Abstract
In this paper, the effect of surface modification of short glass fiber on some properties ofhigh-density polyethylene composite was investigated. The chemical treatment of short glassfiber (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, andhardness tests) and structure test (FTIR) were used. Values of mechanical tests for treatedshort glass fiber – reinforced High density polyethylene composites were much better thanthe neat high density polyethylene. The tensile strength value of composite from (37 to 41MPa), impact strength from (83 J/m² to 100 J/m²), and hardness from (64 to 86 N/m²). Resultof FTIR test showed physical reaction without the formation of new peaks.
