“…Multiscale polymer composites containing simultaneously more than one discontinuous phase in the form of a microfiller and a nanofiller dispersed in a continuous polymer matrix are of increasing interest [5][6][7][8][9][10][11]. Of particular interest in terms of novel properties are composites where the micro-and nanofillers are carbon structures [12,13].…”

To date, there has been limited information in the literature on the application of carbon fibre-carbon nanotube systems for the modification of poly(vinyl chloride) (PVC) matrixes by micro- and nanometric fillers and an evaluation of the properties of the unique materials produced. This paper presents the results of newly designed unique multiscale composites. The advantages of the simultaneous use of carbon fibres (CFs) and carbon nanotubes (CNTs) in PVC modification are discussed. To increase the dispersibility of the nanofiller, CFs together with nanotubes were subjected to a sonication process. The resulting material was introduced into PVC blends, which were processed by extrusion. The ratio of components in the hybrid filler with CF_CNT was 20:1, and its proportion in the PVC matrix was 1, 5, and 10 wt.%, respectively. Comparatively, PVC composites modified only with carbon fibres were obtained. The structure, thermal, electrical, and mechanical properties and swelling resistance of the composites were studied. The study showed a favourable homogeneous dispersion of nanotubes in the PVC matrix. This enabled effective modification of the structure at the nanometric level and the formation of an interpenetrating network of well-dispersed hybrid filler, as evidenced by a decrease in volume resistivity and improvement in swelling resistance, as well as an increase in glass transition temperature in the case of PVC/CF_CNT composites.

“…Continuum modeling is commonly used to analyze nano and micro scales in multiscale composites, while the principle of micromechanical models is applied for modeling meso and macro scales. A stochastic multiscale approach has also been recognized as suitable for predicting elastic properties in multiscale composites subjected to static and dynamic loadings [ 62 ].…”

This paper presents an experimental investigation of nanocomposites composed of three ratios of epoxy/graphene nanoplatelets (GNPs) by weight. The 0.1, 0.2, and 0.3 wt.% specimens were carefully manufactured, and their mechanical and thermal conductivity properties were examined. The tensile strength and modulus of epoxy/GNPs were enhanced by the large surface area of graphene nanoplatelets, causing crack deflection that created new fracture fronts and friction because of the rough fracture surface. However, the compressive strength was gradually reduced as GNP loading percentages increased. This was probably due to severe plastic yielding on the epoxy, leading to catastrophic axial splitting caused by premature fractures. Furthermore, the highest thermal conductivity was 0.1283 W/m-K, representing a 20.92% improvement over neat epoxy (0.1061 W/m-K) when 0.3 wt.% GNPs were added to the epoxy. This was because of efficient heat propagation in the GNPs due to electron movement through percolative paths. The tensile failure mode in epoxy/GNP nanocomposites showed a few deflected and bifurcated rough cracks and brittle, dimple-like fractures. Contrarily, compressive failure mode in GNP-added epoxy showed plastic flexural buckling and brittle large-axial splitting. The epoxy/GNP nanocomposites were considered a damage-tolerant material.

“…When solving applied problems directly related to the development of new PMCs and technologies for their production, it is often more efficient to use semi‐empirical models with fitting parameters. The foregoing fully applies to the description of the elastic properties of both traditional (micrometer fillers) 25 and hybrid nano‐ and multiscale PMCs 26 . At the same time, in the scientific literature there are a few works describing size effects in PMCs with micrometer‐sized fillers.…”

A semi‐empirical model of the influence of the size of micrometer fillers on the elastic moduli of polymer‐matrix composites is proposed. The modulus of elasticity of the composite is the sum of the modulus of elasticity at infinite filler size and an exponential function depending on filler size. The calculated dependencies contain two empirical parameters, and the model is identified based on the results of an experiment with two filler sizes. Composites with the minimum and maximum filler size are selected among the studied options. The scope of application of the model was studied by varying the filler size and boundary values of Young's modulus and eight grades of polymer‐matrix composites. The filler size varied over a wide range from 3.5 to 140 μm. The range of changes in the boundary values was also significant, and depending on the brand of the composite, it was 7%–43% of Young's modulus . For all variants of particle size and the range of changes in the boundary values of the Young's modulus, the calculation results are in good agreement with the experimental data.Highlights Semi‐empirical model of the effect of filler size on the elastic moduli polymer composites.
