Abstract:Continuous carbon fiber reinforced polyetheretherketone (CF/ PEEK) prepreg was produced by slurry
method. Processing temperatures and velocity were investigated.Thermal expansion properties and tensile properties
were also experimented. SEM was used to observe the interface morphology of CF/ PEEK prepreg. The results indica ̄
ted that the temperature distribution in pre ̄heating and melt ̄saturating districts are controlled by 110 to 130℃ and
220 to 370℃.The prepreg velocity is 2 m/ min in order to get good CF/ PEEK prepreg. The thermal expansion property
of CF/ PEEK prepreg is 0.5×10-6 / K in the temperature from -150 to +150℃ꎬthe maximum tensile strength is up to
1.81 GPaꎬ and decreasing with fiber volume increasing.Scanning electron micrograph (SEM) confirms that the inter ̄
face is good between carbon fiber and PEEK. The research tells us that the processing parameters are viable and the
properties of CF/ PEEK prepreg are goodꎬ and can be used in engineering.
