MODIFICATION THE CHARACTERIZATION OF EPOXY POLYESTER BLEND BY USING TITANIUM DIOXIDE FILLER

Epoxy resin blended with Unsaturated polyester resin and filled with TiO2 filler. ultrasonic mixing process. TiO2 nanoparticles were used as reinforcement in prepared by cast molding method with filler volume fractions (0%,1%, 2%, and 3% ). The thermal conductivity constant, hardness, compression strength, wear, impact strength and DSC were studied. Compression strength, wear loss, thermal conductivity constant, DSC, FTIR, UV, atomic force were studied. The experimental results showed that the thermal conductivity constant decrease, hardness increase with filler content increase . Titanium dioxide content in epoxy/polyester blend matrix was dispersed and investigated by using ultrasonic technique .Sample four give the maximum value of compression strength. The glass transition temperature, melting point and degree of crystallization decrease by adding titanium dioxide
