The effect of component distibution varition on bending modulus of gradient Interpenetrating polymer networks (IPN)

摘要：

　　In the paper,the mathematic model of bending modulus was established by means of classic mechanical theory,Layer number and gradient factor K were used to control component distribution of gradient IPN.Polyurethane(PU)/Epoxy(EP) gradient IPN with different component distribution were prepared,The effect of component distribution variation on bending modulus of gradient IPN was studied.The results indicated that bending modulus of gradient IPN decreased with increase of layer number n and gradient factor K,the gradient factor K had greater effect on bending moulus of gradient IPN than layer number.The results were explained according to bending rigid coefficient distribution of singel layer calculated by the mathematic model.
