“…However, these scattering processes are predominantly dominant at different temperature ranges. Using a calorimetric method, we found that values on thermal diffusivity and thermal conductivity measured in-plane to the fiber axis decreased with respect to those obtained out-plane of laminate [24,25]. There is not a significant difference in thermal diffusivity values in warp and weft directions because the fiber counts in the warp and weft directions are equivalent without any porosity in either direction.…”

Heat transfer within carbon fiber in the geopolymer composite is predicted from parallel in phase to a perpendicular direction within the fabrics. Temperature distribution is higher along the fiber axis with a perpendicular position. The use of curvilinear coordinates along the fiber axis are useful in estimating thermal conductivity within the geopolymer composite theoretically. Experimental findings are also carried out in carbon fiber reinforced geopolymer composite. It has been observed that thermal conductivity has remained constant throughout the composite as a function of temperature. A correlation has been established that shows the heat transfer in the composite falls within the standard range of the specification of insulating materials. This study offers insights and a possible strategy for the development of an anisotropic low-thermal-conductivity geopolymer composite for potential applications in insulating material systems.

“…ε of the electrothermal film (4 cm × 4 cm) was 66.7% at 10 V, which is higher than that of traditional electrothermal materials. ,− When the input voltage increases continuously, the heat response speed of the electrothermal film remains stable. Figure a describes the functional relationship between the operating temperature and the power density of the electrothermal film.…”

With the development of flexible electronic technology, there is a growing demand for electrothermal materials that are environmentally friendly, safe, low-cost, and large-scale producible for efficiently solving thermal management issues. In this study, low-cost water-based carbon series electrothermal ink is prepared by a dispersion and grinding method, and the electrothermal films with various areas can be prepared on a large scale by screen printing. Simultaneously, the three-dimensional (3D) conductive network structure of graphene nanosheets (GNSs)/multiwalled carbon nanotubes (MWCNTs)/carbon black (CB) is built by the ball milling dispersion process. Due to the low percolation threshold network formed by GNSs/CNTs/CB, the prepared ink has excellent conductivity, and the square resistance (R sq ) reaches 4.3 Ω sq −1 with a thickness of 25 μm. Moreover, the saturation temperature (T s ) of the screen-printed electrothermal film (4 cm × 4 cm) can reach 165 °C with an input voltage of 10 V, and it has extremely low power consumption (444.75 cm 2 W −1 ). The electrothermal film also maintains relatively stable electrical properties in a bending test of 115 000 cycles. When the heating device (9 cm × 31 cm) is applied to the expanded polypropylene (EPP) box, the food temperature can be kept around 60 °C and the flavor can be well preserved.

“…The studied material from technical textiles with a mass density of 60 kg.m À3 consisted of several layers combined by felting. 55,56 Due to the fact that the examined material consists of synthetic combustible materials, it can be classified in the fire reaction class E according to the test protocol according to EN 13501-1+A1. 57 To achieve the required fire safety, the products are modified with chemical substances that prevent not only flare-ups or ignition but also the spread of flames at various stages of the burning process.…”

The paper deals with the fire technical characteristics of insulation panels made of recycled technical textiles from the automotive industry. The introductory part focuse an of the use of recycled textiles, a description and division of technical textiles, a description of the examined material and its composition, combustion processes, and the method of handling waste textiles. The monitored characteristics were the determination of the ignitability of the material, the gross calorific value as well as the radiant heat resistance. The measurements were carried out on samples from recycled technical textiles before and after their treatment with flame retardants (Isonem Anti-fire Solution, Ecogard B45, HR Prof, woven carbon foil, non-woven carbon foil). The best results in the ignitability test after treatment with liquid flame retardants were obtained after treatment with Ecogard B45. The results show that when flame retardants are used, the released heat during the combustion of the monitored materials treated through the dipping method is significantly lower from 13.7 MJ/kg to 23.7 MJ/kg. The lowest gross calorific values were achieved when using liquid flame retardant HR Prof when applied by dipping. The proportion of material that did not burn was very low (4.61 to 5.63%). After exposure to radiant heat for 10 min, the highest mass loss was 13.6% (dipping in Ecogard B45) and the smallest 1.8% (non-woven carbon foil). Based on results, it shows that flame retardant ECOGARD® B45 for the insulation material Senizol AT XX2 TL60 made from recycled technical textiles is the most suitable fire protection.
