“…According to the structural characteristics of the braided multi-layered tube, the through-thickness conductivity k r is mainly affected by the interface properties of multi-phase composites. [26][27][28] The change of the braiding angle in the radial direction has no effect on the properties of the interface. Therefore, the thermal conductivity in the radial direction was considered a constant in this study.…”

Braided tubular composites have been widely applied in various industries, such as aerospace, automobile, and sports, due to their light weight, high fatigue resistance, and good corrosion resistance. It is necessary to study the effect of the preform parameters on the thermodynamic behavior of braided tubular composites. A thermoelastic model of braided multi-layered tubes was developed to investigate the effect of changing the braiding angle on the thermal stress distribution. The thermal stress distributions of different structures were analyzed based on the model. The analysis results show that the layer-by-layer braiding angle critically affects the gradient of the axial thermal stress. The change rates of the braiding angle also significantly affect the gradient of the radial thermal stress. The theoretical results were verified by finite element analysis. These results are beneficial to the optimal design of braided composite tubes subjected to thermal load.

“…Simple boundary element procedure based on the hyper singular boundary integral formulations was developed for the bi‐material composite interface under the axisymmetric steady‐state heat conduction for the non‐ideal high/low thermal conductivity imperfect interface between two dissimilar materials. [ 16 ] Aghdam et al [ 17 ] proposed a method based on unit micromechanics to evaluate the thermal conductivity of the interface of unidirectional multiphase composite materials, and explored the influence of the material, structure and thickness of the interface layer on the thermal conductivity. Abovementioned models can be used to analyze the heat transfer mechanism of the bi‐material composites, however, they are too complex to apply for engineering thermal response computation.…”

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.

“…12 Yan et al 13 proposed a variational method considering the interface thermal contact resistance, which was based on the intrinsic function expansion of microscopic crystal cells to deal with the steady-state thermal conductivity problem of the fiber reinforced composite materials. The simplified unit cell micro-mechanical method 14 was used to investigate the influence of the fiber/matrix interface on the effective thermal conductivity of the unidirectional fiber reinforced polymer composites. At the same time, periodic representative volume elements model (RVE) 15 that considers both fiber/matrix interfaces and internal defects was also developed for simulating and predicting the thermal response of plain-woven composites.…”

Carbon fiber reinforced polymer (CFRP) exhibits different heat transfer phenomena along the fiber direction and the transverse direction during the heat transfer process due to its anisotropic thermo‐physical properties, which makes it difficult to quantitatively analyze the overall thermal performance of CFRP with different ply angles. A thermal resistance network model of composite material considering fiber ply angle and heat transfer direction was developed based on the series–parallel resistance computing method, and it was applied to describe the test results measured by the thermal response tests of unidirectional carbon fiber laminates. Thermal resistance Rx along the heat transfer direction and Ry transverse to the heat transfer direction calculated by the proposed model, which are related with the thermal response of the specimen, can be utilized to reflect the temperature values and temperature distribution maps. It was found that as the fiber ply angle θ increases from 0° to 45°, thermal resistance in the x‐axis direction increases from about 0.13 K/W to 2.56 K/W, while thermal resistance in the y‐axis direction decreases about 48.7%. As a result, major axis of quasi‐ellipse temperature profile changes by about +45° relative to the x‐axis.Highlights A CFRP thermal resistance network model considering ply angle was proposed. The series–parallel thermal resistance method is used to calculate Rx and Ry. The ply angle from 0° to 45°, Rx increases several times and Ry decreases by half. Major axis of elliptic temperature curve changes by +45° relative to the x‐axis.
