“…On the other hand, above the T g , the strain increases because of the intensive motion of polymers' molecular chains. This effect in unfilled polymers is greater than that of in reinforced polymers [21,22]. The effect of temperature and different environmental conditions on the thermoplastic reinforced with GF was studied, and it was observed that a bi-linear reduction in strength and stiffness occurred in the T g range [23,24].…”

The effect of thermal treatment of glass fibers (GF) on the mechanical and thermo-mechanical properties of polysulfone (PSU) based composites reinforced with GF was investigated. Flexural and shear tests were used to study the composites’ mechanical properties. A dynamic mechanical analysis (DMA) and a heat deflection temperature (HDT) test were used to study the thermo-mechanical properties of composites. The chemical structure of the composites was studied using IR-spectroscopy, and scanning electron microscopy (SEM) was used to illustrate the microstructure of the fracture surface. Three fiber to polymer ratios of initial and preheated GF composites (50/50, 60/40, 70/30 (wt.%)) were studied. The results showed that the mechanical and thermo-mechanical properties improved with an increase in the fiber to polymer ratio. The interfacial adhesion in the preheated composites enhanced as a result of removing the sizing coating during the thermal treatment of GF, which improved the properties of the preheated composites compared with the composites reinforced with initial untreated fibers. The SEM images showed a good distribution of the polymer on the GF surface in the preheated GF composites.

“…As distance increased, the specific wear rate eventually decreased. The transition phase between run-in to steady-state phase was closely related to the formation of transfer film where the integrity and development of transfer film affect the specific wear rate and wear mechanism during the sliding event [3], [6], [13].…”

“…Short carbon fibers (SCFs) also show superior properties in wear and friction as investigated by [6]- [9]. Other studies were also in the similar interest and important in a tribological application such as fiber content [5], fiber orientation [10]- [12], temperature [6], [10], and wear conditions [6], [13].…”

The present work investigates the wear properties of nanoclay-modified carbon fiber reinforced polymer (CFRP) composites when sliding under adhesive and abrasive wear. The specimens were fabricated using epoxy resin, short carbon fiber, and nanoclay filler of 1.0wt%, 3.0wt%, and 5.0wt% content. The wear tests were conducted using pin-on-disc and abrasion resistance test rig for adhesive and abrasive wear condition, respectively. Operating parameters were fixed at 30N load, 300rpm speed and 10km distance for both tests. Pure CFRP composite exhibited lower wear performance compared to pure epoxy in both test conditions. However, with nanoclay incorporation, the wear properties of CFRP composite have improved up to 56% and 44% under adhesive and abrasive wear, respectively. Therefore, the composite reinforced polymer of carbon fiber and nanoclay filler in epoxy matrix provides a synergistic effect under adhesive and abrasive wear conditions. The experimental findings suggest that the CFRP composite has the potential for tribological components and application such as sliding-contact and rolling-contact bearings.

“…Polyetheretherketone (PEEK), especially carbon fiber (CF) reinforced PEEK composites, are promising materials in aerospace, automobile manufacturing, medical equipment, insulation materials due to their excellent comprehensive properties such as ultrahigh tensile strength, ultrahigh bending strength, self‐lubrication, and corrosion resistance . For most fiber‐reinforced PEEK composites, the strong adhesion, compatibility and wettability between the filling material and the matrix are key issues that must be addressed .…”

Polyimide (PI) as a sizing agent for short carbon fiber (SCF) was explored, and a series of SCF-reinforced polyether ether ketone (PEEK) composites with PI sizing concentrations varying from 0 to 2.0 wt % were fabricated using the extrusion and injection molding techniques. It was found that the PI sizing layer forms homogeneously and compact on the SCF surfaces, and when the PI sizing concentrations was 1.0 wt %, the tensile strength and flexural strength of the corresponding SCF/PEEK composite was significantly increased by 16.8 % and 8.2 % respectively in comparison with the untrelated case. Additionally, dynamic mechanical analysis (DMA) curves demonstrated that storage modulus of SCF/PEEK composites were enhanced with the increasing concentration of PI sizing, resulting the higher stiffness and the lower damping behavior of the composites. Further, the single fiber pull-out testing was also measured, with the increased interfacial shear strength (IFSS) of CF/PEEK composites by 24.8 % from 70.6 to 88.1 MPa for the CF modified with 1.0 wt % PI sizing, which illustrated that PI sizing can improve fiber surface wettability and interfacial adhesion between CF and PEEK.
