Zhi 5 of these structures would be observed if the fillers have a large contact surface and aspect ratio, see examples in the previous studies, carbon fiber [10,21], CNTs [17,22] and graphene [19,23]. For example, in work [22] a wide review of works aimed at studying the relationship between the geometric shape of the filler and the structure of the polymer composites was presented.…”

“…Currently, various types of fillers haven been attempted to improve these characteristics of conductive polymer composites (CPCs). The most popular fillers are carbon-based materials, i.e., carbon fibers [10][11][12], carbon black [13][14][15], carbon nanotubes (CNT) [16][17][18] and graphene [19,20]. These materials have a number of distinctive characteristics, such as good processability, low cost, low density (especially in comparison to metal fillers), high rates of mechanical, electrical and thermal properties, stability, and comparative unpretentiousness to storage conditions.…”

Spatial Confining Forced Network Assembly (SCFNA) method is an effective method for the enhancement of electrical conductivity. In the current paper, a composite material consisting of polydimexilsiloxane (PDMS) and short carbon fiber (SCF) was modified by adding graphene nanoplateletes (Gr) at a concentration of 1~4 wt% into the composite system. The electrical properties of the obtained samples were compared with those prepared by compression molding to evaluate the effectiveness of SCFNA. The results showed that the addition of graphene increased the electrical conductivity of the composites by more than 4 orders of magnitude. Meanwhile, a polymer-based three-phase composite with the highest electrical conductivity of 287 S/m was obtained utilizing the SCFNA method in the present work.

“…Therefore, such materials have been applied to a wide range of fields, ranging from the civil/military aviation space industry to the automobile industry, as well as in sports, where lightweight materials are essential [7,8,9,10,11,12]. However, thermoplastic resins with low thermal conductivity limit the commercialization of the CFRP as a polymer matrix for composites [13,14]. Composites with low thermal conductivity do not dissipate heat quickly but accumulate heat, which causes deterioration of the mechanical properties due to peeling between the carbon fiber and the polymer matrix of the composite.…”

Improving the Vertical Thermal Conductivity of Carbon Fiber-Reinforced Epoxy Composites by Forming Layer-by-Layer Contact of Inorganic Crystals

A carbon fiber-reinforced polymer (CFRP) is a light and rigid composite applicable in various fields, such as in aviation and automobile industry. However, due to its low thermal conductivity, it does not dissipate heat sufficiently and thus accumulates heat stress. Here, we reported a facile and effective strategy to improve the through-thickness thermal conductivity of CFRP composites by using a layer-by-layer coating of inorganic crystals. They could provide efficient heat transfer pathways through layer-by-layer contact within the resulting composite material. The high thermally conductive CFRP composites were prepared by employing three types of inorganic crystal fillers composed of aluminum, magnesium, and copper on prepreg through the layer-by-layer coating process. The vertical thermal conductivity of pure CFRP was increased by up to 87% on using magnesium filler at a very low content of 0.01 wt %. It was also confirmed that the higher the thermal conductivity enhancement was, the better were the mechanical properties. Thus, we could demonstrate that the layer-by-layer inclusion of inorganic crystals can lead to improved through-thickness thermal conductivity and mechanical properties of composites, which might find applications in varied industrial fields.

“…Defects resulting from the manufacturing processes, such as cracks and holes, can cause electric potential and temperature discontinuities across the defects boundary and stress concentrations, then result in fracture [7][8][9][10][11][12][13]. Fracture problems in thermoelectric materials have been received much attention and investigated by many experts recently, like other structural materials subjected heat loadings problems [14][15][16]. The slow Vickers indentation crack growth behavior of Mg 2 Si thermoelectric material was observed by Schmidt et al [17].…”

The two-dimensional problems of an elliptic hole or a rigid inclusion embedded in a thermoelectric material subjected to uniform electric current density and energy flux at infinity are studied based on the complex variable method of Muskhelishvili and conformal mapping technique. The closed-form solutions of electric potential, temperature and stress components are presented according to electrical insulated and thermal exact boundary conditions on the rim of the hole or inclusion. Numerical results are carried out to illustrate the influence of the value of major to minor axis ratio of the elliptic geometry and heat conductivity of inhomogeneity on thermoelectric and stress fields. It is found that energy flux at surfaces of the hole or rigid inclusion does not vanish due to the Joule heat and Seebeck effect when the electric field is applied. In addition, stress induced by applied electric field has a non-linear relationship with the electric current density. The heat conductivity of the air inside the elliptic hole reduces the concentration factors of energy flux and stress. However, the concentration factors of energy flux and stress at the bonding interface increase with the increasing values of heat conductivity of the flat rigid inclusion.
