The effect of alumina nanoparticles addition on the Shear and Thermal propertiesof glass fiber reinforced epoxy composites

The purpose of this study was to evaluatethe Shear and Thermalproperties of glass fiber/nano alumina reinforced epoxy composites and to investigatethe effect of different contents of alumina nanoparticles of 0.5, 1 and 1.5 phraddition on this composite. Lap shear strength, Interlaminar shear strength, Gel time tests and DSChave been used for this evaluation.Results show that the Interlaminar shear strength of satin glass fiber epoxy composite increased from 45.6 to 53.5 MPa by adding 0.5 phrnano-alumina particles and then reduced to 38.1 Mpa by adding 1 phr nanoparticles and then we have a relative increase again, by adding 1.5phr nanoparticles. Lap shear strength satin glass fiber epoxy compositereduced by addingnano-alumina particles. alsoGel time of epoxy resin reduced by adding nanoparticles and raising tempreature from 100˚c to 120˚c.
