Preparation and Properties of Al2O3/Steel-epoxy Laminated Composites

doi:10.3724/SP.J.1077.2013.12709

Abstract

Abstract:

A series of Al₂O₃/steel-epoxy laminated composites were prepared by using epoxy resin adhesive as binder via a simple process in a leaky mould at a pressure of 5 MPa. The results indicate that the interfaces of Al₂O₃/epoxy and steel/epoxy are joined tightly, and the laminated composites have much higher fracture toughness, impact toughness and energy consumption than the Al₂O₃monolith, as well as having a close strength to Al₂O₃. The crack propagation behavior indicates that the improvement of toughness and energy consumption attribute to the mechanisms of crack blunting and arresting, crack bridging, interface debonding, ductile deformation of steel-epoxy mesh layer.

Key words: laminated composites, alumina, interfaces, steel-epoxy, mechanical properties, toughening mechanism
