摘要
Abstract
In order to study the influence of 3D printing process on the dielectric properties of PEEK,multiple process parameters were chosen to perform a single factor experiment by fused deposition molding technology,and the technologies of nozzle temperature,substrate temperature,printing speed,layer thickness and chamber temperature etc.were studied.The experiment results show that the dielectric constant of PEEK products is the lowest when the nozzle temperature is 400 ℃,the substrate temperature is 140 ℃,the printing speed 30 mm/s,the layer thickness 0.1 mm,and the chamber temperature 120 ℃.The frequency in the 1-100 MHz frequency band has no effect on the dielectric constant.Within the frequency of 1-40 MHz,the dielectric loss tangent of PEEK measured by each process parameter fluctuates drastically,and within the frequency of 40-100 MHz,the fluctuation of dielectric loss tangent of PEEK goes up.The research results provide a basis for the structural design and manufacture of the PEEK dielectric layer of antenna.关键词
