“…The reason is attributed to the fact that the increasing content of MWCNT on carbon fiber surface could consume energy, which makes the tensile strength of composites increased 26 . In addition, MWCNT can also improve the interface load transfer of fiber‐matrix and change the crack propagation direction during tensile experiments 27 . In Figure 7b, the tensile strengths of CFR, CFR‐1, CFR‐2, and CFR‐3 are 333, 380, 459, and 324 MPa, which shows the same trend with the load–displacement curves of composites.…”

Multi‐walled carbon nanotubes (MWCNT)/carbon fiber fabric multiscale hybrid materials were prepared by grafting MWCNT on carbon fabric surface via heating grafted method to improve the mechanical and tribological properties of phenolic resin composites. Field emission scanning electron microscopy, Raman spectrometer, and X‐ray photoelectron spectroscopy were used to analyze the surface properties of carbon fiber. The results shown that the tensile strength of composites modified by 0.15 wt% MWCNT was 38% higher than that of unmodified composites. The wear rates decreased from 3.31 × 10−14 m3 (N·m)−1 for unmodified composites to 0.68 × 10−14 m3 (N·m)−1 for 0.15 wt% MWCNT reinforced composites. The reason was that the uniformly distributed MWCNT could increase interface interaction and mechanical interlocking between carbon fiber fabric and resin matrix.

“…As shown in Table , the bond strengths of the specimens with the deposited CNTs were increased by 117.94, 167.32, 186.68, and 192% compared with the specimens without CNTs. When the specimens were subjected to shearing forces, the deposited CNTs transmitted stress well, and a portion of energy was consumed due to friction between the CNTs …”

The interfacial performance between metals and resins significantly affects the mechanical properties of fiber–metal laminates. In this study, CNTs were deposited on a titanium surface via electrophoretic deposition (EPD) to improve the interfacial performance of Ti/carbon fiber-reinforced polymer composite laminates. Before EPD, the titanium plates were treated by either sandblasting, anodizing, or sandblasting/anodizing. A macroscopically rough surface and an oxide layer were formed by sandblasting and anodizing, then CNTs were deposited, and a porous layer was obtained, which improved the wettability and bonding strength. Finally, the static mechanical properties (single-lap properties, bending properties, and interlaminar shear properties) and dynamic mechanical properties (impact resistance) of the laminates were systematically explored. The introduction of CNTs played an important role in dispersing and carrying loads and providing a strong crack propagation resistance, which improved the laminates’ static mechanical properties and reduced the delamination damage under dynamic impact. Compared with the original composite laminates, the bond strength, bending strength, and interlaminar shear strength of the laminates deposited with CNTs after sandblasting were increased by 117.94, 46.85, and 145.61%, respectively. When the impact energy was 35 J, the damage area of the composite laminate deposited with CNTs was decreased by 27.75%.

“…It has been reported that the PUF microparticles can obstruct the propagation of cracks, alternate the crack propagation's course, and raise the cracking region through absorbing harmful energy. [ 26 ] The fracture models of the hybrid composites with diverse interface bonding strengths are shown in Figure 4(A). [ 27 ] The strong interfacial bonding with the brittle phase leads to failure performance of CF/epoxy resin composites, while the propagation of crack can be delayed after applying the microparticles.…”

In the present study, we introduce an innovative procedure to manufacture engineered hybrid composite composed of epoxy resin as the polymeric matrix, carbon fibers, and poly urea-formaldehyde (PUF) microparticles. An ultrasonic probe was utilized to achieve a uniform molecular combination of the epoxy resin and PUF microparticles. Emulsion polymerization was also used in this research to synthesize micro-polyurea formaldehyde powders. Fourier transform infrared spectroscopy, thermogravimetric analysis (TGA), tensile, and three-point bending assessments were implemented on unfilled, 2, 5, 10, and 13 wt% PUF microparticles filled epoxy resin to identify the loading influence on the diffusion rate, as well as the mechanical and thermal performance of the hybrid composite structure. The results of the flexural test show that both strength and modulus increased with a growing loading proportion of PUF microparticles. Moreover, optimum properties were achieved by adding 10 wt% microparticles. The results of the TGA demonstrate that the thermal behavior of the composite structure is sensitive to the PUF microparticles content. Based on the experimental data, the tensile test has also shown optimum behavioral properties through increasing the level of micro-particles in the sample E-40, which is due to the appropriate, uniform, and advanced composition of particles, matrices, and fibers. In addition, we used Fick's Law to determine the gas diffusion and mass transfer rates for samples at different temperatures. The gas absorption test revealed that the enhanced hybrid system behavior can be an obstacle to water and moisture.
