    Abstract

    Solid-phase die-drawing of composites with semi-crystalline polyolefins and particulate filler is a new process for producing expanded and oriented structural materials 1-2. The objective of this work was to investigate the maximum draw ratio attained with composites of isotactic polypropylene and talc and the polymer chain-axis orientation obtained over various draw ratios at 10°C below the melting temperature. The maximum attainable draw ratio with the PP-talc composite was considerably greater than with the neat PP. The extent of debonding and void growth was well advanced before significant orientation was developed in the crystalline lamellae of the polypropylene matrix.
