“…This effect positively affects the electrical properties since conduction takes place at lower loadings of nanofiller than those involving intimate contact between the nanoparticles [ 140 , 141 ], even if a suitable tunneling distance is necessary to provide conduction; for example, CNTs in polymer matrices have a maximum tunneling distance of 1.8 nm [ 142 ]. The presence of uniformly dispersed nanofillers is, once again, a basic requirement [ 101 ] and a critical loading, the so-called electrical percolation threshold ( Figure 10 ), is needed to obtain electrical conductivity [ 9 , 15 , 17 , 109 , 110 , 127 , 139 , 143 , 144 ]. The percolation threshold is usually achieved using 0.5–1 wt.% loads of nanofiller, but nanoparticles’ functionalization can further decrease the required loading content [ 100 , 102 ].…”

“…The extraordinary chemical and physical properties of a wide variety of experimental nano-epoxies enable a wide range of applications, varying from coatings to structural adhesives, from FRP matrix to electrical/electronic components. Epoxy nanocomposites have found advantageous application in many industrial fields [ 59 , 120 ] such as aerospace [ 114 ], aircraft [ 119 ], automotive [ 33 , 110 ], buildings [ 18 , 67 , 145 , 146 ], electronic devices [ 17 , 86 , 99 , 128 ], sensors [ 90 , 110 , 115 , 127 , 144 ] (even for biomedical applications), anti-static materials [ 9 ], abrasive tools [ 103 ], anti-corrosive coatings (for example in marine environment [ 147 ] or pipes [ 10 ]), and structural applications [ 29 , 68 , 109 ] with self-sensing properties [ 127 ]. Often, the improved properties allow an efficient usage for multifunctional purposes [ 27 , 69 , 148 ].…”

“…Another class of nanostructured epoxies, i.e., the organic–inorganic hybrid one, is introduced, highlighting its strong potential in many applications. Differently from other recent reviews focused on specific properties of the nanocomposites [ 7 , 8 , 9 , 10 ] or individual nanoparticles [ 11 , 12 , 13 ] added to epoxy, a wide-ranging overview of many characteristics and nanofillers has been presented in this paper.

This paper aims at reviewing the works published in the last five years (2016–2020) on polymer nanocomposites based on epoxy resins. The different nanofillers successfully added to epoxies to enhance some of their characteristics, in relation to the nature and the feature of each nanofiller, are illustrated. The organic–inorganic hybrid nanostructured epoxies are also introduced and their strong potential in many applications has been highlighted. The different methods and routes employed for the production of nanofilled/nanostructured epoxies are described. A discussion of the main properties and final performance, which comprise durability, of epoxy nanocomposites, depending on chemical nature, shape, and size of nanoparticles and on their distribution, is presented. It is also shown why an efficient uniform dispersion of the nanofillers in the epoxy matrix, along with strong interfacial interactions with the polymeric network, will guarantee the success of the application for which the nanocomposite is proposed. The mechanisms yielding to the improved properties in comparison to the neat polymer are illustrated. The most important applications in which these new materials can better exploit their uniqueness are finally presented, also evidencing the aspects that limit a wider diffusion.

“…With the rapid development of 3D printing of PEEK and PEEK composite materials, PEEK has widely been adopted for applications in biology, medicine, aerospace, and other fields [ 43 , 44 , 45 , 46 , 47 ]. However, only a handful of studies dealing with the nuclear radiation shielding performances of 3D-printed PEEK and PEEK composite materials have so far been reported.…”

Nuclear energy provides enduring power to space vehicles, but special attention should be paid to radiation shielding during the development and use of nuclear energy systems. In this paper, novel composite materials containing poly-ether-ether-ketone (PEEK) as a substrate and different tungsten contents as a reinforcing agent were developed and tested as shielding for gamma-ray radiation. Shielding test bodies were quickly processed by fused deposition modeling (FDM) 3D printing, and their mechanical, shielding properties of composite materials were evaluated. The results revealed shielding materials with excellent mechanical properties which can further be improved by heat treatment. Under 0.45 MPa load, the heat deflection temperature of PEEK/tungsten (metal) composites was significantly lower than that of PEEK/boron carbide (non-metal) composites. The new shielding materials also demonstrated better shielding of low-energy 137Cs than high-energy 60Co. The gamma-ray shielding rates of test pieces shielding materials made of the same thickness changed exponentially with the tungsten content present in the composite materials. More tungsten led to a better shielding effect. At the same tungsten content, the gamma-ray shielding effect showed a proportional relationship with the thickness of the shielding test bodies, in which thicker test bodies induced better shielding effects. In sum, the integration of 3D printing in the mechanical design and manufacturing of shielding bodies is an effective and promising way for quick processing when considering diverse rays and complex environments. Lighter shielding bodies, at lower costs, can be achieved by structural design in limited space to maximize the material utilization rate and reduce waste.

“…The excellent properties like physical, mechanical, chemical, electrical, thermal, optical, etc., along with the low cost of the composites as compared to the conventional materials facilitated their applications in the above fields. [ 1–9 ] One of the most important characteristics of reinforced polymer composites to be used in the above applications is wear resistance. [ 10–12 ] Kurdi et al revealed that, better is the mechanical properties like, compressive strength, hardness, and impact strength of the polymer composites, higher is the resistance to wear at room temperature.…”

Wear characteristics of glass‐polyester‐based hybrid composites: A parametric analysis using response surface method and fuzzy logic

Marble dust generated during processing of the marble producing rocks is a major solid waste with a detrimental impact on environment. Analysis shows that this waste has constituents having compounds like SiO2, Al2O3, Fe2O3, CaO, MgO, etc., in different proportions. This paper explores on the possible use of waste marble dust as secondary filler in glass‐polyester composites and reports on its dry sliding wear characteristics. Such hybrid composites with unsaturated polyester as the matrix are fabricated by keeping the woven glass fibre loading fixed and by varying the weight fraction of the particulate filler, that is, marble dust through a simple hand layup route. Dry sliding wear trials are conducted under different test conditions as per ASTM G 99‐05 following the L30 model of response surface method (RSM). A parametric appraisal of the wear process is made using RSM and the significant control factors and their interactions influencing the specific wear rates are identified. Scanning electron microscopy of the worn composite surfaces is done to ascertain the wear mechanism. It is found that the presence of marble dust improves the wear resistance of unfilled glass‐polyester composites substantially. Further, prediction of wear rate of the composites for a wide range of filler content and sliding velocities is conducted using RSM and another prediction model based on fuzzy logic and the outcomes are compared.
