    Abstract

    The effects of liquid N2O4 and monomethyl hydrazine on the breaking strength of the propellant handlers ensemble fabric versus time of exposure were determined. The breaking strength of the fabric was found to vary inversely with the time of exposure to N2O4, but was not found to be affected by exposure to monomethyl hydrazine for periods up to 60 minutes. It was found that the time of exposure of the fabric to N2O4 could be determined by differential scanning calorimetry (DSC) analysis and that a correlation exists between the breaking strength of the fabric and an endothermic event occurring during DSC analysis of the fabric.
