A Structural Integrity Perspective for the Assessment of Ageing in Composite Solid Propellants
Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT Composite solid propellants (CSPs) are critical materials in the defence and aerospace industries, known for their complex mechanical behaviour and susceptibility to ageing. This study explores the application of Principal Component Analysis (PCA) to discriminate the ageing degradation of CSPs based on structural integrity parameters.
