IMPROVED SOME PROPERTIES OF HIGH DENSITY POLYETHYLENE SYNTHESIS USING FIBER GLASS FOR PIPES AND RESERVOIRS APPLICATIONS

Abstract

In this paper, the effect of surface modification of short glass fiber on some properties of
high-density polyethylene composite was investigated. The chemical treatment of short glass
fiber (SGF) with solvent ethanol was achieved, and composites with weight fraction (0.5, 2.5,
4wt. %) were fabricated. Mechanical behavior tests include (tensile strength, impact, and
hardness tests) and structure test (FTIR) were used. Values of mechanical tests for treated
short glass fiber – reinforced High density polyethylene composites were much better than
the neat high density polyethylene. The tensile strength value of composite from (37 to 41
MPa), impact strength from (83 J/m² to 100 J/m²), and hardness from (64 to 86 N/m²). Result
of FTIR test showed physical reaction without the formation of new peaks.
