“…Concrete and cement which are most generally used as construction and building materials, respectively, have posed various limitations to the development of novel structures globally, while steel has also been disappointed under certain conditions. Some of the shortcomings of these conventional materials are that cement production gives rise to serious environmental concerns as one tonne of cement production generates about one ton of carbon dioxide and also deteriorates quickly at the outer surface when exposed to alkaline or acid environment [55]. Furthermore, cement concrete exhibits high porosity, cavitation, low flexural strength, low abrasive resistance, low tensile strength, longer setting time, low durability, etc.…”

Right from the early days, polymer materials have been discovered as being beneficial for various applications but a poor understanding of these materials greatly handicapped their usage. However, with a change in this trend, polymer materials have gradually displaced other materials in most applications. In recent times, due to improved research and knowledge, polymer-based materials are the first choice materials for several applications and are now replacing other materials rapidly. More advanced materials from polymers are being developed daily as a substitute for other materials even in areas where polymers are considered not to be suitable in the time past. More recently, polymers have replaced metals and ceramics in applications like constructions, aerospace, automobiles, and medical. It is no doubt that this trend will continue due to the inherent properties of polymers and sustainability potential. Today, most of the limitations of polymers are being taken care of in the formulation of composite materials. Besides, the adaptation to positive environmental influence is being handled by scientists and researchers. Hence, this review reveals core areas of application of polymer-based composites and the significance of these materials to the advancement of humanity.

“…Also, it is noteworthy to mention that in the development of polymer concrete, epoxy resin is mostly used as the binder while a broader choice of materials is used as fillers. They include palm oil fuel ash, PET fibers, silica fume, bagasse ash, fly ash, marble waste, calcium carbonate, etc [55].…”

“…In general, the tensile strength, flexural strength, and deformation properties of PMM and PMC are relatively higher compared with the conventional cement-based materials [ 38 , 39 ]. It has been reported that the improvement of the tensile and flexural strength depends mainly on the polymer content rather than the water–cement ratio [ 40 ]. This phenomenon could be explained by the excellent tensile properties of polymer films and the forming of the polymer–cement co-matrix [ 17 ].…”

In this study, an analysis of the influence of polymer modification on the mechanical behavior, porosity, and microstructure of mortar is carried out. Epoxy latexes contents of 5%, 10%, 15%, and 20% of cement were employed in the preparation of cement mortars based on the same workability. The specimens were subjected to dry, wet, and wet–dry curing regimes. Compressive strength, flexural strength, Mercury intrusion porosimetry (MIP), and scanning electronic microscope (SEM) tests were conducted to analyze the effect of epoxy latexes on the mechanical property and porosity of modified mortars. Based on the compressive strength test results, a quantitative method was established to calculated the degree of hydration and polymerization. The results show that the mechanical behavior and porosity property of epoxy latexes modified mortar are influenced by the degree of hydration, the degree of polymerization, and the volume changing effect of mortar. The polymerization of epoxy latexes could improve the flexural strength of the mortar. The macropores of specimens tended to decrease with the increase of the degree of epoxy latexes polymerization and cement hydration. In practical engineering, it is necessary to ensure the degree of hydration and increase the polymerization rate. Thus, the wet–dry curing regime is recommended.

“…Recently, replacing metallic machine parts with composite material has been seen as a potential alternative to various issues, including high metal costs, rusting, and the weight of the components. In the modern machining industry, composite materials that possess similar or even enhanced physical and mechanical properties compared to metals are highly encouraged [1][2][3]. Polymer composite materials (PCMs) are recognized as a group of difficult-to-machine materials [4].…”

“…The development of light-weight PCMs plays a significant role in aviation and many critical industrial applications. These materials are economically efficient and reduce the CO 2 emission load [ 1 ]. The binders used in PCM have good strengths and are heat resistant, resulting in high elastic strength and operational stability.…”

Analysis of Wire-Cut Electro Discharge Machining of Polymer Composite Materials

et al. 2021

This study presents the analysis of wire-cut electro-discharge machining (WIRE-EDM) of polymer composite material (PCM). The conductivity of the workpiece is improved by using 1 mm thick titanium plates (layers) sandwiched on the PCM. Input process parameters selected are variable voltage (50–100 V), pulse duration (5–15 μs), and pause time (10–50 μs), while the cut-width (kerf) is recognized as an output parameter. Experimentation was carried out by following the central composition design (CCD) design matrix. Analysis of variance was applied to investigate the effect of process parameters on the cut-width of the PCM parts and develop the theoretical model. The results demonstrated that voltage and pulse duration significantly affect the cut-width accuracy of PCM. Furthermore, the theoretical model of machining is developed and illustrates the efficacy within the acceptable range. Finally, it is concluded that the model is an excellent way to successfully estimate the correction factors to machine complex-shaped PCM parts.
