The effect of temperature and chemical solutions on the Compressive strength of particulate hybrid composites

Abstract

In this work a hybrid composite materials were prepared containing matrix of polymer (polyethylene PE) reinforced by different reinforcing materials (Alumina powder + Carbon black powder CB + Silica powder).
The hybrid composite materials prepared are:
• H1 = PE + Al2O3 + CB
• H2 = PE + CB + SiO2
• H3 = PE + Al2O3 + CB + SiO2
All samples related to electrical tests were prepared by injection molding process.
Mechanical tests include compression with different temperatures and different chemical solutions at different immersion times
The mechanical experimentations results were in favour of the samples (H3) with an obvious weakness of the samples (H1) and a decrease of these properties with a rise in temperature and the increasing of the immersion times in the chemical solutions.
