“…The wettability of the CFs can be reflected by the contact angle. For a specified test liquid, the smaller the contact angle, the easier it is for the droplets to spread on the CF surface and the better the wettability with the CFs 30 . The carbon‐fluorine bond has immense bond energy.…”

To improve the interfacial bonding effect of carbon fibers (CFs) and epoxy resins, we prepared a fluorine‐containing high‐epoxy‐value sizing agent (named TS) in this article. It is an emulsion with a more uniform particle size distribution and higher stability better than a commercial Takemoto sizing agent. In addition, sulfonic acid groups can improve the hydrophilicity of the TS, and the presence of epoxy groups enhances the wettability between CFs and the matrix. The properties of the sizing agents were examined by Fourier transform infrared spectroscopy, dynamic light scattering, and thermogravimetric analysis. The sized CFs were evaluated by scanning electron microscopy, x‐ray photoelectron spectroscopy, monofilament tensile test, and dynamic contact angle. Afterward, CF/epoxy composites were prepared, and their fracture morphology and interlaminar shear strength (ILSS) were examined. Results indicated that the TS sizing significantly increased the content of activated carbon on the surface of the CFs and improved the bonding effect between the fiber and the matrix. After TS was sized, the ILSS increased from 49.64 to 58.74 MPa, 18.34% higher than unsized CF/epoxy composites, showing the prominent interfacial reinforcement better than commercial Takemoto.

“…Dhakal and Sain [188] observed an increase in tensile strength and modulus to 517.7 MPa and 18.9 GPa, respectively, for flax/carbon hybrid between 68.1 MPa and 4.7 GPa, respectively, for flax fibre reinforced composites. Similarly, carbon/flax/flax/carbon fibre hybrid composites exhibited higher tensile strength and modulus, flexural strength and modulus, and impact strength of 128.5 MPa, 2.1 GPa, 387.7 MPa, 35.8 GPa, and 13.7 kJ/m 2 , respectively, compared with 88.7 MPa, 1.2 GPa, 170.9 MPa, 14.2 GPa, and 27.7 kJ/m 2 for basalt/flax/flax/basalt fibre hybrid composites [189].…”

The global drive towards a circular economy that emphasizes sustainability in production processes has increased the use of agro-based raw materials like natural fibres in applications that have long been dependent on inorganic raw materials. Natural fibres provide an eco-friendly, more sustainable, and low cost alternative to synthetic fibres that have been used for a long time in the development of composite materials. However, natural fibres are associated with high water absorption capacity due to their hydrophilic nature leading to poor compatibility with hydrophobic polymeric matrices, thus lower mechanical properties for various applications. Hybridization of natural fibres with synthetic fibres enhances the mechanical performance of natural fibres for structural and nonstructural applications such as automobile, aerospace, marine, sporting, and defense. There have been increased research interests towards natural/synthetic fibre hybrid composites in the past two decades (2001–2021) to overcome the identified limitations of natural fibres. Therefore, understanding the parameters affecting the properties and potential of using natural and synthetic fibre reinforcements to develop hybrid composites is of great interest. The review showed that using appropriate fibre orientation, fibre weight fraction and stacking sequence yields good mechanical, physical, and thermal properties that are competitive with what only synthetic fibre reinforced composites can achieve. In addition, these properties can be improved through pretreatment of natural fibres using different chemicals. This paper provides in review form the parameters affecting the mechanical, physical, and thermal properties of natural/synthetic fibre hybrid reinforced polymer composites from the year 2001 to 2021.

“…Therefore, it is necessary to select other efficient hydrophilic monomers. Polyamide fibers are provided with excellent moisture absorption, which is owing to the macromolecular components of amide groups (excellent hydrophilicity). , Thus, the hygroscopicity of polyamide fibers exhibits a significant ascendancy to that of PET fibers, and the moisture regain of PA6 fibers is about 4.5% and that of PA56 fibers is about 5.5%. − …”

Improving the hygroscopicity of poly(ethylene terephthalate) (PET) is a desired goal, and aliphatic amides with hydrophilic groups are ideal modified monomers. In this paper, two aliphatic amides (adipate pentamethylenediamines (APs) and phosphorylacetic acid (APA)) with different segment lengths were prepared by the reactions between 1,5pentane diamine and adipic acid, which were copolymerized with purified terephthalic acid (PTA) and ethylene glycol (EG) to synthesize the copolymers PET/APs and PET/APA, respectively. The chemical structures of the modified monomers and copolymers were confirmed by Fourier transform infrared (FTIR) and NMR spectroscopy. In addition, the copolymers exhibited excellent moisture regain (MR) and water absorption capability (WAC). When the molar content of modified monomers was 12%, the MR and WAC of PET/APs increased by 200 and 420% and the MR and WAC of PET/APA increased by 218 and 475%, respectively. Moreover, PET/APA exhibited better hydrophilicity than PET/APs due to the effect of the microsequence structure. Based on the analysis of the sequence distribution and isothermal crystallization kinetics, PET/APA possessed a more random sequence distribution and larger amorphous region due to the effect of the long flexible segments of APA, promoting the diffusion of water molecules and binding to hydrophilic groups. In addition, PET/APA possessed a more qualified yellow index (b value) than that of PET/APs. Thus, it provided a synthesis technique and broad application prospects.
