Study on Properties of Epoxy Resin /Al₂O₃ Composites

Abstract:

An epoxy resin/Al2O3 composite was prepared via a new type of process.The effects of Al2O3 content on the mechanical properties and thermal conductivity of the composite were investigated.It shows that the thermal conductivity of the epoxy resin/Al2O3 composite aggrandizes with the addition of aluminum oxide.As the content of Al2O3 is 30%,the thermal conductivity coefficient reaches 0.46W/m·K. Al2O3 particles can hinder the propagation of flaw or make crack change direction.and lead to generate scales flake and islands peak shape on the fracture surface when The thetensile fracture surfaces tested under the liquid nitrogen temperatures(77k). When the mass fraction of Al2O3 is 20%, the mechanics properties of the composite is better
