Study the erosion resistance of hybrid particulate composites

Abstract

In this work a hybrid composite materials were prepared containing matrix of polymer blend (Novolac 80% + Epoxy 20%) reinforced by different reinforcing materials (Alumina Powder + Silica Powder + Asbestos short fiber ) with two values of volume fraction (30, 40) %.The hybrid composite materials prepared are:•H1 = Blend + Al2O3 + AS (30) %•H2 = Blend + SiO2 + AS (30) %•H3 = Blend + Al2O3 + SiO2+ AS (30) %•H4 = Blend + Al2O3 + AS (40) %•H5 = Blend + SiO2 + AS (40) %•H6 = Blend + Al2O3 + SiO2+ AS (40) % Oxy - Acetylene was used to examine erosion .The sample (H6) of the volume fraction (40%) showed higher erosion resistance values whereas the sample (H1) was less in value to resist erosion, the highest rates of erosion. For the (H1) sample there was high tendency to weight loss with high temperature and less as to the sample (H6).
