INFORMATION OBTAINED FROM INVESTIGATIONS CONDUCTED INDICATES THAT THERE ARE MANY FACTORS TO BE CONSIDERED IN SELECTING THE PROPER MATERIALS OF FABRICATION FOR SOLID PROPELLANT PROCESSING FACILITIES. Selecting the proper materials of fabrication can reduce the impact and friction hazards significantly. The impact and friction tests are excellent tools for dividing materials into general classes of usefulness. Although studies of the factors influencing impact and friction results are not complete, the modulus of compression, hardness, and coefficient of friction are some of the major factors to be considered. Consideration must be given not only to the impact and friction results and such factors as modulus of compression and coefficient of friction, but also thermal and electrical conductivity, structural strength, load bearing characteristics and dimensional stability. In addition, complete analysis with testing under simulated conditions is required to insure that the expected improvement is realized and does not create an unforeseen hazard.
