碳纤维聚醚醚酮颗粒
聚醚醚酮不仅具有优异的机械、耐热和耐化学性能，而且具有低摩擦系数和良好的承载啮合。它是继聚四氟乙烯（PTFE）之后的另一种良好的自润滑材料；其承载能力和性能均高于聚四氟乙烯。它可以用作轴承、齿轮、活塞环和柔性密封件等部件的材料，并且可以在无润滑、低速和高负载、高温、潮湿、污染和腐蚀等恶劣环境中使用。CF不仅增强了聚合物，而且对其摩擦学性能有重要影响。用销盘摩擦试验机研究了30%短碳纤维增强聚醚醚酮复合材料在20～225℃高温下的干摩擦磨损性能。结果表明，玻璃化转变温度以下的Tg复合材料的刚度显著提高，磨损率较低，摩擦系数高于纯PEEK；当温度超过Tg时，玻璃化转变引起的热软化使两者的**性能下降，但复合材料性能的恶化要好得多。由于CF的增加应抵消PEEK的热软化，并形成非常高强度的转移膜，以有效保护接触面积，因此CF/PEEK的摩擦系数和比磨损率显著低于纯PEEK。研究了CF/PEEK在-196℃液氮中的摩擦磨损性能。结果表明，该材料在低温环境下的摩擦磨损性能比室温下差，主要受基体树脂的控制。热塑性工程树脂一般略优于热固性树脂；CF用量对CF/PEEK摩擦磨损性能的影响不如室温下明显。当质量分数为5%和15%时，摩擦系数和磨损率都比较理想

Product Details
carbon fiber PEEK pellets
PEEK not only has excellent mechanical, thermal and chemical resistance properties, but also has a low friction coefficient and good load-bearing meshing. It is another good self-lubricating material after polytetrafluoroethylene (PTFE); and its load-bearing capacity and performance are higher than that of PTFE. It can be used as a material for components such as bearings, gears, piston rings and flexible seals, and can be used in harsh environments such as no lubrication, low speed and high load, high temperature, humidity, pollution, and corrosion. CF not only strengthens the polymer, but also has an important influence on its tribological properties. The dry friction and wear properties of 30% short CF reinforced PEEK composites at a high temperature of 20-225℃ were studied with a pin-disc friction tester. It is found that the stiffness of the Tg composite material below the glass transition temperature is significantly improved, the wear rate is low, and the friction coefficient is higher than that of pure PEEK; when the temperature exceeds Tg, the thermal softening caused by the glass transition makes the ** performance of the two decline, but the composite The deterioration of the material’s performance is much better. Since the increase of CF should offset the thermal softening of PEEK and form a very high-strength transfer film to effectively protect the contact area, the friction coefficient and specific wear rate of CF/PEEK are significantly lower than pure PEEK. The friction and wear properties of CF/PEEK in liquid nitrogen at -196℃ were studied. It is found that the friction and wear performance of the material in low temperature environment is worse than that at room temperature, which is mainly controlled by the matrix resin. The thermoplastic engineering resin is generally slightly better than the thermosetting resin; the effect of the amount of CF on the friction and wear performance of CF/PEEK is not as obvious as that under room temperature. When the mass fractions are 5% and 15%, the friction coefficient and wear rate are ideal.
