Abstract This study reports on silicon nitride (Si3N4) and graphene nanoplatelets binary powder reinforced hybrid titanium composites obtained by a powder metallurgy method. Si3N4 powder was added at 3 wt.% and graphene nanoplatelets were added in various amounts (0.15, 0.30, 0.45, 0.60 wt.%) in the titanium matrix. Density, micro-Vickers hardness, compressive behavior, wear properties and microstructure of the hybrid composites were evaluated. Addition of different percentages of graphene nanoplatelets and 3 wt.% Si3N4 to the titanium matrix composites significantly enhanced mechanical properties. The highest hardness (634 HV) and compressive strength (1458 MPa) values were measured for 0.15 wt.% graphene nanoplatelets and 3 wt.% Si3N4 added titanium hybrid composite. The lowest mass loss and wear rate (Δm = 4 mg, W = 6.1×10–5 mm3 (N m)–1) values were measured for the same 0.15 wt.% graphene nanoplatelets and 3 wt.% Si3N4 added titanium hybrid composite compared with pure Ti.

Machinability Analysis

Aluminium Matrix Composites are extensively used due to their desirable properties like low weight, low cost, high strength to weight ratio, good corrosion resistance, good thermal conductivity and high stiffness. Their applications are diversified in production, thermal, marine and automobile industries. Aluminium is extensively used in ships, aircrafts, cars, electrical wires and household utensils because it is abundant in nature. In the present study, Aluminium alloy Al6061 Hybrid Composites reinforced with Boron carbide and Coconut shell ash are fabricated to replace the individual Aluminium alloy Al6061. For that various tests to determine properties such as strength, hardness, wear and corrosion resistance are conducted on composite samples which make them fit to be used in aircraft window frames by reviewing various literatures. In addition to above, machinability analysis is performed on all the specimens and their surface roughness is measured. Based on the results obtained, we can come to a conclusion that the aluminium composite has superior properties than individual Al6061 alloy.

In this paper, composite and hybrid composite materials were prepared using the hand lay-up method, with carbon, glass, and Kevlar fabrics as the reinforcing materials and epoxy as a matrix. The tensile test was performed to determine the optimal ratio of epoxy resin in carbon fabric/epoxy, glass fabric/epoxy, and Kevlar fabric/epoxy composites in terms of tensile properties. It was found that the optimal ratio of epoxy in terms of tensile properties to impregnate the used Kevlar fabric, glass fabric, and carbon fabric was around 45%wt, 3%wt, and 30 %wt, respectively. The effect of fabric content and stacking sequences, with a fixed epoxy content, on the hybrid composites’ tensile properties were also investigated. The tensile properties of the prepared composites were compared to determine the most favorable preparation conditions for obtaining a hybrid laminate that has high tensile properties and is suitable for a wide range of applications at a low cost.

Purpose The study aims to investigate the influence of fabric hybridization, stacking sequences and matrix materials on the tensile strength and damping behavior of jute/carbon reinforced hybrid composites. Design/methodology/approach The hybrid composites were fabricated with different sequences of fabric plies in epoxy and polyester matrix using a hand layup technique. The tensile and vibration characteristics were evaluated on the hybrid laminated composite models using finite element analysis (FEA), and the results were validated experimentally according to ASTM standards. The surface morphology of the fractured specimens was studied using the scanning electron microscope. Findings The experimental results revealed that the position of jute layers in the hybrid composites has a significant influence on the tensile strength and damping behavior. The hybrid composite with jute fiber at the surface sides and carbon fibers at the middle exhibited higher tensile strength with superior damping properties. Further, it is found that the experimental results are in good coherence with the FEA results. Originality/value The less weight and low-cost hybrid composites were fabricated by incorporating the jute and carbon fabrics in interply configurations. The influences of fabric hybridization, stacking arrangements and matrix materials on the tensile and vibration behavior of jute/carbon hybrid composites have been numerically evaluated and the results were experimentally validated.

Cenosphere is a ceramic-rich industrial waste produced during burning of coal in the thermal power plants. This study deals with the effect of cenosphere as particulate filler on mechanical behaviour of woven bamboo-glass hybrid composites. The hybrid composite consists of bamboo and E-glass fiber as reinforcement and epoxy as matrix. Cenosphere of different weight percentage (0.5, 1, 1.5 and 2 %) was added to the hybrid composite. The samples were tested as per ASTM standards for their mechanical properties to establish the effect of filler content. It is found that the mechanical properties are significantly influenced by addition of waste ceramic filler cenosphere up to 2 wt.% and increases the tensile, flexural and inter-laminar shear strength in comparison to unfilled composite. Finite element analysis is also done using Midas NFX and the simulation results are compared with experimental results. From the results, it has been found that the experimental values obtained from tensile testing and flexure testing nearly matches with finite element values.

