  Abstract

Carbon fiber reinforced polyether-ether-ketone (CF/PEEK) composite materials had a wide range of applications in the aerospace, electronics and electrical fields, etc. The composite materials were generally prepared from prepregs. Commonly used prepreg tape preparation methods had disadvantages of uneven resin distribution and inadequate fiber impregnation, resulting in high porosity and poor mechanical properties. In this research, a combined process of the double powder impregnation method and the melt homogenization method was used to prepare the CF/PEEK prepreg tape to solve the previous problems. Using this method, the porosity of the prepreg tape was reduced by 56.30 % and the tensile strength was increased by 43.35 % compared with the traditional powder impregnation method. At the same time, the prepreg tape was widened and thinned and the uniformity of resin distribution was improved. Besides, based on the single factor experiment, the response surface method was used to construct the impregnation model of the quadratic polynomial regression equation between the process parameters (powder impregnation temperature, traction speed and melt homogenization temperature) and the porosity of the CF/PEEK prepreg tape. According to this model, the process parameters for the porosity of the prepreg tape were calculated to reach the minimum, namely, the powder impregnation temperature was 380 , the traction speed was 1 m/min, and the melt homogenization temperature was 380 . As a result of these process parameters, the porosity of the prepreg tape could be reduced to 7.39 %. Subsequently, the model was verified through experiments, which could provide a reference for the process parameters setting of the impregnation process.
