“…Under axial compression load, the FRP tubes constrain the lateral expansion deformation of the internal concrete, resulting in three-dimensional compression, improving the strength and ductility of the confined concrete (David et al, 2019; Gudonis et al, 2013). By applying it to the compression bars of truss structure, the excellent unidirectional mechanical property of FRP profile could be better utilized, effectively solve the traditional steel corrosion problem, improve the stability and service life of the structure, and reduce the overall life cycle cost of the structure (Alsubari et al, 2021; Liu et al, 2014; Rajak et al, 2022).…”

To solve the instability of the compression bars in the space truss composed of GFRP tubes, a composite column with high-strength concrete (HSC) confined by glass fiber-reinforced plastic (GFRP) tube was proposed. High-strength self-compacting micro-expansive concrete with a slump greater than 255 mm was produced under normal-temperature curing conditions and confined by GFRP tubes. A mechanical performance test of the GFRP-confined HSC short column under axial compression was performed. The effects of GFRP tube types, concrete expansion agent, constraint effect, ultimate load capacity, and failure mode of the composite structure were discussed and analyzed through the test. A model of the stress-strain response of the GFRP confined HSC column was proposed. The results show that the 45° fiber-wound GFRP tube has a significant restraining effect on the HSC. The stress-strain relationship increases quadratically in a linear fashion. When the composite column was damaged, the GFRP fiber was broken and the concrete was crushed. The ultimate strength was about 1.5 times that of unconstrained HSC columns, and the loading method has less influence on the results. The expansion agent has a significant effect on the deformation performance of the composite column, and its ultimate strain was about 1.4 times that of the composite column without expansion agent.

“…In the aerospace and automobile industry, light materials such as carbon fiber reinforced thermoplastics are increasingly adopted to replace the traditional steel parts, [1][2][3][4] because of their excellent corrosion resistance, [5] high specific strength, [6] and high toughness [7,8] in addition to recyclability. [9,10] In order to fabricate short fiber reinforced thermoplastics (SFRT), injection molding process has usually been utilized, with the advantage of low cost and rapid fabrication of complex structural parts.…”

Injection compression molding technique with self‐resistance electric heating provides an effective way to fabricate continuous carbon fiber reinforced thermoplastics (cCFRTs) components, but it may also have a significant impact on the properties of the components by inducing undesirable effects. It is necessary to understand the manufacturing process and minimize the introduction of undesirable factors. Thus, this work is to investigate the influence of process parameters (i.e., melt temperature, current intensity, holding pressure, and holding time) on the impregnation quality and mechanical properties of cCFRTs. The results show that fiber fabrics cannot be uniformly distributed in all cCFRTs, resulting in a thick polymer layer on the top of all cCFRTs. Moreover, the fiber distribution shows insensitive to the processing parameters. The increase of melt temperature, the decrease of current intensity and the extension of holding time are conducive to reduce void content and the frequency of macro void; While excessive holding pressure cannot reduce void content due to serious overflow of resin. Meanwhile, the effect of processing parameters on the mechanical properties and fracture morphology of the sample was also determined. The findings show that the flexural strength of the sample is 106.7 ± 0.8 MPa using the optimal processing parameters.

“…The construction of mechanical interlocks between the metal and polymer has been a commonly used strategy to improve joint strength [ 13 , 14 , 15 , 16 ]. Jiao et al [ 17 ] developed a hybrid surface pre-treatment method by adding a PA layer to the CFRP-Al alloy interface and machining microtextures on the Al alloy surface to enhance the joint strength.…”

The generation of high-performance heterojunctions between high-strength resin matrix composites and metals is of great significance for lightweight applications in fields such as aerospace and automobile engineering. Herein, we explored the feasibility of employing a laser joining process to achieve high-strength heterojunctions between continuous carbon fiber-reinforced PEEK (CCF30/PEEK) composites and titanium alloy (Ti6Al4V). A joint strength of over 50 MPa was achieved through constructing mechanical interlocking structures between CCF30/PEEK and Ti6Al4V. Tensile tests revealed that the fracture of joints was mainly ascribed to the detachment of carbon fibers from the resin matrix and the breakage of carbon fibers. The structures with different orientations and dimensions were confirmed to significantly influence the formation of interlocking structures near the joining interface and the resultant fracture strength of joints. It is believed that the results presented in this study provide a strong foundation for the production of high-performance heterojunctions.
