Polyether ether ketone is a high-performance engineering plastic, widely used in aerospace, automotive, medical, and other fields due to its excellent physical, chemical, and mechanical properties. This article will explore in detail the advantages of PEEK composite material to help engineers and designers better understand the characteristics of this material.

Basic Characteristics of PEEK Composite Material

High Strength and High Stiffness

PEEK composite material have extremely high strength and stiffness, with a tensile strength of up to 90MPa. They have low water absorption, dimensional stability, excellent gloss, and chemical corrosion resistance. Homopolymer and copolymer are the two main types of POM, the former having higher density, crystallinity, and melting point but poorer thermal stability; the latter exhibits superior thermal stability and resistance to acids and alkalis.

Thermal Properties

PEEK composite material have relatively poor thermal stability and can decompose at high temperatures, releasing harmful gases. Therefore, it is particularly important to control the temperature during processing.

Chemical Properties

Made by a professional PEEK material supplier, PEEK composite materials are resistant to organic solvents, fuels, and lubricants, and can withstand the corrosion of various chemicals. However, they are not resistant to strong acids and bases and are prone to creep and stress cracking in these environments.

Electrical Properties

PEEK has excellent electrical insulation properties, almost unaffected by temperature and humidity. Its dielectric constant and dielectric loss change very little over a wide frequency range, and it has excellent arc resistance, making it suitable for electrical and electronic fields.

Mechanical Properties

The mechanical properties of PEEK composite material are similar to those of metal materials, with high strength and stiffness. Its tensile strength and flexural strength make it an ideal choice to replace metals such as copper, zinc, and steel.

Friction and Wear Properties

PEEK composite material have excellent self-lubrication and wear resistance, with a low coefficient of friction, making them suitable for manufacturing bearings, gears, and other components that require frequent movement and friction.
