A thermal conductivity computation model for carbon fiber reinforced polymer/aramid fiber reinforced polymer bi‐material composites was proposed, where thermal resistances of the fibers and matrix were regarded as the electrical resistances in circuit, and was validated by thermal response test with relative error less than 7.5%. After effect of thickness of the aramid fiber layer and that of heating temperature were discussed, it was applied to analyze the thermal response under the deep‐sea oil‐lifting condition. It was found that: (1) specimen with more than two layers (>0.56 mm) of aramid fibers shows better thermal insulation; (2) the higher the heating temperature is, the better the thermal insulation effect is, especially for specimens with multi‐layer aramid fibers.

“…Figure 8a exhibits the thermal conductivity of the composites filled with different fractions of CBH in the testing temperature range of 25-70 C. 48,49 It is clearly observed that the thermal conductivity of the composites increases gradually with increasing CBH loading content. When the content of CBH is 3 wt%, the thermal conductivity of the composite (0.31 W m À1 K À1 ) is improved by 121.43% compared with that of EP matrix (0.14 W m À1 K À1 ).…”

In order to meet the ever‐increasing demands of complex engineering applications, it is necessary to design the polymer‐based composites with the synergistic improvements in strength and toughness. Herein, the novel carbon nanotubes (CNT)‐bismaleimide (BMI) hybrid construction (CBH) was prepared through mechanical blending and pulverizing. The as‐prepared CBH with a stable structure and well‐regulated morphological construction was employed as a special functional filler to endow the epoxy‐based composites with a significantly enhanced overall mechanical property. Due to CBH can provide a multiscaled interfacial interaction with matrix, the composite loaded with 1 wt% CBH exhibited the synchronously improved both tensile modulus (1.31 GPa) and toughness (1.89 MJ m−3), which are 27.18% and 209.83% higher than those of pure epoxy, respectively. Moreover, good interfacial compatibility between CBH and matrix allows the composite loaded with 1 wt% CBH to exhibit the thermal conductivity of 0.18 W m−1 K−1, which was 28.57% higher than pure epoxy (0.14 W m−1 K−1). Be different from many other CNTs‐loaded counterparts, the aligned‐CNTs loaded composite showed a well‐maintained insulating feature. The novel carbon nanotubes‐polymer hybrid construction expands the application range of epoxy‐based insulating composites by optimizing their mechanical and thermal properties.

“…Typically, thermally conductive polymer-based composites are fabricated by dispersing high-thermal-conductive fillers, including carbon-based fillers, metals, and inorganic particles, into the polymer matrix. Carbon-based fillers include graphite, carbon fibers, graphene, and carbon nanotubes (CNTs), each of which shows high TC and excellent mechanical performance. − Particularly, graphite has excellent thermal and electrical conductivities, a high self-lubrication ability, resistance to both high and low temperatures, good corrosion resistance, and good chemical stability. Additionally, expanded graphite (EG) can be synthesized easily and affordably by reacting natural flake graphite with an interlaminar agent and then expanding the graphite sheets at a high temperature; this increases the specific surface area of the graphite sheets while retaining the above-mentioned advantageous properties of graphite.…”

Epoxy resin is extensively applied in the electronics and electrical fields because of its outstanding comprehensive performance. However, the low thermal conductivity (TC) limits its application in thermal interface materials. In the present work, epoxy-based hybrid composites with high TC were prepared by using expanded graphite (EG) and copper (Cu) nanoparticles as thermally conductive hybrid fillers via hot blending and compression-curing processes. Additionally, the influence of the Cu content on the thermal properties, mechanical properties, and morphology of each epoxy/EG/Cu composite was investigated. According to the results, the epoxy/EG/Cu composite showed a maximum TC of 9.74 W/(m·K) at a fixed EG content of 60 wt % owing to the addition of 10 wt % Cu. After the addition of 10 wt % Cu, the flexural strength, flexural modulus, and impact strengths of epoxy/EG/Cu composites were improved from 27.9 MPa, 9.72 GPa, and 0.81 kJ/m2 to 37.5 MPa, 10.88 GPa, and 0.91 kJ/m2, respectively. Hence, this study offers a feasible strategy for the design of epoxy hybrid composites with excellent TC that can be applied to thermal interface materials.
