“…Frequently, researchers obtain the required magnetic, electrical and microwave properties by preparing the HF-based composite [ 2 , 4 , 7 ]. The HF/polymer composite prepared by thermal pressing or dispersion of HF powders in polymers with high electrical permittivity is the most interesting from a practical standpoint [ 24 , 25 ]. Polyvinylidene fluoride, or PVDF, is obtained by polymerization of vinylidene fluoride (CH 2 =CF 2 ).…”

Binary and ternary composites (CM) based on M-type hexaferrite (HF), polymer matrix (PVDF) and carbon nanomaterials (quasi-one-dimensional carbon nanotubes—CNT and quasi-two-dimensional carbon nanoflakes—CNF) were prepared and investigated for establishing the impact of the different nanosized carbon on magnetic and electrodynamic properties. The ratio between HF and PVDF in HF + PVDF composite was fixed (85 wt% HF and 15 wt% PVDF). The concentration of CNT and CNF in CM was fixed (5 wt% from total HF + PVDF weight). The phase composition and microstructural features were investigated using XRD and SEM, respectively. It was observed that CM contains single-phase HF, γ- and β-PVDF and carbon nanomaterials. Thus, we produced composites that consist of mixed different phases (organic insulator matrix—PDVF; functional magnetic fillers—HF and highly electroconductive additives—CNT/CNF) in the required ratio. VSM data demonstrate that the main contribution in main magnetic characteristics belongs to magnetic fillers (HF). The principal difference in magnetic and electrodynamic properties was shown for CNT- and CNF-based composites. That confirms that the shape of nanosized carbon nanomaterials impact on physical properties of the ternary composited-based magnetic fillers in polymer dielectric matrix.

“…The presented method should have high precision, be simple and could be done with minimum costs. More recently, several theoretical and experimental research works with CNTs as reinforcing fibers have been conducted to determine mechanical and electrical properties of nanotube-based composites [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27].…”

In this paper, a range of matrix materials from polymer to metal matrix were considered which have extensive applications in various industries. The effective mechanical properties of CNT-based composites were evaluated using a 3-D cylindrical representative volume element (RVE). Continuum mechanics model was used for estimating the effective Young's modulus in the axial direction of the RVE. The load transfer conditions between carbon nanotubes and matrix were modeled using a separated interfacial region. Numerical examples using FEM are presented which demonstrated that load carrying capacities of CNTs in a matrix were significant. With the addition of CNTs into a matrix at volume fractions of only about 2% and 5%, the stiffness of the composite was increase as high as 0.7 and 9.7 times for short and long CNTs, respectively. Also the effect of CNT addition to polyethylene matrix was studied. These simulation was performed using ABAQUS software and the obtained results were consistent with the experimental results reported in the literature.
