                 Abstract:  PEEK  and  PEI  are  high-performance  engineering  plastics  with  excellent  mechanical  properties,  heat
                 resistance, chemical stability and chemical corrosion resistance. They are often used in machining and aerospace fields.
                 In this paper, four different contents of Carbon fiber were added to the MWCNT+PEI/PEEK layered structure PEEK
                 phase. Carbon fiber has extremely high axial strength and modulus, can withstand high stress and deformation, and has
                 excellent  thermal  stability,  which  is  suitable  for  high  temperature  working  environment.  By  testing  the
                 thermogravimetric analysis, quenched surface and tribological properties of CF/PEEK, the effect of Carbon fiber content
                 on the layered structure and properties were systematically studied. Thermogravimetric tests showed that the thermal
                 decomposition temperatures of all CF/PEEK composites were higher than 554 ℃, indicating that they showed excellent