Thermoplastic optical polymers have replaced traditional optical glass for many applications, due to their superior optical performance, mechanical characteristics, low cost, and efficient production process. This paper investigates noncontact microembossing technology used for producing microlens arrays made out of PMMA (polymethyl methacrylate), PS (polyStyrene), and PC (polycarbonate) from a quartz mold, with microhole arrays. An array of planoconvex microlenses are formed because of surface tension caused by applying pressure to the edge of a hole at a certain glass transition temperature. We studied the principle of noncontact microembossing techniques using finite element analysis, in addition to the thermal and mechanical properties of the three polymers. Then, the independently developed hot-embossing equipment was used to fabricate microlens arrays on PMMA, PS, and PC sheets. This is a promising technique for fabricating diverse thermoplastic optical polymer microlens array sheets, with a simple technological process and low production costs.

Purpose – The objective of the present investigation is to prepare a Zn–Al matrix (73 wt. per cent Zn + 27 wt. per cent Al) reinforced with SiC and graphite (Gr) hybrid composites by a rapid current sintering technique. Well-known Zn-based alloys are good candidates for load bearing applications. However, some limitations exist in Zn sublimation during casting and solid-state sintering and low-sliding velocity applications. The purpose is to develop new hybrid composites for self-lubricated bearing alloys by the facile production technique of current-activated sintering for these types of hybrid composites at very short sintering periods. Design/methodology/approach – Designing a special power unit for current sintering. The hybrid composites of the Zn–Al matrix were reinforced with 20 vol. per cent SiC and different amounts of Gr (2.5, 5.0, 7.5 and 10 weight per cent) and sintered rapidly by current sintering. Tribological tests for wear behaviors and self-lubrication effect were studied. The authors' approach is mainly to produce low-cost load-bearing materials. Findings – Successful and rapid production of Zn–Al alloy SiC/Gr hybrid composites in this study led to increasing load bearing capacity, decreasing friction coefficient and wear rate and production of good substitutes for conventional bearing applications. Originality/value – A conventional Zn alloy was reinforced with both SiC and Gr particles. This work is original in two ways. It is noted after the literature survey that this alloy is first reinforced with two different types of reinforcements as a hybrid type of composite. Second, the consolidation of this hybrid material was carried out by a direct current for eliminating Zn sublimation and shortening the production time. In tribological applications demanding strength and lubrication requirements, Zn–Al/SiC/Gr hybrid composites were assessed as good substitutes for conventional materials owing to improved wear resistance as a result of combined reinforcement of SiC and Gr particulates.

Abstract Due to the demand in present industrial, aerospace, defense sectors for lightweight high-performance aluminum (Al) particle-reinforced metal matrix composites, the advancement of techniques to fabricate these composites with superior mechanical properties have gained technological interest in the modern world. In this direction, SiC and graphite reinforced AA7075 matrix composite material has been fabricated in this study, through hybrid microwave sintering techniques. The microwave sintering temperatures for the optimized volume fraction composition of AA7075/SiC/graphite hybrid composite has been varied from 400 to 550 ℃ with a step value of 50 ℃. The obtained results showed a superior improvement in the mechanical properties for microwave sintered composites as compared to the conventionally sintered composites. Mechanical properties are found to show increasing trend with increasing microwave sintering temperatures up to 500 ℃, after that, a downfall is observed in their mechanical properties, which can be attributed to the increased average grain size of the composite at 550 ℃. Selection of SiC as primary reinforcement material helped in achieving high mechanical strengths, and through microwave sintering, an increment of 37.2% in tensile, 26.6% in compression, and 16.5% in hardness is achieved. From this investigation, it is also observed that the selection of materials that shows high response to microwaves helps in achieving the enhanced mechanical properties for the hybrid composites processed by microwave sintering techniques.

This study describes a methodological proposal to select composite materials which are suitable to be employed to manufacture pipes that can properly withstand environments subjected to gamma and neutronic radiation. The methodology is used to select, among many others, the optimal composite material whose properties are used afterwards to simulate several pipe sections by finite element analysis, comparing the results with a well-known nuclear-grade steel, WWER 15Kh2MFAA. The most suitable composite material according to the defined criteria is composed of a phenolic resin matrix reinforced with long boron fibres and exhibit great properties to be used in a nuclear reactor environment: good radiation resistance and mechanical properties with a very low density at low cost. It can be concluded that, in some cases, composite material pipes can be a better option than steel ones. Extending the method to be employed in other industries or with other components could be seen as future works.
