“…Moreover, sample s D5 and D6 shows a noticeable reduction in the thermal conductivity and this might be due to a high-volume fraction of particles or more loading of small particle size of Alumina in composite results in increased particle aggregations which lead to an important increase in interfacial thermal resistance and unacceptable thermal conductive rendering of polymer composites. as indicated in previous studies [11,27,28].…”

Hybrid polymer compounds have become modern times, as their applications have increased, especially those reinforced with fibers and molecules due to their high performance, which allows them to be used in different applications. In this research, the dependence of the thermal conductivity and density of epoxy compounds on the volume fraction ratio of the reinforcements including carbon fibers, silicon carbide and alumina will be discussed. new hybrid epoxy compounds have been developed. The epoxy compounds reinforced with plain weave carbon fibers with different volume fractions of micro-particles of silicon carbide and alumina were prepared by hand lay-up. The physical properties including thermal conductivity and density of hybrid epoxy compounds were determined experimentally. The results showed an increase in the thermal conductivity by increasing the proportion of silicon carbide and alumina without affecting the density of the epoxy compound. This high improvement in thermal conductivity with low density in these hybrid epoxy composites have been driven them as possible nominations for electronic devices. The optimum content of hybrid epoxy composite for electronic applications is at SiC 10% and Al2O3 5% with 15 carbon fiber and 70 epoxy. Thus, a new polymer-based compound with improved thermal conductivity for electronic applications was produced.

“…3k, the thermal conductivity of the previously worked polymer-based CFs composites is compared according to the classication of manufacturing processes, and more detailed data are shown in Table S2. † The lowest thermal conductivity is of the composite materials with random structures prepared by casting, 12,46,47 and their thermal conductivity is lower than 10 W m −1 K −1 . Due to the weak driving force, the composite prepared by approaches of ice template, 28,48,49 magnetic eld, 11,50,51 and electric eld 23,52,53 is not enough to align the high content of ller, so it only obtains slightly higher thermal conductivity.…”

“…In recent years, a large number of studies have demonstrated that the combined use of one-dimensional and two-dimensional thermally conductive fillers can significantly improve the thermal conductivity of composites. − For example, Han et al fabricated epoxy-based composites with improved thermal conductivity through the synergistic effect between one-dimensional silicon carbide nanowires and two-dimensional boron nitride nanosheets with a fixed content of thermally conductive filler. Similarly, Liang et al employed a mixture of one-dimensional carbon fiber (CF) and two-dimensional Al 2 O 3 with a fixed component ratio as the thermally conductive filler and improved the thermal conductivity of polydimethylsiloxane with the single thermally conductive filler from 5.89 to 7.91 W/m K. All the results prove that the synergistic effect of the “line-surface” heterogeneous structure between one-dimensional and two-dimensional thermally conductive fillers is beneficial to the construction of the heat conduction path.…”

The “solid–liquid” leakage and low thermal conductivity of organic phase change materials limit their wide range of applications. In this paper, a novel carbon fiber/boron nitride (CF/BN)-based nested structure was constructed, and then, a series of poly(ethylene glycol) (PEG)-based phase change composites (PCCs) with high thermal conductivity and mechanical strength were prepared via the simple vacuum adsorption technology by employing the CF/BN nested structure as the heat conduction path and supporting material and the in situ obtained cross-linking epoxy resin as another supporting material. The thermal conductivity of the obtained PCC is as high as 0.81 W/m K, which is 7.4 times higher than that sample without the CF/BN nested structure. The support of the double skeletons confers the obtained PCCs with excellent mechanical strength. Surprisingly, there is not any deformation for PCCs under the pressure of 128.5 times its own weight during the phase change process. In addition, the phase change enthalpy of the obtained PCC is as high as 107.9 J/g. All the results indicate that the obtained PEG-based PCCs possess huge application potential in the field of industrial waste heat recovery.
