“…Moreover, the deeper and narrower ridges were observed from both the studies, which are in accordance to the literature [19]. The fine striations on the untreated fiber surface were due to the spinning of the fiber precursor [20]. The average surface roughness (R a ) values for untreated and treated fibers were 38.4 nm and 66.3 nm, respectively, which confirmed the increase in surface area and alteration in the morphology.…”

The new technique to tailor carbon fabricpolyethersulphone (CF-PES) composite surface with polytetrafluoroethylene (PTFE) nano particles; to improve wear performance has been reported. Cold remote nitrogen oxygen plasma (CRNOP) treatment was employed to alter the CF surface to promote fiber/matrix adhesion and further; inter laminar shear strength and wear performance of the composites. The atomic force microscopy and high resolution transmission microscopy; studies confirms the topographical modification on the fiber surface due to CRNOP treatment. The dipper ridges and perforations introduced on the fiber surface were analyzed with field emission scanning electron microscopy. The PTFE particles film formation on the worn composite surface was supportively analyzed by Raman spectroscopy and energy dispersive X-ray techniques. The topographical smoothening and rolling effect during the wearing of surface designed composites with PTFE nano particles; endorse to enhance its sliding wear properties and life.

“…[2] Interaction between fiber and matrix is very important to transfer load from fiber to matrix as a result of proper interaction between fiber and matrix material, so surface modification of fiber is necessary to enhance interaction. [3] CF surface treatment methods include chemical oxidation, [4] ozone treatment, [5] anodic oxidation, [6] plasma treatment [7] as well as gaseous oxidation. [8] Polysiloxane coating for polymer composites has been investigated for natural fibers.…”

The aim of this work was to improve mechanical properties such as flexural strength and interlaminar shear strength (ILSS) of polyetheretherketone (PEEK) thermoplastic polymer which has very high processing temperature due to its high melting temperature. Carbon fiber (CF) surface was modified by two different methods: oxidative and non-oxidative. Piranha solution and chromate solution were used for chemical treatment (oxidative treatment), and silicone based polymers were used for polymer coating (non-oxidative). The changes on the surface structure and surface chemistry were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy (FTIR), respectively. FTIR results indicate that coating fibers decreases carbon element content, whereas increases the oxygen and silicone content as well as their functional groups on the surface. Flexural strength and ILSS properties of CF/PEEK composites were measured according to ASTM D-790 and ASTM D2344, respectively.

“…4B) indicates that the carbon atoms are involved in several chemical environments. The peaks at 285 and 286.7 eV are related to the graphitic structure, C-C/C-H and C@O, respectively [25][26][27]. However, the binding energy at 285.1 eV was assigned to C-C bonds associated to the phthalocyanine ring, this assumption is supported by the C 1s Be observed for (SiPy + ) 4 CoPcTs À4 , see Table 1.…”
