The influence of nanodiamonds (NDs) on the thermal and ablative performance of carbon-fiber-reinforced–epoxy matrix compositeswas explored. The ablative response of the composites with 0.2 wt% and 0.4 wt% NDs was studied through pre-and post-burning morphologies of the composite surfaces by evaluation of temperature profiles, weight loss, and erosion rate. Composites containing 0.2 wt% NDs displayed a 10.5% rise in erosion resistance, whereas composites containing 0.4 wt% NDs exhibited a 12.6% enhancement in erosion resistance compared to neat carbon fiber–epoxy composites. A similar trend was witnessed in the thermal conductivity of composites. Incorporation of composites with 0.2 wt% and 0.4 wt% NDs brought about an increase of 37 wt% and 52 wt%, respectively. The current study is valuable for the employment of NDs in carbon fiber composite applications where improved erosion resistance is necessary.

“…This is generally related to the time required for reaching thermal equilibrium. 47 At low holding time, the target temperature is reached on the surface, but at high holding time, the core of the specimen reaches the operating temperature. 19 Figure 5 illustrates the interaction effect plot for the mean of LCM.…”

The elevated operating temperature is considered an essential factor affecting the performance of laminated composite structures. Under the intended conditions of use in aircraft engines and nacelles, carbon fiber reinforced polymers are exposed to temperatures ranging from room temperature to 120 C. The present work concentrates on the thermomechanical and mechanical properties of autoclaved woven carbon fiber/epoxy composite laminate subjected to different operating temperatures (60, 120, and 180 C) and holding times (10, 30, and 60 min). Thermomechanical results showed that the rigidity and stiffness of the epoxy resin matrix decrease with increasing temperature. However, all mechanical properties (laminate compressive modulus, laminate compressive strength, and interlaminar shear strength) decreased progressively with operating temperature. Laminate compressive strength and interlaminar shear strength were seen to decline up to 43.74% and 30.60% on the operating temperature of 180 C, respectively, compared to measured values at 60 C. This study indicates that only the compression properties were affected by the holding time, while the interaction between the operating temperature and holding time affects the laminate compressive modulus.

“…Polymer composites are widely used in aerospace, automotive, construction, electronic components, and other fields due to their excellent mechanical properties and corrosion resistance. 1 , 2 However, low thermal conductivity limits their applications; they must be modified to obtain high thermal conductivity. Therefore, the preparation of high thermal conductivity polymer composites has become an urgent problem.…”

The formation of highly thermally conductive composites with a three-dimensional (3D) oriented structure has become an important means to solve the heat dissipation problem of electronic components. In this paper, a carbon fiber (CF) felt with a 3D network structure was constructed through the airflow netting forming technology and needle punching. The carbon fiber/phenolic composites were then fabricated by CF felt and phenolic resin through vacuum impregnation and compression molding. The effects of CF felt content and porosity on the thermal conductivity of carbon fiber/phenolic composites were investigated. The enhancement of carbon skeleton content promotes the conduction of heat inside the composites, and the decrease of porosity also significantly improves the thermal conductivity of the composites. The results indicate that the composites exhibit a maximum in-plane thermal conductivity of 1.3 W/mK, which is about 650% that of pure phenolic resin, showing that the construction of 3D thermal network structure is conducive to the reinforcement of thermal conductivity of composites. The method can provide a certain theoretical basis for constructing a thermally conductive composite with a three-dimensional structure.
