31. Chemical and Physical Characterization of Poly(p-phenylene-2,6-benzobisoxazole) Fibers Used in Body Armor: Temperature and Humidity Aging
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7373
Published: 11/1/2006
Authors: Joannie W Chin, E Byrd, Cyril Clerici, Amanda Lattam Forster, M Oudina, Li Piin Sung, Kirk D Rice
Abstract: In recent years, poly(p-phenylene-2,6-benzobisoxazole) (PBO) fibers have become prominent in high strength applications such as body armor, ropes and cables, and recreational equipment. The objectives of this study were to expose woven PBO body arm ...

32. Mechanical Properties of Nanocomposite Latex Films via Instrumented Indentation
Published: 9/6/2006
Authors: Aaron M Forster, Stephanie S Watson, Laura Johnson, Li Piin Sung
Abstract: Inorganic particles, introduced into networked or glassy polymer films, have been used to increase the stiffness of films as a function of pigment loading. Latex films often contain inorganic pigments to increase the opaqueness of the film and to ac ...

33. Load-Displacement Relations for Nanoindentation of Viscoelastic Materials
Published: 8/2/2006
Authors: Chien-Kuo Liu, S H Lee, Li Piin Sung, Tinh Nguyen
Abstract: A model based on the Burgers viscoelastic concept has been developed to describe the nanoindentation behaviors of polymeric materials. An analytical solution of displacement at the indenter tip has been derived based on the analog of the governing eq ...

34. Chemical and Physical Characterization of Poly(p-phenylene benzobisoxazole) Fibers Used in Body Armor
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7237
Published: 5/1/2006
Authors: Joannie W Chin, E Byrd, Amanda Lattam Forster, Xiaohong Gu, Tinh Nguyen, Kirk D Rice, Walter J. Rossiter Jr, S J Scierka, John R Sieber, Paul E Stutzman, Li Piin Sung
Abstract: Problems with the performance and durability of body armor based on poly(p-phenylene benzobisoxazole (PBO) fiber became apparent in the summer of 2003, when PBO-based body armor that was less than 8 months was penetrated by a bullet. Mechanical te ...
