“…In fibre-reinforced composites, the interfacial region between the fibres and the matrix determines the extent of stress transfer, and plays a critical role in the overall composite mechanical properties [182]. Due to their size, stiffness and strength, CNTs have the potential to strengthen the fibre/matrix interface when used as an auxiliary reinforcement at the fibre surface, leading to increased load-bearing capacity and fatigue resistance [181,182]. There are a variety of routes to grow or graft CNTs onto the fibre surface, but EPD is particularly straightforward, providing uniform deposits with a homogeneous microstructure, in a scalable, potentially continuous fashion.…”

“…Notably, the CNT coating process can be carried out at ambient conditions, preserving the fibre strength and modulus, in contrast to most CVD or other high-temperature processes. EPD has been applied to graft functionalised CNTs onto conductive carbon fibres (CF) as well as non-conductive glass fibres (GF) and the resulting epoxy matrix composites have shown improved interfacial shear strength, interlaminar shear strength, flexural strength and flexural modulus, when compared with composites made using commercial fibres [91,155,[181][182][183][184][185][186][187]. CNTs can be deposited on continuous fibre tows [194] or infused into woven fibre preforms ( Figure 13) [185].…”

Electrophoretic deposition (EPD) is a powerful technique to assemble carbon nanotube (CNT) coatings and composite films with controlled architectures. This comprehensive review of the EPD of CNTs and CNT-containing composites focuses on achievements within the last 15 years and ongoing challenges. Stable CNT suspensions are a prerequisite for successful EPD and have been prepared by a variety of strategies, discussed here. The resulting film microstructure is determined by the initial feedstock, the suspension, and the EPD approach applied, as well as a variety of EPD processing parameters. Nanocomposites can be prepared via co-deposition, sequential deposition, or post-deposition treatments, to introduce metallic, ceramic or polymeric phases. There are numerous potential applications for both homogeneous and patterned CNT films, including as structural reinforcements for composites, as field emission, energy storage and conversion devices, as well as in biomedical applications. The advantages and disadvantages of EPD processing in these contexts are discussed.

“…The fragment length within the gauge length was measured via image analysis with a calibrated measuring scale. The IFSS between the carbon fiber and epoxy resin was calculated using the following Equation (3) [ 19 , 20 , 21 , 22 ]:

where σ f is tensile strength of CF, D is diameter of CF, and l c is the critical fiber length. The critical fiber length ( l c ) can be determined using the average fragment length ( l ) by Equation (4):

Curing Effects on Interfacial Adhesion between Recycled Carbon Fiber and Epoxy Resin Heated by Microwave Irradiation

The interfacial adhesion of recycled carbon fiber (CF) reinforced epoxy composite heated by microwave (MW) irradiation were investigated by changing the curing state of the epoxy resin. The recycled CF was recovered from the composite, which was prepared by vacuum-assisted resin transfer molding, by thermal degradation at 500 or 600 °C. Thermogravimetric analysis showed that the heating at 600 °C caused rough damage to the CF surface, whereas recycled CF recovered at 500 °C have few defects. The interfacial shear strength (IFSS) between recycled CF and epoxy resin was measured by a single-fiber fragmentation test. The test specimen was heated by MW after mixing the epoxy resin with a curing agent or pre-curing, in order to investigate the curing effects on the matrix resin. The IFSSs of the MW-irradiated samples were significantly varied by the curing state of the epoxy resin and the surface condition of recycled CF, resulting that they were 99.5 to 131.7% of oven heated samples Furthermore, rheological measurements showed that the viscosity and shrinking behaviors of epoxy resin were affected based on the curing state of epoxy resin before MW irradiation.

“…Carbon fiber‐reinforced polymer composites have excellent properties of both carbon fibers and resins, but there are also some defects, such as low interfacial strength. In order to improve the performance of carbon fiber‐reinforced composites, a series of improvements have been made . In service life, such composites inevitably experience temperature changes and humidity changes along with the coupled effect of external loads when they are in use, resulting in the generation of damage within the structure, seriously affecting the mechanical properties of the overall structure .…”

Fiber‐reinforced polymer matrix composites (FRPMCs) are the most promising and valuable material developed in the last few decades. In response to the increased research and publications concerning the thermal stability of FRPMCs, this review has culled typical journals for publications relevant to structural stability. In this review, the effects of temperature on the structural integrity of FRPMCs are discussed from the perspective of matrix types, fiber types, nanoparticle (NP) modifications on resin matrix, and various related mechanical properties. For NP‐modified FRPMCs, characterization of all anisotropic properties under various strain rates and temperatures becomes essential for analysis, design, and numerical simulations. Improving the structural stability of FRPMCs at different temperatures is an important direction. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 48206.
