This paper explores the feasibility of using functionally graded carbon nanotube-reinforced composite (FG-CNTRC) in designing bistable plates. Single-walled carbon nanotubes (SWCNTs) in this nanocomposite are assumed to have a functionally graded distribution across the thickness direction following a power law. By varying the distribution type, vo...

... Machinability of a hard material, namely, Altemp HX, was investigated for WEDM process, and RSM was employed for optimizing the process parameters and developed a prediction model with a combination of an artificial neural network and genetic algorithm [26]. Nanocomposite is notable area of research; by using this technology, the wearability of marking paint was improved [27] nanocomposites not only limited to metal matrix but also applicable for polymer composites it is evident that Lead sulfide nanoparticles were utilized to develop the MDMO-PPV polymer film for optical applications [28] and the functionally graded carbon nanotubereinforced composite developed for a biomedical application by [29]. Reference [30] developed nanocomposite coating for preventing blistering or delaminating and for corrosion protection [31]. ...
Nanocomposites are preferred for performance enhancement over micron composites because of their better performance in enhancing the desired properties of the parent material. Nano-silicon carbide and nano-graphite are considered together for reinforcement of Al7075 in this piece of research. Here, the purpose of reinforcement of graphite considered is to improve machinability. The stir casting was employed for fabrication of nanocomposite. The composite matrix includes Al7075 matrix material, reinforcement material of nano-SiC (5 wt.%), and nano-graphite (5 wt.%). Wire cut Electrical Discharge Machining (WEDM) of the synthesized nanocomposite SiC/Gr/Al7075 is considered for investigating the machinability. The objectives of the study are to synthesize the novel nanocomposite and optimize the process parameters to minimize the kerf width during WEDM. The independent variables like choice of wire electrode including the uncoated brass wire, diffused annealed wire, and zinc coated brass wire were considered along with operating parameters like gap voltage, pulse-off time (Toff), and pulse-on time (Ton). The response surface methodology (RSM) is used for designing experiments and analyzing and optimizing independent parameters of WEDM for minimizing the kerf width. Experimental results reveal that the machinability performance of the novel nanocomposite in WEDM with zinc coated brass wire was the best and produced minimum kerf width with the optimized inputs of 117 μs pulse-on time, 60 μs pulse-off time, 160A input current, and 10 volt gap voltage.
