Thermal and Flammability Properties of a Silica-Poly(methylmethacrylate) Nanocomposite

January 1, 2003
Author(s)
Takashi Kashiwagi, A B. Morgan, Joseph M. Antonucci, Mark R. VanLandingham, Richard H. Harris Jr., W H. Awad, John R. Shields
MMA, poly(metheylmethacrylate), nanocomposites were made by in situ radical polymerization of MMA, methylmethacrylate, with colloidal silica (ca. 12 nm) to study the effects of nanoscale silica particles on the physical properties and flammability

TROPODEGRADABLE AND OTHER ENVIRONMENTALLY ACCEPTABLE FLAME EXTINGUISHANTS

January 1, 2003
Author(s)
J D. Mather, R E. Tapscott
In work sponsored by the National Institute of Standards and Technology and the Next-Generation Fire Suppression Technology Program, our current research effort is directed toward the continued study of known promising as well as several new chemical

Estimating Temperatures in Compartment Fires

December 31, 2002
Author(s)
William D. Walton, Phillip H. Thomas
The ability to predict temperattures developed in compartment fires is of great significance to the fire protection professional. There are many uses for the knowledge of compartment fire temperatures, including the prediction of (1) the onset of hazardous

Advances in Materials and Mechanics

December 1, 2002
Author(s)
K P. Chong, Mark R. VanLandingham, Li Piin Sung
Mechanics and materials are essential elements in all of the transcendent technologies that are the primary drivers of the twenty first century and in the new economy. The transcendent technologies include nanotechnology, microelectronics, information

Database-Assisted Wind Load Capacity Estimates for Low-Rise Steel Frames

December 1, 2002
Author(s)
S Jang, L L. Lu, Fahim H. Sadek, Emil Simiu
A comparative study is presented of the estimated wind load capacities of low-rise steel building frames based on loading patterns (magnitude and distribution) established from aerodynamic databases on the one hand, and on patterns specified in the ASCE 7

Effect of Wind Velocity on Flame Spread in Microgravity

December 1, 2002
Author(s)
Kuldeep R. Prasad, S L. Olson, Y N. Nakamura, K K. Nishizawa, K. Ito, Takashi Kashiwagi
A three-dimensional, time-dependent model is developed describing ignition and subsequent transition to flame spread over a thermally thin cellulosic sheet heated by external radiation in a microgravity environment. A low Mach number approximation to the

Extinction of Cup-Burner Diffusion Flames by Catalytic and Inert Inhibitors

December 1, 2002
Author(s)
Gregory T. Linteris
The first tests of super-effective flame inhibitors blended with CO2 have been performed in methane-air co-flow diffusion flames. Although the organometallic agents used are typically one or two orders of magnitude more effective inhibitors than CF3Br when
