PREDICTING THE BALLISTIC STRENGTH OF ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE/FIBER COMPOSITES BY IMPLEMENTING FULL FACTORIALEXPERIMENTAL DESIGN
The purpose of the study is to predict the ballistic strength of hard ultra-high molecular weight polyethylene fiber/phenolicballistic composites by implementing the full factorial experimental design. When designing ballistic composites two major factors are the most important: the ballistic strength and the weight of the protection. The ultimate ...

WASTE COPPER USAGE FOR PLANT FUNGICIDE PRODUCTION
Copper Oxyl Chloride 3Cu (OH)2∙CuCl2 is dual salt of copper, chlorine, oxygen and water. It is light green salt without smell. In water and organic solutions it is insoluble while it is easily solluble in acids. It is solluble in ammonia thus building complex units. It is more instable product since it is soluted after longer exposure to air a...
