“…Different fibers such as cellulose [6], Kevlar [7], ceramic [8], carbon [9][10][11], and glass [12][13][14], have also been incorporated into friction materials, leading to improvements in tribological properties. Carbon fibers specifically are used as reinforcement due to their distinctive properties such as self-lubrication, chemical inertness, high strength and modulus, and excellent thermal stability [10,15]. Many papers have reported on the tribological performance of polymer-matrix composites with short or continuous carbon fibers [16][17][18][19].…”

Here, staple carbon fiber fabric-reinforced polycarbonate (PC)- and epoxy (EP)-based composites with different impregnating resin levels were fabricated using a modified film stacking process. The effects of surface topographies and resin types on the tribological properties of stable carbon fabric composites (sCFC) were investigated. Friction and wear tests on the carbon composites were conducted under unlubricated sliding using a disk-on-disk wear test machine. Experimental results showed that the coefficient of friction (COF) of the sCFC was dominated by matrix type, followed by peak material portion (Smr1) values, and finalized with core height (Sk) values. The COF of composites decreased by increasing the sliding speed and applied pressure. This also relied on surface topography and temperature generated at the worn surface. However, the specific wear rate was strongly affected by resin impregnation. Partially-impregnated composites showed lower specific wear rate, whereas fully-impregnated composites showed a higher wear rate. This substantially increased by increasing the sliding speed and applied pressure. Scanning electron microscopy observations of the worn surfaces revealed that the primary wear mechanisms were abrasion, adhesion, and fatigue for PC-based composites. For EP-based composites, this was primarily abrasion and fatigue. Results proved that partially-impregnated composites exhibited better tribological properties under severe conditions.

“…A reverse relationship was noticed for composites with zeolites . What is interesting, composite with modified CB have second tan δ peaks at higher temperature values than composite with CB, which suggest their higher crosslinking density . In the case of previously studied zeolite composites, the crosslinking density was lower for composites with a modified filler.…”

Although phenol-formaldehyde (PF) resins possess excellent properties, they emit toxic substances during the decomposition of the crosslinking agent. Therefore, studies are being carried out on the fillers, which can reduce the amount of crosslinking agent. In this article, the synthesis of diazonium-modified carbon black was conducted. Diazonium modification allows the effective incorporation of hydroxymethyl groups, which are responsible for the crosslinking of PF resins. Modified materials were used as active fillers in the PF composites and abrasive tools. Due to carbon modification, flexural strength increases 26% for PF resin composite and 1100% for abrasive tools. The increase is related to the resulting covalent bonds between the resin and the modified filler. Therefore, it can be stated that application of active filler improves the properties of novolac composites and abrasive tools. The use of this type of fillers may affect the reduction of the amount of crosslinking agent in the future.

Carbon fiber reinforced carbon matrix (carbon/carbon, C/C) composites have become the promising candidates for high‐temperature thermal structure materials in aerospace fields, owning to a series of excellent structural merits. However, for aculeate or thin‐walled C/C composites, due to the fact that continuous carbon fibers are cut off during the machining process and the amount of residual carbon fibers is limited, carbon matrix cannot be effectively strengthened just by using carbon fibers, resulting in a sharp decline in mechanical performance. Furthermore, the rapid development of aerospace vehicles requires that C/C composites not only have excellent mechanical properties but also possess multifunctional properties. To effectively solve these problems and meet the increasing demands, various 1D nanostructures as nanoreinforcements have been introduced into C/C composites, achieving the great improvement in mechanical and functional properties. In this review, the state‐of‐the‐art research activities regarding different 1D nanoreinforcements applied in C/C composites are systematically summarized. Finally, this review is concluded and the future research prospects are proposed. This review provides the “1D nanoreinforcements” strategy to further improve the properties of C/C composites, which could be widely used for reference by researchers in the fields of different fiber/matrix composites.
