Abstract
A METHOD IS PROPOSED FOR ESTIMATING REMAINING LIFE OF TEFLON COMPOSITE CHEMICAL/BIOLOGICAL (C/B) SUIT AND ENCLOSURE MATERIALS. THE TECHNIQUE IS BASED UPON THE RELATIONSHIP BETWEEN C/B MATERIAL PERMEABILITY RATE AND SURFACE FRACTURE DENSITY OF FATIGUED MATERIAL. DETECTION OF REMAINING LIFE IS MADE USING SPECIAL NDT PENETRANT MEASUREMENTS WHOSE RESULTS ARE CORRELATED TO PERMEATION RATE VIA FRACTURE DENSITY MEASUREMENTS MADE ON WORN FATIGUED MATERIAL SAMPLES. THE BASIS FOR AN INSPECTION AND RECERTIFICATION PROGRAM FOR C/B SUITS AND ENCLOSURES WILL BE DEMONSTRATED UPON SHOWING PHASE I FEASIBILITY.
