Abstract
The invention discloses a PEEK composite material with high heat resistance. The PEEK composite material is characterized by comprising the following raw materials by weight: 77 to 85 parts of PEEK, 6 to 8 parts of silicon carbide ceramic micro powder, 3 to 5 parts of magnesium oxide ceramic micro powder and 6 to 10 parts of zinc oxide ceramic micro powder. The invention also discloses a preparation method for the PEEK composite material. Through filling of PEEK with ceramic micro powder, high temperature resistance of PEEK can be substantially improved, melting temperature increases to 387 DEG C and PEEK can be used for a long time in an environment with a temperature of 330 DEG C and has improved wear resistance and hardness with other mechanical properties barely changed; and the prepared PEEK composite material can be used for a long time in a high temperature environment.
Description
Technical field
The present invention relates to high heat resistance PEEK matrix material and preparation method thereof, belong to field of compound material.
