Abstract

Abstract: Two-dimension self-reinforced PE-HD pipe was prepared using home-made equipment, which was subsequently studied using tensile tester and differential scanning calorimetry (DSC). The axial and circular strength reached 30.56 and 33.5 MPa, 36.6 and 54.6 % higher than those of regular pipe. The axial and circular moduli reached 180.3 and 529.8 MPa, 47.4 and 140.7 % higher than those of regular pipe. DSC showed the degree of crystallinity was improved by 13.51 % and its melting point was improved by 1.5 ℃.

Key words: two-dimensional compound stress field, pipe-extrusion die, HDPE pipe, mechanical property, self-reinforcement
