“…Due to their high specific strength, CF‐reinforced polymer composites are gradually replacing other conventional materials in automotive, civil construction, rail, aerospace, aviation and off‐shore applications. [ 1,2 ] It is well‐known that CFs are used as reinforcements in composites, provided the stress applied to the substrate can fully transfer to the CFs. However, because of the chemical inertness and low free energy of CF surfaces with high‐density graphitic basal planes, the interfacial bonding is not strong enough to fully transfer the stress from the substrate to the CFs.…”

Advanced active screen plasma (ASP) technology is used to modify polyacrylonitrile‐derived carbon fibre (CF) surfaces using gas mixtures of N2–H2 and N2–H2–Ar. Unlike conventional plasma treatments, ASP treatment can reduce the structural disorder of CF surfaces and increase the surface crystallite size. Moreover, ASP treatment can lead to an increased single fibre tensile strength. This is mainly because the post‐plasma nature of the ASP technology can effectively eliminate ion‐bombardment‐induced degradation while providing radicals necessary for surface modification. The addition of argon to the nitrogen–hydrogen gas mixture contributes to a more ordered graphitic structure on CF surfaces and further increases the single fibre tensile strength. The interfacial properties (interlaminar shear strength and flexural strength) of the resulting composites are improved.

“…Accordingly, the interface plays a pivotal role in stress transfer, the degree of which determines important design criteria including strength, stiffness, and weight. However, the interface bonding of untreated carbon fiber that has large surface inertia and resin matrix is weak which affects the carbon fiber composite material's excellent performance into full play [1][2][3][4]. As a result, extensive research have been devoted to the surface treatment of CF to improve interfacial properties of CF reinforced composites, such as sizing process [5], electrochemical method [6], plasma treatment [7,8] and preparation of graphene oxide (GO)/CF hybrid fiber [9].…”

“…A large number of techniques have been reported to modify the surface of CFs, ranging from the wet chemical processes [4][5][6] to sophisticated RF plasmas, 7 electron beam irradiation, 8 and multistep treatments. 9 However, some of these processes reduce the tensile strength of the fibers, while others are complex, expensive, or inappropriate for large scale implementation.…”

The active screen plasma technology was used to functionalize carbon fibers and vitreous carbon disks. The plasma treatment conditions were mapped using optical emission spectroscopy and the functionalized surfaces were analyzed using scanning electron microscopy and atomic force microscopy, x-ray photoelectron spectroscopy, and contact angle measurements. A relationship was found between the active species in the plasma and the functional groups attached to the carbon surfaces, which provides valuable information for the optimization of the active screen plasma treatment. Moreover, the surface analyses were repeated over a period of 28 days to study the aging of the functionalized surfaces in air. The hydrophobic recovery was modeled using a surface restructuring theory which revealed a mean lifetime of 3.4 days for the functional groups. V
