PEEK is one of the most expensive plastics on the market, but its outstanding properties make it the go-to choice when you need an incredibly strong plastic that will remain dimensionally stable under load and in the harshest environments. PEEK can also be reinforced with other materials to enhance its abilities. In particular, carbon PEEK material properties are useful for high load applications, such as aircraft mechanical components and oil and gas processing equipment.
Carbon PEEK has been reinforced with carbon fiber, giving it the highest strength and stiffness of all the PEEK grades and improving its load-carrying capacity. It is also 7% lighter than glass reinforced grades, even though it contains more reinforcement per unit volume. The carbon fiber gives it a significantly higher thermal conductivity compared to unreinforced PEEK, thus reducing its thermal expansion rate. With the highest chemical resistance of any semi-crystalline plastic and excellent retention of mechanical properties up to 300ºC (572ºF), carbon PEEK can replace metal in some of the harshest environments.
Carbon PEEK is used in a wide range of industries and in a variety of applications. Its substantial durability makes it a common choice for punishing environments. Typical applications include:
Carbon PEEK material properties – particularly its high temperature resistance – can make it difficult to process. However, in its solid state, PEEK is readily machinable by CNC milling machines. Machining PEEK is the preferred method in most high-precision applications where components need to offer excellent mechanical and wear properties.
