HTPB PROPELLANT DEBONDING DAMAGE RESEARCH

摘要：

HTPB propellant is the high filled particulate elastomeric matrix composite.Debonding of particle/matrix interfaces can significantly affect the macroscopic behavior of composite propellant.How to model the propellant material and describe damage processes has been a long-standing question.This paper used an nonlinear cohesive law for particle/matrix interfaces to study interface debonding.By analyzing the damage evolution in two model particulate composite systems with finite element method,the scheme was shown to capture effects associated with the interface strength and nonuniform particle spacing and size.
