“…For example, Zhang et al 13 applied air plasma for GF modification, and the bond force between fibers and laminated veneer lumber was increased by 66.17%. Radjef et al 14 treated carbon fibers with RF excited air plasma in a vacuum environment. IFSS results showed an improvement of 294% after air plasma treatment.…”

In this study, cold atmospheric pressure plasma jet was adopted to glass fibers surface modification with tetraethyl orthosilicate as a precursor. To enhance the interfacial bonding forces of glass fiber reinforced polypropylene (GFRP) composites, SiOx nanoparticles were polymerized on the fiber surfaces. The effect of two factors (the distance between nozzle and fiber (D) and the treatment time (T)) on the interfacial bonding behavior of GFRP composites was studied. The modified fibers and composites properties, including surface topography, chemical composition, wettability and interfacial mechanical properties, were studied comprehensively. The optimal parameters were obtained at D = 17 mm and T = 12 s. Our results indicated that the interlaminar shear strength of GFRP composites was increased by 30.79% compared to control group. Further studies found that plasma treatment introduced larger surface roughness, surface energy and more oxygen-containing functional groups, which was responsible for the interlaminar shear strength improvement.

“…This was due to the difficulty in treating the CF structure. [ 6 ] Plasma treatment (O 2 ) with carbon fiber structure improved tensile strength at 80 W and better interfacial shear strength at 20 W. [ 18 ] Recycled carbon fibers are used in automotive and aerospace applications due to their reduced environmental impact, lesser energy and fuel consumption. Carbon based reinforcements such as carbon black and carbon nano tube had lesser mechanical strength compared to carbon fiber‐based PE composites.…”

The potential advantage of plasma treated polyethylene (PEP) in mechanical properties was studied in this research. Recycled carbon fiber (CF) was the filler used for this hand layup technique. During fabrication, 4–14 wt% CF was incorporated into PEP and the results showed the impact of both filler and plasma treatment in enhancing the mechanical strength of polymer composites. Tensile results improved from 17.51 to 22.51 MPa in the polyethylene (PE) matrix. Scanning electron microscope (SEM) results showed untreated PE composites with fiber and matrix breakages as also voids reducing the compatibility of the PE/CF phases. The maximum flexural property of 25.5 MPa was observed in 10 wt% CF/PE treated with plasma. This combination was tried with different fabrication conditions in a temperature range of 180–220°C and time duration of 20–30 min. It was clearly seen that CF/PE combinations at a temperature of 180°C and time duration of 20 min had maximum tensile and flexural strength. The optimization using Taguchi method proved the significance of CF content in enhancing the mechanical properties. It also observed better tensile strength, flexural strength properties with 10 wt% CF, 180°C temperature, 20 min time from the results. Surface images of this condition showed more dispersed CF in the PE than other combinations due to optimum temperature and time duration during fabrication.

(1) Background: The paper addresses the effect of carbon fibers (CFs) treatment by low-temperature plasma with runaway electrons on the deformation behavior of the polyetheretherketone (PEEK)-layered composites. (2) Methods: The effect of the interlayer adhesion on the mechanical response of the composites was assessed through the tensile and three-point bending tests. In addition, computer simulations of the three-point bending were carried out with the use of the finite element analysis (FEM) with varying conditions at the “PEEK–CF layers” interface. (3) Results: DRE–plasma treatment during the optimal time of t = 15 min led to formation of a rougher surface and partial desizing of a finishing agent. The shear strength of the layered composites increased by 54%, while the tensile strength and the flexural modulus (at three-point bending) increased by 16% (up to 893 MPa) and by 10% (up to 93 GPa), respectively. (4) Conclusions: The results of the numerical experiments showed that the increase in the stiffness, on the one hand, gave rise to enlarging the flexural modulus; on the other hand, a nonlinear decrease in the strength may occur. For this reason, the intention to maximize the level of the interlayer stiffness can result in lowering the fracture toughness, for example, at manufacturing high-strength composites.
