Abstract Rare earth modifier (RES) and phenyl trimethoxy silane (PTMS) were used for the surface treatment of milled glass fiber (MGF) with different ratios. The composites were prepared by modified milled glass fiber powder and PTFE aqueous dispersion with hot pressing method after mechanical mixture. The effect of mixing ratios of RES/PTMS components on the dielectric properties, coefficient of thermal expansion and heat conduction properties of MGF/PTFE composites were investigated. FTIR spectra of RES, unmodified and modified of MGF were tested, and then the fracture surfaces were analyzed by SEM. The experimental results showed that mixing ratios of RES/PTMS components could promoting interfacial adhesion between the glass fiber and PTFE. Which was an effective way in improving the properties of the composites. The optimal performance of the prepared MGF/PTFE with the mass fraction of RES and PTME of 0.3% and 1.7% respectively.
