HDPE-Quasicrystal Composite: Fabrication and Wear Resistance

摘要

The present paper reports, for the first time the processing, characterization and wear property of novel HDPE-decagonal quasicrystal (QC) composite prepared by the compression molding technique. The composites are prepared at 130°C at applied pressure of 735 kPa with different holding time to obtain fully dense product. It has been found that a holding time of 60 min is the optimum at the specified molding temperature and pressure. The second phase (QC) content is varied from 5 to 20 wt% to obtain optimum mechanical properties. SEM observations indicate well-dispersed QC particles within the HDPE matrix, with fine scale distribution for 20 wt% QC. Ballon-disc wear test reveals that composites showing better wear resistance than pure HDPE sample. The results are discussed using currently available literature.
