The influence of expanded graphite and nano particles TiO2 on mechanical properties of PEEK composites was also be studied here. PEEK is a high performance thermoplastic that is tough, strong, rigid, and creep resistant. However, the tensile modulus kept constant during the change of PTFE content. With the increasing of PTFE content, the tensile strength was increased at first and then decreased rapidly. If the weight percent of short fibers was more than 10%, this increasing tendency became slowly. The results showed, with increasing of the weight content of short fibers, the tensile performance (tensile strength and modulus) of PEEK composites was increased rapidly. The weight content of short fibers, PTFE and expanded graphite was varied from 0-15%, and of TiO2 was varied from 0-8%. Continuous Service Temp / Fair Bearing and Wear Properties.The tensile properties of polyetheretherketone (PEEK) composites, which were reinforced with short fibers, such as short carbon fiber (SCF), short glass fiber (SGF), or filled with polytetrafluoroethylene (PTEF), expanded graphite and nano material TiO2 were examined and studied.

PEEK PVX is an excellent alternative to bearing grade fluoropolymers, it also works well for seal components where ductility and inertness are important. VICTREX PEEK polymer provides exceptional performance over a wide range of temperatures and extreme conditions. PEEK (polyetheretherketone) is a semi-crystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high. A new bearing grade PEEK PVX offers superior bearing and wear performance at elevated pressure and velocity (PV) levels. It is highly resistant to chemicals and thermal degradation. Carbon fiber, Graphite and PTFE reinforced grades provide excellent dimensional stability and increased bearing and wear properties at higher loads. PEEK plastic exhibits excellent physical and mechanical properties. Watch this Tutorial Today The polymer exhibits high volume resistivity and surface resistivity. PEEK offers steam and wear resistance and is now available black making ideal for instrument components where aesthetics are important. PEEK is one of the best heat-resistant materials among high performance plastics. for your High Temperature Composites Applications. Ketron 1000 PEEK stock shapes are produced from virgin polyetheretherketone resin. in hot water and/or steam without permanent loss of physical properties. Physical properties (indicative values g). With a V-O flammability rating PEEK can be used continuously to 480 degrees F. Applications: Wear rings, bearings, fasteners, flat washers, seals, and various applications in the healthcare, transportation, electronics, and aerospace industries.
All grades of PEEK offer excellent chemical and hydrolysis resistance similar to PPS (polyphenylene Sulfide), but can operate at higher temperatures. The four most common grades of PEEK are unfilled, 30 carbon filled, 30 glass filled, and 20 PTFE and graphite filled. Unreinforced grades of PEEK (polyetheretherketone) offer high elongation and toughness. The values shown for AS-4 fibers are typical properties from the manufactures literature (reference 1) while the properties. These properties range from high temperature performance to mechanical strength and excellent chemical resistance. Laminates of three different types of graphite/PEEK. PEEK is a high performance thermoplastic used in many medical and pharmaceutical applications. The graphite/PEEK material used in this study was purchased as 17-inch-long by 17-inch-wide by 0.25-inch-thick laminates.
