“…The manufacture of lightweight materials has always been one of the goals pursued in advanced manufacturing industries such as automotive engineering and aerospace. Towards this goal, various light materials including carbon fiber- and glass fiber-reinforced thermoplastics (CFRTP/GFRTP) have been increasingly utilized to replace metals due to their low density, high specific strength and good chemical resistance [ 1 , 2 , 3 , 4 ]. In practical applications of CFRTP/GFRTP, it is inevitable to confront the issue of achieving high-strength heterojunctions between metals and thermoplastic composites.…”

The development of heterojunctions with a strong bonding interface between metals and non-metals has attracted much attention owing to their great potential for use in lightweight structures. Laser joining technology, which emerged as a fast and reliable method, has proven its feasibility and unique advantages in joining metal to polymer matrix composites. Herein, an optimized laser joining configuration has been employed to realize high-quality joining of titanium alloy and carbon fiber-reinforced composite. Cross-sectional microstructures of laser-produced joints reveal that micro-bubbles near the interface have been effectively suppressed and eliminated due to the continual clamping pressure applied to the joined area during the joining process. Tensile tests suggest that the joint strength increases with structure density on a titanium alloy surface, and the greatest fracture strength of joints reaches more than 60 MPa even after experiencing a high–low temperature alternating aging test. For higher structure density (>95%), the joints fail by the fracture of parent plastics near the joined area due to the tensile-loading-induced peel stress at the edges of the overlap region. Otherwise, the joints fail by interfacial shear fracture with breakage when the structure density is lower than 91.5%. The obtained high-performance heterojunctions show great potential in the aerospace and automotive fields.

In this study, the mechanical and thermophysical properties of carbon fiber-reinforced polyethersulfone are investigated. To enhance the interfacial interaction between carbon fibers and the polymer matrix, the surface modification of carbon fibers by thermal oxidation is conducted. By means of AFM and X-ray spectroscopy, it is determined that surface modification changes the morphology and chemical composition of carbon fibers. It is shown that surface modification dramatically increases the mechanical properties of the composites. Thus, flexural strength and the E-modulus of the composites reinforced with modified fibers reached approximately 962 MPa and 60 GPa, respectively, compared with approximately 600 MPa and 50 GPa for the composites reinforced with the initial ones. The heat deflection temperatures of the composites reinforced with the initial and modified fibers were measured. It is shown that composites reinforced with modified fibers lose their stability at temperatures of about 211 °C, which correlates with the glass transition temperature of the PES matrix. The thermal conductivity of the composites with different fiber content is investigated in two directions: in-plane and transverse to layers of carbon fibers. The obtained composites had a relatively high realization of the thermal conductive properties of carbon fibers, up to 55–60%.

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.
