Abstract:
The motivatitni for" the present work is from .a
project sanctioned by TSRO. The work involved the development
of a quick and reliable test procedure using
microwaves, for tflue inspection of cured propellant samples
and a method to monitor the curing conditions of propellant
mix undergoing the curing process.Normal testing CHE the propellant samples involvecuttimg a piece from each carton and testing it for their tensile strength. The values are then compared with standard ones and based on this result the sample isaccepted or rejected. The tensile strength is a measure ofdegree of cure of the propellant mix. But this measurementis a destructive procedure as it involves cutting of the sample. Moreover, it does not guarantee against nonuniform curing due to power failure, hot air-line failure,operator error etc. This necessitated the need for the development of a quick and reliable non-destructive test
procedure.
