Abstract : The purpose of this program was to demonstrate the feasibility of developing and incorporating capsular adhesives formulations into an extravehicular astronaut attachment device for stabilization of the astronaut during EVA maintenance or repair missions. Program investigations involved the screening and evaluation of numerous rapid-curing adhesive formulations, encapsulation of adhesive components, testing of capsular adhesive systems, and the design and fabrication of adhesive pads and dispensers. Two potential adhesive systems were selected during the screening studies. These were the Eastman '910' (methyl 2-cyanoacrylate) catalyzed with dimethyl p-toluidine, and epoxy resins catalyzed with BF3 complexes. All of the selected adhesive components were encapsulated and formulated into functional capsular adhesive systems. Because of certain inherent mixing problems which were related to the epoxy resins and the selected cure-inducing catalysts, the majority of work was directed toward the 'Eastman 910' adhesive formulation. Test data obtained in regard to the capsular 'Eastman 910' adhesive formulation indicated the system satisfied the majority of program design goals. (Author)
