Author(s)
Mauro Zammarano, John R. Shields, Isaac T. Leventon, Ickchan Kim, Shonali Nazare, Andre L. Thompson, Rick D. Davis, Artur A. Chernovsky, Matthew F. Bundy
In this work, we describe a reduced-scale test (“Cube” test), based on cone calorimetry, measuring the fire performance (heat release rate, propensity to pool-fire formation, etc.) of composite specimens including a fire barrier (FB) and a flammable core

Assessing Fire-blocking Effectiveness of Barrier Fabrics in the Cone Calorimeter

April 29, 2019
Author(s)
Shonali Nazare, William M. Pitts, Mauro Zammarano, John R. Shields, Elizabeth Knowlton, Benito De Leon
Cone calorimetric experiments have been conducted on bare flexible polyurethane foam (FPUF) samples as well as FPUF covered with a variety of fire-blocking barrier fabrics (BFs) in order to characterize and rank BF effectiveness for improving the

Smoldering and Flame Resistant Textiles via Conformal Barrier Formation

November 2, 2016
Author(s)
Mauro Zammarano, Shonali Nazare, John R. Shields, Kathleen M. Hoffman, Rick D. Davis
A durable and flexible silicone-based backcoating (halogen and formaldehyde free) is applied to the backside of an otherwise smoldering-prone and flammable fabric. When exposed to fire, cyclic siloxanes (produced by thermal decomposition of the backcoating
