“…Zhang et al [ 88 ] used polyurethane (PU) for carbon fibre sizing before hot pressing with polycarbonate (PC) films to form CF/PC composite laminates. Four types of PU were used to size carbon fibres, namely: blocked polyisocyanate PU, PC-PU, polyester PU and blocked polyether PU.…”

The paper critically analyzed different interfacial enhancing methods used in thermoplastic composites. Although the absence of cross-linked polymer chains and chemical bonds on solidification enables the thermoplastics to be remelted, it creates weak interfacial adhesion between fibre reinforcements and the thermoplastic matrix. The weak fibre-matrix interface bonding reduces the efficiency with which the applied load can be transferred between these composite constituents, causing the composite to fail prematurely. Their need for high-temperature processing, poor compatibility with other polymer matrices, and relatively high viscosity render thermoplastics challenging when used to manufacture composite laminates. Therefore, various methods, including nanoparticles, changing the polarity of the fibre surface by plasma etching, chemical treatment with ozone, or an oxidative attack at the fibre surface, have been applied to improve the fibre/matrix bonding in thermoplastic composites. The fabrication steps followed in these techniques, their progress in research, and the associated toughening mechanisms are comprehensively discussed in this paper. The effect of different fibre-matrix interfacial enhancement methods on the mechanical properties of thermoplastic composites is also deliberated.

“…Researchers have done much work on sizing CF for reinforcing thermoplastic resins. [14][15][16][17] Karsli et al revealed that polyurethan or polyamide as sizing agent of CF for reinforcing polyamide 66 (PA66) matrix possessed higher interfacial adhesion than other sizing materials, and tensile strength of the composites was enhanced by about 18% compared with that with unsized CF. 18 Liu et al used poly(phthalazinone ether ketone) that is the same as the matrix resin to size CF and found the interfacial shear strength (IFSS) of the sized CF reinforced composite was increased by 30%.…”

The interfacial adhesion character highly depends on interactions of the interfacial molecules. Carbon fiber (CF) is sized by in situ polymerization of maleic acid and glycerol to form a hyperbranched polyester (HBPE) layer on the surface in an environmental and efficient technique. Vast hydroxyl groups are introduced to the CF surface with the presence of HBPE. Moreover, the HBPE sizing structure on 6 A/m2 moderately oxidized CF surface presents higher branch extent and more terminal hydroxyl groups than that on unoxidized or over‐oxidized CF surface. The interlaminar shear strength of polyamide 66 composite reinforced with HBPE sized oxidized‐CF under 6 A/m2 current density is optimal and remarkably enhanced to 77.9 MPa by 46% compared to that with the unsized one. The significant interfacial property improvement is attributed to the abundant terminal hydroxyl groups on HBPE sizing structure, which enhances the interaction at the interface of CF/sizing and sizing/matrix by constructing many covalent and hydrogen bonds.

“…Many approaches have been adopted to enhance the interfacial interaction between PI fibers and resin matrix, including plasma, 10 chemical crosslinking, 11 alkali treatment, 12 radiation 13 and sizing treatment 14–15 . For instance, Dang et al 16 functionalized the alkali‐treated PI fibers surface with cellulose nanocrystals under the combined catalytic action of a Lewis acid and a crosslinker, improving the oxygen‐containing polar groups and the surface roughness of the PI fibers.…”

To improve the interface adhesion between high‐strength‐high‐modulus polyimide (PI) fibers and epoxy resin (EP) matrix, waterborne epoxy resin (WEP) sizing agents are used to modify the surface of PI fibers. The sizing treatment of PI fibers was carried out by the self‐made sizing machine, and the effect of WEP sizing concentrations on the structure and properties of PI fibers were discussed in detail. The surface roughness, activated carbon percentage, and surface energy of WEP‐sized PI fibers increased with increasing WEP sizing agent contents. While, the mechanical and thermal properties of WEP‐sized PI fibers decreased slightly with the increment of WEP sizing agent concentrations. The optimum WEP sizing concentration was recognized to be 2 wt%. The interfacial shear strength and the interlinear shear strength values of PI fibers and epoxy resin (PI/EP) composites were improved by 175.22 and 25.31%, respectively. Moreover, the mechanism of surface characteristic improvement with WEP sizing treatment were proposed, contributing to the enhancement of mechanical interlocking and chemical interaction between fibers and matrix.
