Abstract

Self-reinforced Polymerized HDPE monofilament were prepared by die drawing process. According to Cox model for fiber composite and Gibson & Ward crystalline bridges′ model

the reinforced mechanism was discussed to reveal that the mechanical improvement of monofilament was due to the growth of needlelike crystal with larger aspect ratio or the increase of volume fraction of the crystalline bridge. Based on the experimental results obtained by DMA

DSC and SEM

the theoretical prediction was also analyzed and disussed

and found the theoretical values could well-explain the monofilament behavior.
