![]() ![]() We can also machine them to produce prototypes or high performance parts in series. For all fatigue tests under fully-reversed multi-block loadings, pre-loading was found to have a significant beneficial effect on PEEK fatigue resistance irrespective to the load sequence. We can transform these materials into tube, bar, plate. increasing the test frequency generally resulted in longer fatigue lives for PEEK, while a minimal effect of tensile mean strain was observed. We have the expertise and equipment to process PEEK, as well as many other engineering plastics: PCTFE, PTFE, PFA, PVDF, Polyimide, PEI, PES, PSU, ETFE, PES, PA, POM, PPS and PAI. DEMGY, your specialist in the transformation and machining of high performance plasticsĭEMGY has been working for more than 80 years now in the processing of high performance plastics. This thermoplastic is available on the market under the following trade names: Grade 450 (Victrex®), Vestakeep® (Evonik), Kepstan® (Arkema), KETRONPEEK®, SUSTAPEEK® and TECAPEEK®. Effects of processing variables on fatigue in molded PEEK and its short fiber. Its performance is also highly valued in the medical and electronics industries. composite materials are quite complex and not yet completely understood. According to the material property data sheets for Victrex PEEK, an increase in molecular weight results in an increase in the impact on strength/toughness. In the aeronautics industry, it replaces heavier and therefore more energy-consuming metal components. It is therefore very popular in the automotive, aerospace and semiconductor industries. Thanks to its many qualities, PEEK is very much in demand in environments subject to high mechanical stress. Polyetheretherketone (PEEK) material is a polycyclic, aromatic, thermoplastic polymer that is semi-crystalline and has a linear structure. The static tensile measurement, tension-tension fatigue. It is also highly resistant to wear and abrasion. Fatigue behavior of carbon fiber reinforced poly(etheretherketone)(PEEK) laminates was investigated. It also resists creep, even under high temperatures. In particular, it remains unaffected by attacks from organic solvents at room temperature. PEEK also resists well to hydrolysis and to the long-term action of chemicals. This engineering plastic can withstand a constant temperature of 250☌, but its melting temperature is 340☌. Under cyclic loading, PAN CFR PEEK demonstrated an increased resistance to FCP compared with. It derives its unique properties from the polymerization of ether bonds with polycondensation-type kinetics. Fiber type did not have a significant effect on failure strain. The improvements in monotonic and FCP behavior of PAN CFR PEEK is attributed to a compound effect of inherent fiber properties, increased fiber number for an equivalent wt reinforcement, and fiber aspect ratio. PEEK is a rigid polymer with a low coefficient of friction and low moisture absorption. Pitch CFR PEEK exhibited FCP behavior similar to unfilled PEEK, and neither material was appreciably affected by annealing. About the specific characteristics of PEEK It is also known for its high operating temperature and low density compared to metals. PEEK is a high performance material, known for its high resistance to creep, fatigue, impact and high energy radiation.
