HIGH-ENERGY BALL MILLING OF Al–Cu–Fe QUASICRYSTAL-REINFORCED COMPOSITE POWDERS BASED ON POLYPHENYLENE SULFIDE
ABSTRAKT
The process of formation of composite powders based on polyphenylene sulfide reinforced with i-Al–Cu–Fe quasicrystals was investigated. High-energy ball milling in a planetary ball mill was applied to produce composites from an initial mixture of polymer and quasicrystalline powders. The influence of ball milling regimes on the structure of both pure polyphenylene sulfide and composite powders was investigated. It was found that using more intense regimes of ball milling leads to a noticeable increase in the size of polymer powder particles because of the agglomeration occurring in milling. Differential scanning calorimetry and X-ray analysis show the results of milling in partial amorphization of polyphenylene sulfide. It was observed that ball milling for 30 min at a carrier rotation rate of 200 rpm is an optimal regime, which, on the one hand, allows one to reach homogeneous filler distribution in the polymer matrix, and, on the other hand, to keep the initial structural and morphological characteristics of the initial polymer.
