“…Without tools designed to withstand the damage CFRTP can cause, tool life can be very short when machining CFRTP composites. These challenges attracted many researchers into building trusted models that can accurately predict fatigue failure of the composite and achieve an ideal machining process [117,155,162].…”

Carbon fiber-reinforced polymers are considered a promising composite for many industrial applications including in the automation, renewable energy, and aerospace industries. They exhibit exceptional properties such as a high strength-to-weight ratio and high wear resistance and stiffness, which give them an advantage over other conventional materials such as metals. Various polymers can be used as matrices such as thermosetting, thermoplastic, and elastomers polymers. This comprehensive review focuses on carbon fiber-reinforced thermoplastic polymers due to the advantages of thermoplastic compared to thermosetting and elastomer polymers. These advantages include recyclability, ease of processability, flexibility, and shorter production time. The related properties such as strength, modulus, thermal conductivity, and stability, as well as electrical conductivity, are discussed in depth. Additionally, the modification techniques of the surface of carbon fiber, including the chemical and physical methods, are thoroughly explored. Overall, this review represents and summarizes the future prospective and research developments carried out on carbon fiber-reinforced thermoplastic polymers.

“…The results exposed that the glass fiber with 0° direction has the highest fatigue life strength for all the testing conditions, and the failure has occurred due to microcracks generation, debonding, and voids at the fiber ends. Bondy et al [14] studied the influence of the direction of the fiber on the fatigue life of nylon 6,6 reinforced with 40 percent long carbon fiber directed at three different flow angles (0°, 45°, and 90°). The results showed that the rise in the fiber flow angle affected a decrease in the degree of fatigue stress.…”

The present work deals with the fatigue behavior of hybrid nanocomposites consisting epoxy strengthen by unidirectional carbon fibres, and/or woven roving glass fiber and TiO 2 nanofillers. For this purpose, nanocomposite material was manufactured by mixing TiO 2 nanoparticles with the epoxy using an ultrasonic mixer to insure complete dispersion of such particles in the base material. Different particle concentrations (1, 3, and 5) % wt. of TiO 2 nanoparticles have been added to the epoxy. Different types of hybrid nano composite materials were manufactured by adding three layers of carbon fibers and/or woven roving glass fiber to the prepared epoxy nanocomposite materials with a constant weight fraction of 30%. The laminated hybrid nanocomposite materials were then prepared using hand lay-up technique using a vacuum device. For experimental purposes tensile and fatigue test specimens have been manufactured according to ASTM-D3039 and ASTM D 3479/D 3479M-96, respectively, while ANSYS19 program was used to analyze the fatigue behavior of such materials numerically. Tensile tests were carried out at room temperature while fatigue tests has been carried out at constant stress ratio (R=-1). Scanning electron microscope (SEM) was used to identify the underlying mechanisms for fatigue failure and the progressive of damage growth. For each test, three specimens were tested and the average magnitude for each property was taken. The results obtained indicated that the hybrid nanocomposite (EP+C/C/C+3% TiO 2 ) has the highest fatigue limit and tensile strength in comparison with the other tested material, while the SEM results showed that the composite failed by a brittle way. It has been also generally observed that the addition of (TiO 2 ) nanoparticles has a positive effect on the fatigue behaviour of the such materials.

“…The direct-long-fiber-reinforced thermoplastic (D-LFT) is a composite material composed of discontinuous CFs and a thermoplastic polymer matrix with a length-to-diameter aspect ratio greater than the critical aspect ratio, providing an effective way to increase the aspect ratio of discontinuous fillers. − The tensile strength is lower than that of a similar composite containing continuous reinforcing fibers, but the resulting composites have a significant advantage over other CFRPs. For example, mass production systems are available and have been used in a variety of industries for many years.…”

The effect of the surface roughness of carbon fibers (CFs) on interfacial adhesion was investigated by comparing polyamide(PA)6-based composites using a commercial CF (T700) and a low-cost textile polyacrylonitrile-based CF (TexCF). The tensile strength of T700CFs was 66% higher than that of TexCFs; however, the Izod impact, interlaminar shear, and flexural strength of the long-fiber-reinforced thermoplastic (LFT) composites fabricated using the two CFs were significantly similar. The TexCFs with a rougher surface had a higher wettability than that of T700CFs, resulting in a higher interfacial shear strength value of TexCF/PA6 composites despite the much lower tensile strength of TexCFs than that of T700CFs. This suggests that the high surface roughness of CFs plays a critical role in strengthening the interfacial adhesion between the CFs and the matrix. It is concluded that low-cost CFs with high roughness are promising reinforcement candidates for the fabrication of adequate LFT composites despite their low tensile strength.
