Abstract:

The effect of ATC-3 accelerator on the curing time of the epoxy encapsulating the ADAM scatterable mine was investigated by Honeywell, Inc. Curing time was reduced but so were physical properties, which became unacceptably low. Anhydrides, which did not have time to react in the presence of the ATC-3 accelerator and which acted as a plasticizer, are the presumed cause of the low values. The curing effect of ultraviolet radiation on the polyurethane encapsulant for electronics in the GATOR, GEMSS, and RAAM scatterable mines was investigated in-house. Cure time was reduced, but this reduction resulted from heat effect alone. Cure temperatures were far above those allowable, and no photo initiation took place. Mechanical and in situ bonding of the GATOR mine and its styrene aeroballistic section was studied in- house. Such bonding was favorably recommended as a cost-saving production measure, but it will not be used at existing mine production facilities because too much tooling used in common for the GATOR, GEMSS, and RAAM mines would have to be modified.
