Improvement of the Impact Strength Properties for Nanocomposites Based on Polymers

Abstract

This study aims to prepare composite materials and improve some of their mechanical properties by using epoxy resin (EP) and polyurethane (PU) as the matrix material and nanoparticles (Al2O3) as reinforcing agents in different ratio with weight fractions (5%, 10%, and 15%). The results in the tables show that increasing the weight fraction of nanoparticles leads to an increase in the elasticity coefficient and durability of the impact and absorbed energy, with an increase in the temperature of the composite material reinforced with nanoaluminum oxide particles. The mechanical properties gradually decrease with the increase of the period of immersion in water.
