This evaluation report summarizes research and development work on fragment-resistant plastic laminates for use as components of personnel armor assemblies carried on during the period 1 November 1948 - 31 August 1949. Preliminary evaluations have been made of promising resins based upon formulations of phenol formaldehyde and polyvinyl butyral. These promise to provide a better armor characteristics at lower cost than has been true of resins previously evaluated. Preliminary evaluation have also been made of several new types of fabrics, i.e. Fortisan, Orlon, and Fiber V. Studies have been made of the effects of forming into helmets, exposure to accelerated and natural aging, and salt sprays. Reductions in ballistic values under these exposure conditions were small. In the transparent armor program, newly available transparent back-up films have resulted in improved clarity with no appreciable change in ballistic value.
