Al2O3/Steel-epoxy层状复合材料的制备和性能
Preparation and Properties of Al2O3/Steel-epoxy Laminated Composites
摘要
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 Al2O3 monolith,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.关键词
