Specific effects of PEEK carbon fiber reinforcement
Mechanical performance improvement: The addition of carbon fiber significantly enhances the tensile strength, flexural strength, and compressive strength of PEEK. For example, the bending strength of CF/PEEK composite material with 30% carbon fiber content can reach over 300MPa, while pure PEEK is only about 170MPa.
Enhanced heat resistance: The thermal deformation temperature of carbon fiber reinforced PEEK is significantly increased, allowing it to maintain its mechanical properties and dimensional stability at higher temperatures. For example, the thermal deformation temperature can exceed 300 ℃.
Improved wear resistance: The addition of carbon fiber reduces the friction coefficient of the material, improves wear resistance and friction reduction performance, and is suitable for high load and high wear working conditions.
Improved anti fatigue performance: Carbon fiber suppresses microcrack propagation by bridging cracks, and the plastic deformation ability of PEEK matrix absorbs cyclic load energy, forming a dual anti fatigue mechanism of "fiber crack resistance+matrix energy dissipation".
Application Area
PEEK carbon fiber reinforced materials have wide applications in multiple fields:
Aviation and aerospace: used for manufacturing aircraft components, engine parts, etc., due to their characteristics of lightweight, high strength, high temperature resistance, and fatigue resistance.
Military industry: used to manufacture high-strength and high durability weapon and equipment components.
Nuclear power: used to manufacture key components of nuclear power plants due to its radiation resistance and high temperature resistance.
Automobile: Used for manufacturing lightweight and high-strength automotive components, such as engine compartment parts, transmission systems, etc.
Through these characteristics, PEEK carbon fiber reinforced materials perform excellently in various extreme environments, meeting the requirements of high precision and high reliability.
