A series of laminates was prepared using plasticized polyvinyl chloride. polymethyl methacrylate, and Plaskon 920 as the binders for 2 x 2 basket-weave, 13-oz. nylon. The ballistic and physical properties of these laminates were studied in the hope of establishing some correlation between the two properties. Tensile properties of the laminates gave some indication of correlating with the ballistic properties. It was found that polyvinyl chloride bonded laminates possessed ballistic properties equal or superior to those bonded with polymethyl methacrylate and had the advantages of lower resin cost and simplified application. It was noted, furthermore, that the maximum merit factor of bonded laminates prepared in this program was approximately equivalent to that of unlaminated nylon, the latter possessing a value of about 95,000. The temperature and pressure encountered in the molding process were found to have little or no effect on the ballistic properties of unbonded nylon. |
