The Effect Of Temperatures and Chemical Solutions on The Elasticity Modulus Of Hybrid Composite Materials

Abstract

In this one of the work a hybrid composites materials were prepared whichconsist polymer blend – Phenol formaldehyde – Novolac type and epoxy resinsreinforced by silica, alumina powder and asbestos fibers with two volumefractions (30%, 40%), six hybrids prepared. Bending test was done in order todetermine the Young's modulus in different temperatures and different chemicalsolutions. the result show that Young's modulus decreases with increasingtemperatures and with increasing the immersion times in different chemicalsolutions , and the result show that the samples H6 (Volume fraction 40%) giveshigh values of young modulus while the samples H1 (Volume fraction 30%) giveslow values of young modulus
