This method significantly enhances the toughness and tensile strength of the composites, reaching 208.7 MPa. Tribological tests show that CNT with high specific surface area and typical graphitic structures enhance the tribological performance of composites. Compared to PHT/CF composites, PHT/CNT@CF composites were given an average friction coefficient that decreased to 0.15.

It is widely used in various fields owing to its high efficiency. To investigate the effect of the nanoparticles on the fibers, online high‐speed camera observations were used to capture the dynamics of the liquid jets (liquid jets online and fibers when deposited on the mesh curtain) in the nozzle exit region after the addition of nanoparticles. Because the initiation and propagation of a liquid jet are three‐dimensional processes, two orthogonal planes that can provide a large amount of information regarding the motion of fiber particles were selected for observation in this study. The results indicated that the difference between the liquid‐jet diameters observed in the two planes was approximately within 20 μm. The nanoparticles accelerate the decay of the liquid‐jet diameter to different extents. Moreover, it increases the probability of defects such as shots. Additionally, we studied the effects of different nanoparticle sizes and concentrations on liquid‐jet dynamics. A new explanation for shot formation was proposed. The findings of this study provide valuable insights into the three‐phase flow in the field of spinning and a solid experimental foundation for the development of composite fibers.

After being toughened by polycaprolactone diol (PCL), the resulting epoxy sample (PCL‐CE) exhibited excellent toughness but poor hygrothermal aging resistance, with a tensile strength of 39.8 MPa and elongation at break of 16.9%. After being toughened by poly(tetramethylene ether glycol) (PTMG), the resulting epoxy sample (PTMG‐CE) showed good hygrothermal aging resistance but limited toughness, with a tensile strength of 33.9 MPa and elongation at break of 8.2%. Another epoxy sample (COFA‐CE) was prepared by introducing hydrophobic castor oil fatty acid (COFA) into CE, which combined the high toughness of PCL‐CE and the hygrothermal aging resistance of PTMG‐CE, reaching a tensile strength of 47.8 MPa and elongation at break of 12.9%. After 72 h of hygrothermal aging at 50°C and 100% RH, COFA‐CE retained 46.9% and 88.8% of its original tensile strength and storage modulus, respectively.

The NG/PCL started the phase transition from liquid to solid after 8 min at about 55°C in the wellbore section, and the phase transition was completed for only 2.5 min at a constant temperature of 65°C in fracture. Moreover, due to the high thermal conductivity and heterogeneous nucleation of the NG powder, the maximum strength of self‐generated proppant in the NG‐containing system can reach about 56.2 N during its growth process, which is 34.4% higher than that of pure SDB. The yield of the well‐dispersed spherical self‐generated proppants NG/SDB under the completely static condition can reach about 80%, of which the proppants with a particle size of 0.4 ~ 0.7 mm account for about 80%.
