This project was part of a larger research project concerning the use of metallic glass for projectiles. Previous research for that project revealed that the accepted hafnium-copper phase diagram was incorrect. The researchers who researched the incorrect hafnium-copper phase diagram also did research for the zirconium-copper phase diagram so it was suspected… text/html 2013-03-07T19:06:24-04:00 http://dap.cooper.edu/doku.php?id=start:classes:principlesofdesign:jacqueline_le:research:summer_2011&rev=1362701184&do=diff Causes of composite back plate delamination during ballistic impact September 2011-May 2012 During the 2011-2012 school year, I researched whether or not the location of where the projectile strikes a ceramic tile affects the delamination of the composite back plate. Delamination is when the layers of the composite separate apart. The summer of 2011, I researched whether the thickness and area has an affect on back plate delamination. For both research projects, I created targets out of glass… text/html 2013-03-07T18:43:01-04:00 http://dap.cooper.edu/doku.php?id=start:classes:principlesofdesign:jacqueline_le:research:summer_2012&rev=1362699781&do=diff Effect of tile geometry on the ballistic impact of Silicon Carbide Summer 2012 I researched whether or not the size of silicon carbide tiles affects how the tile fractures. For my research, I created targets out of various sized hexagonal silicon carbide tiles, Deerfield Thermoplastic Urethane and polycarbonate. I helped set up and cleaned up the range and the light gas gun that was used to shoot the targets. I also analyzed the damage of the silicon carbide by measuring crack length with…
