“…Polymer materials have an excellent strength-to-weight ratio and possess excellent tribological properties. Examples include thermoplastics such as polybutylene terephthalate (PBT) [17], polyamide (PA) [12,21], polyetheretherketone (PEEK) [22,23], and polycarbonate (PC) [24,25]. Most of these materials are semi-crystalline polymers that have a low glass transition temperature (Tg).…”

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.

“…One of the most effective methods to enhance the tribological properties of polymer composites is to fill them with some other materials, like graphene, carbon nanotubes, graphite, transition metal disulfide, carbon fiber, etc. As for metallic oxide, soft nanoparticles like CuO, Bi 2 O 3 and hard nanoparticles like ZrO 2, TiO 2 can all enhance the mechanical properties and tribological performances of polymer composites to some degree.…”

In this paper, different morphologies ZnO (disk‐like, rod‐like, and nanoparticles) were introduced into phenolic composite coatings to comparatively investigate the tribological properties. The structural and morphological characterization was conducted with Raman spectroscopy, X‐ray diffraction, and scanning electron microscopy. The tribological performances of composite coatings were evaluated using ring‐on‐block tester under dry condition at room temperature. Experimental results indicated that composite coatings filled with 1 wt% ZnO micro‐disks possessed the optimal tribological performances. It was attributed to the strong interfacial interaction between ZnO micro‐disks and phenolic matrix induced by their specific polar structure. Moreover, different loads and sliding speeds were employed to further evaluate the tribological performances of ZnO micro‐disks/phenolic composite coatings. The outcome revealed that ZnO micro‐disks were potential anti‐wear fillers under harsh condition.

“…Polymeric composites have been increasingly used in various industries due to their lightweight properties and high in specific strength and stiffness [1]. They are also popular as sliding materials against metallic counterparts as they possess unique features such as self-lubrication capability, chemical stability and low in weights [2]. Polymer and their composites are increasingly used as bearing materials, rollers, seals, gears, cams, wheels and clutches.…”

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.
