Abstract:

The performance under ballistic impact conditions of a nylon 6-based polymer-layered silicate PLS nanocomposite was examined using a V50 test. The commercially available nanocomposites contained approximately 2.5-wt. montmorillonite clay mineral and were fabricated by in situ polymerization of epsilon-caprolactam in the presence of an organosilicate clay mineral. The velocity at which 50 of 0.22-cal. fragment simulator projectiles penetrated the unmodified nylon 6 and 0.5-mm aluminum witness plate V50 was determined to be 436 fts. The PLS nanocomposite nylon 6-clay hybrid was found to have a V50 of 338 fts. Therefore, it was found that the addition of the layered silicate clay mineral filler did not improve the impact properties of nylon 6 under these conditions.
