“…Polyurethane-coated carbon fiber (CF) can be added to the process for producing thermoplastic polymer composites with improved thermal and mechanical properties, as well as durability, as an effective reinforcing filler and an improved cross-linking process. Electron beam irradiation (EB) can be added [ 21 ]. In the framework of the technological process [ 21 ], composites based on polyamide 6 (PA) with different HC content from 1 to 10 wt.% were made by melt compounding and compression molding and then irradiated with various doses of EB.…”

The development of reliable and effective functional materials that can be used in various technological fields and environmental conditions is one of the goals of modern nanotechnology. Heating elements’ manufacturing requires understanding the laws of heat transfer under conditions of different supply voltages, as this expands the possibilities of such materials’ application. Elastomers based on silicon-organic compounds and polyurethane modified with multi-walled carbon nanotubes (MWCNTs) were studied at various concentrations of Ni/MgO or Co-Mo/MgO and voltages (220, 250, and 300 V). It was found that an increase in voltage from 220 to 300 V leads to an initial increase in specific power on one-third followed by a subsequent decrease in a specific power when switched on again to 220 V (for −40 °C) of up to ~44%. In turn, for a polyurethane matrix, an increase in voltage to 300 V leads to an initial peak power value of ~15% and a decrease in power when switched on again by 220 V (for −40 °C) to ~36% (Ni/MgO -MWCNT). The conducted studies have shown that the use of a polyurethane matrix reduces power degradation (associated with voltage surges above 220 V) by 2.59% for Ni/MgO–based MWCNT and by 10.42% for Co-Mo/MgO. This is due to the better heat resistance of polyurethane and the structural features of the polymer and the MWCNT. The current studies allow us to take the next step in the development of functional materials for electric heating and demonstrate the safety of using heaters at a higher voltage of up to 300 V, which does not lead to their ignition, but only causes changes in electrophysical parameters.

“…1,2 In the present era, carbon fiber reinforced rubber composites (CFRC) are widely used in aerospace, military, defense, automotive, and in many other applications. 3,4 Generally, the high-temperature carbonization process is widely used for the manufacture of polyacrylonitrile (PAN)-based carbon fibers (CFs). However, at high temperatures, the polar elements on the surface of the carbon fiber are eliminated, resulting in a weaker interfacial bond between the carbon fiber and the substrate.…”

The carbon fibers were oxidized with concentrated hydrochloric acid, and subsequently modified in two steps. First, the oxidized carbon fibers were grafted with γ‐aminopropyltriethoxysilane (KH550) with the purpose of building a platform on the fiber surface, then the epoxy functionalized elastomer (ethylene‐vinyl acetate‐glycidyl methacrylate terpolymer, EVMG) was grafted on the carbon fiber surface. Chloroprene rubber/natural rubber/carbon fiber (CR/NR/CF) composites were prepared by mechanical blending process. Carbon fibers were characterized by different techniques such as X‐ray photoelectron spectroscopy (XPS), thermal gravimetric analysis (TGA), scanning electron microscopy (SEM), and dynamic mechanical analysis (DMA). The results show that EVMG can enhance the interface adhesion between fiber and rubber. It was observed that the surface of the carbon fiber is covered with a layer of the macromolecular film by EVMG, which increases the surface roughness and introduces epoxy groups. On the one hand, carbon fiber and rubber can be entangled through macromolecular chains, and on the other hand, interfacial bonding can be enhanced by chemical interactions. Furthermore, modification by EVMG impacted tensile strength of CF composite increase by 11.05%, the 300% constant tensile stress increased by 21.87%, and the wear resistance increased by 29.8%, respectively.

“…Song et al 25 improved the interfacial adhesion properties between carbon fiber (CF) and polyimide (PI) surfaces by coating biogenic PDA on the CF surface, and the results showed that the tensile strength and modulus of PDA‐CF/PI composites were significantly better than those of CF/PI composites, indicating that the introduction of PDA significantly improved the interfacial compatibility of CF and PI matrix. Bo et al 26 modified CF through dopamine oxidation self‐polymerization, and studied the effect of dopamine concentration on the properties of silicone rubber (SR)/CF@PDA composites. The results show that SR/CF@PDA‐1.5 has the best interface bonding properties.…”

The interface compatibility between the surfaces of nylon 66 (PA66) fiber and the acrylic rubber (AR) is the key factor to improve the mechanical properties of the composite materials. In this study, Lewis acid (CaCl2) was firstly used to reduce the crystallinity of PA66 fiber, and then a bioinspired polydopamine (PDA) function coating was constructed on the PA66 fiber surface to act as a bridge to introduce an epoxy‐functionalized silane layer (KH560). After that, the modified PA66 fiber was introduced in the CuSO4 coordination crosslinked AR composites to further increase the mechanical performances of AR. Results showed that Lewis acid could significantly reduce the surface crystallinity of PA66 fiber, the PDA coating has successfully coated the fiber surface. And SEM results showed, the interfacial compatibility between the fiber and rubber was obviously improved. Compared with the unmodified PA66 fiber filled AR composites, the tensile strength, modulus and hardness of the modified PA66 fiber filled AR composites were increased by 95%, 49%, and 16% respectively.
