A Simple Laminated Alumina Based Composite with High Work of Fracture

摘要：

　　A kind of laminated composites named Al2O3/Nylon/Al with high work of fracture was prepared by a simple process using epoxy resin adhesives as binder in a leaky mold at a pressure of 5 MPa.Light microscopy and scanning electron microscopy were employed to observe the microstructures and crack propagation of the laminated composites.The flexural strength and fracture toughness were measured through three-point bending test,and the work of fracture of the laminated composites was calculated from the load-displacement curves of three-point bending test.The experimental results show that the composites have low Youngs modulus and flexural strength.However,the work of fracture of the laminated composite appears to be high of 2850 J/m2,and the fracture toughness reaches about 11 MPa·m1/2.Analysis of microstructure and crack propagation reveals that the failure of the laminated composite exhibit distinctive characteristics.
