Tribological properties of cyclic phenylene sulfide heat‐treated carbon fiber/polyphenylene sulfide composites

Abstract

High-performance self-lubricating polyphenylene sulfide (PPS)/carbon fiber (CF) composites were obtained by treating the CF surface with heat-treated cyclic phenylene sulfide oligomers (CPS). The influence of CPS treat conditions on the structure and properties such as mechanical and tribological performance of the composites were studied in detail. The results indicate that the PPS/CPS-sized CF composites exhibit higher mechanical strength and better tribological performance than the PPS/original CF composites, especially under the condition of higher loads and speeds (300 N Â 200 rpm and 200 N Â 200 rpm). The performance enhancement is reasonably ascribed to the improved compatibility of the modified CF with the PPS matrix. Further structural analysis reveals that the modified CF treated at 300 C under N 2 (CF-300N) has the most similar structure to the PPS matrix, which makes the comprehensive performances of PPS/CF-300N composites superior to the products obtained under the other heat-treatment conditions.

Interfacial strengthening and processing of carbon fibers reinforced poly(ether‐ether‐ketone) composites: A mini‐review

“…Compared with traditional carbon fibers (CF) reinforced thermosetting resin composites, CF reinforced thermoplastic resin composites have the advantages of excellent impact resistance, good wet-heat resistant property, ultrashort molding cycle and recyclable secondary processing. 1,2 Meanwhile, compared with common thermoplastic polymer matrix, such as polyphenylene sulfide (PPS), 3 polyimide (PI) 4,5 and polyether sulfone (PES), 6 poly(ether-ether-ketone) (PEEK) has the excellent heat resistance, humidity and heat resistance, radiation resistance and good flame-retardant properties. 7,8 In addition, compared with common thermosetting resins, such as epoxy resin and organosilicon resin, PEEK has excellent toughness, fatigue stability, and high damage tolerance.…”

Carbon fiber‐reinforced epoxy composite properties improvement by incorporation of polydopamine sizing at fiber–matrix interface

“…Meanwhile, the sizing or coating treatment can enhance the roughness of fiber surface and introduce the interface layer, which advance the stress transfer to the CF. [12][13][14] More importantly, fiber sizing or coating is a convenient and effective method without any loss of fiber inner properties. [15][16][17] Recently, polydopamine (PDA) as a sizing agent for fiber surface modification is greatly appealing to researchers.…”

A review of solid lubrication based on polyurethane composites

“…[29][30][31][32] Polyphenylene sulfide (PPS) has excellent corrosion resistance and radiation resistance with inherent brittleness and low impact strength. [33][34][35][36] PU has unique hard and soft segments to obtain excellent flexibility, and corrosion resistance, which also provide a low COF and wear rate. Considering the tribological properties, PU has become a research hotspot of solid lubricants in the last 10 years.…”
