Influence of the addition of lubricant on the properties of poly(ether ether ketone) fibers

Polymer matrix composites have revealed enormous potential to substitute metal components in a wide variety of applications because of their self-lubrication properties, lightweight and resistance to wear, corrosion and organic solvents. However, additional upgrading in their properties is still essential. The endeavour of this research was to assess the effect of the material type and the morphology of multiwalled carbon nanotubes (MWCNTs) on the wear performance of poly-ether-ether ketone (PEEK) matrix composites. The MWCNT-filled PEEK matrix composites were prepared using melt mixing technique. The wear behaviour of reinforced MWCNT-filled PEEK composites was studied using the pin-on-disc apparatus under dry sliding conditions at different applied loads, sliding speeds, temperature and wt% MWCNTs. Experiments were conducted using response surface methodology (RSM)-based central composite design. The specific wear rate and coefficient of friction were considered as wear performances of MWCNT-filled PEEK matrix composites. The second-order models are developed to optimize the wear parameters using the genetic algorithm technique. The morphologies of the worn surfaces were observed by scanning electron microscopy.

“…Compared to other polymer materials, poly‐ether‐ether‐ketone (PEEK) has shown promising tribological properties and the ability to service at continuous high temperature to 250°C . As a high‐performance semicrystalline thermoplastic polymer, PEEK exhibits a high thermal‐mechanical property, low flammability, and chemical resistance, which makes it frequently use as a replacement for metals in a variety of high‐performance end‐use applications . Additionally, it can easily be processed in various complex shapes and also make them possess high toughness and excellent wear resistance .…”

In this study, the high-temperature tribological behaviors of poly-ether-ether-ketone (PEEK) under fretting wear condition have been evaluated by using a SRV-IV oscillating reciprocating ball-on-disk tribometer. It can be found that the noticeable transitions of the friction coefficient and wear rate occurred when the test temperature was 1508C. Based on the observations of the morphologies of worn surfaces, the transition of wear mechanisms of PEEK actually occurred at 1508C. In addition, by investigating the change of the crystalline structure of PEEK, results showed that the wear contributed to the formation of a higher crystallinity of PEEK. The change of the crystallinity further affected the tribological behavior of PEEK. According to the result of permanganate etching, it also can be observed that the main component of plastic deformation resulting from adhesive wear was the amorphous phase.

“…Due to their superior properties, PPS and PEEK systems are widely used in aerospace, automotive, electrical, and medical industries . However, high melting temperatures and viscosities of these resins limit their processability and increase the cost of manufacturing . Several efforts have been made to improve the processability of PPS and PEEK by blending with rheology modifiers such as oligomers, lubricants, and hyperbranched polymers that typically result in a sacrifice of thermal and/or mechanical properties .…”

Polyhedral oligomeric silsesquioxane (POSS) additives have been shown to increase melt-flow and crystallization in thermoplastics. In this study, the effect of incorporation of trisilanolphenyl-POSS molecules in polyphenylenesulfide (PPS) and polyetheretherketone (PEEK) on rheology, crystallization kinetics, and thermal and mechanical properties was evaluated. Parallel plate rheometry revealed a reduction in the viscosity of PPS and PEEK with the addition of POSS. The magnitude and concentration dependence of rheological modification were shown to depend on the polymer structure and POSS solubility. Isothermal crystallization kinetics were analyzed using the Avrami model and it was found that the addition of POSS accelerated the crystallization rate of PPS blends with no significant effect on PEEK blends. Interestingly, no statistical difference in degradation temperature, tensile modulus, or tensile strength of PPS or PEEK blends was observed. The findings indicate the potential for improvements in melt viscosity and crystallization of high temperature thermoplastics with tailored POSS/polymer interactions. V C 2016 Wiley Periodicals, Inc.
