Enhancement of Wear properties of a polyether ether ketone polymer by incorporation of carbon and glass fibers

Abstract

Some properties of polymers can be improved through the incorporation of carbon and glass fibers into the polymer matrix. In this research, the wear resistance of two polymer composites CF‐polyether ether ketone (PEEK) and GF‐PEEK were compared with the virgin PEEK. The wear resistance was assessed by Pin on Disk tests performed using a range of reinforced polymer pins tested against a steel disk. The influence of load, sliding velocity, counter‐surface hardness, and reinforcement concentration and type, on the specific wear rate was investigated. The materials were chosen to simulate the wear experienced between a polymeric anti‐extrusion ring and a steel sealing surface utilized within valves in the oil and gas industry. The average mass loss was recorded and an analysis of the variance (ANOVA) carried out to investigate the contribution of each parameter on specific wear rate. Results showed that weight percentage reinforcement and type of reinforcement material were primary contributors toward specific wear rate, with a contribution of ~70%. Secondary contributors were sliding speed (~14%) and load and steel hardness (~12%). Following the wear tests, residual stress measurements were conducted on polymer reinforced with carbon fiber. It was found that compressive residual stresses existed, and that their magnitude increased with increasing load. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47587.

Insight into water lubrication performance of polyetheretherketone

“…Previous studies have confirmed that both the lubrication conditions and working conditions highly affect the wear behavior of polymers 16,17 . Similar studies have also been done on PEEK and confirm that PEEK's wear behavior is also highly influenced by the former two factors 18–22 . Laux et al 18 have studied the wear behavior and the transfer film phenomena of PEEK under different working conditions.…”

Antibacterial activity, bio-compatibility and osteogenic differentiation of graphene oxide coating on 3D-network poly-ether-ether-ketone for orthopaedic implants

“…(P < 0.01) increasing resistance to the use of metal implants. As a result, PEEK has attracted attention for use in implants because of its excellent physical and chemical properties [22,23]. Because the high incidence of implant failure is an important cause of peri-implant inflammation, we designed a PEEK implant surface with antibacterial In this study, due to 3D mesh sponge structure, GO nanosheets can be adsorbed to the surface, and the SEM results showed that GO uniformly covered the surface.…”

“…While pure titanium and titanium alloy implant materials have long been used as materials for orthopaedic and dental implants [ 21 ], in recent years, patients have shown increasing resistance to the use of metal implants. As a result, PEEK has attracted attention for use in implants because of its excellent physical and chemical properties [ 22 , 23 ]. Because the high incidence of implant failure is an important cause of peri-implant inflammation, we designed a PEEK implant surface with antibacterial properties that is expected to advance the development of antimicrobial implants.…”

Comprehensive Review of the Properties and Modifications of Carbon Fiber-Reinforced Thermoplastic Composites

“…They stated that the tensile strength and modulus of PET/CF composites increased with an increasing aspect ratio of CF (under the same loading of CF); this increase accompanied the decreased impact strength and elongation at break 20 wt% of the CF. Hamilton et al [105] reported that 20 wt% of CF could increase thermoplastic composites' wear resistance based on the PEEK matrix. Similar observations have been noted by Karsli and Aytac [106], who reported an enhancement of wear properties by incorporating CF into PEEK composites.…”
