摘要: Abstract The present paper is dealing with the reinforcement of high density polyethylene (HDPE) matrix using pre-dried graphene nanoplatelets (GNPs). Nanocomposites three different wt GNPs contents, i.e. 1%, 2% and 3%, were produced. so-obtained extruded GNPs/HDPE nanocomposites underwent both tensile three-point bending tests. Ultimate strength was not affected by content. However, response on plastic deformation under loading differed in each case, depending microstructure produced nanocomposites. Due to weak Van der Waals forces that bond layers into a GNP, these are allowed slip in-plane level they observed dislocated after loading. Pores concentration detected for contents greater than 1%. flexural enhanced values also correlated dimensions pores formed.
