Measuring Interface Elastic Modulus of NEPE Propellant/Liner by Indentation Method

Through indentation method and test data processing, the interface and body elastic modulus of NEPE propellant/liner was gotten. The results show that the elastic modulus of propellant/liners interface was lower than that of the propellant body. Under the condition of aging at 65 ℃, the elastic modulus of the propellant body and the interface both increased, but there was difference between the elastic modulus changing of interface and body.
