WANG Weipan, ZHANG Fengying. STUDY ON MECHANICAL PROPERTIES OF ULTRA-HIGH MOLECULAR WEIGHT POLYETHYLENE[J]. Acta Polymerica Sinica, 1996,(4):499-502.DOI:
crystalline and flexble polymers can gain higher mechanical properties through extra-drawing' In the paper
the effect of drawing conditions on structures and properties of ultra-high molecular weight polyethylene (UHMWPE)'during two-stage drawing was studied' Results showed that during super-drawing
elastic modulus (E) and break strength (o) increased with drawing ratio (a) Attemperature Td= 150 ℃; when a=60
the perfect mechanical state was abtained
and at this time
E and a were in the highest(E=130.44GPa
σ=3.86Gpa)
34 and 29 times of those by onestage (cold) drawing respectively.
