill for 30 min at 450 rpm. 16,17 To separate the APS of less than 40 µm, the shell powders were sieved by utilizing a mechanically driven sieving machine (Retsch AS200 basic, Germany). The sieved powders and SiC particles were reinforced in the aluminum matrix to fabricate the composite.…”

This study emphasizes the synthesis of hybrid aluminum composite reinforced with SiC and Snail Shell (S-Shell) particles through the powder metallurgy technique. The hybrid composite corresponding to the optimized volume fraction of SiC and Snail shell powder (Al-6%SiC-6%S-Shell) was subjected to microwave-assisted sintering (MAS) by varying the sintering temperatures from 400°C to 550°C in steps of 50°C. Results concluded that microwave-sintered composites show superior mechanical characteristics than the composites sintered through conventional sintering techniques. The maximum ultimate tensile strength (U.T.S) of 316 MPa, and compression strength of 396 MPa were obtained for microwave sintered Al-6%SiC-6%Snail shell powder composite sintered at 500°C. However, increasing the sintering temperature above 500°C leads to a reduction in U.T.S and Compression strength due to the formation of coarse grains by absorbing the microwaves at higher temperatures. The U.T.S, Compression strength and Vickers hardness of the microwave sintered Al-6%SiC-6%Snail shell powder hybrid composite sintered at 500°C was enhanced by 42.08%, 42.4%, and 35.5% compared to conventionally sintered hybrid composite. The grain size was found to be increased with an increase in microwave sintering temperature due to the enhancement in the absorption capability of the microwaves with the temperature rise. The results of this study also suggest that choosing materials with a high microwave response helps to achieve improved mechanical properties for microwave-sintered composites.

“…however, increasing the sintering temperature beyond 550°C is prone to decrement in hardness from 97 hv to 85 hv. the presence of difference in linear thermal expansion coefficient among the generated agglomerations and aluminium matrix leads to uneven expansions of the interface particles and leads to void generation along the grain boundaries and reduces the hardness of the composite at the higher sintering temperatures [35,36]. fig.…”
