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
This report documents heat release rate measurements of various transient combustibles; that is, non-permanent items found in industrial settings that can potentially contribute to an accidental fire. These items are often included in hypothetical fire

This report contains results of a multi-year experimental program called REBECCA-FIRE (Response Bias of Electrical Cable Coatings at Fire Conditions). Volume 2 of the three volume report focuses on the burning behavior of electrical cables that are
Ten commercial fire-retardant coatings (FRCs) designed for wood in outdoor applications, either film-forming or non-film forming (stains), and five top-coatings (used in combination with a FRC to increase its durability) were characterized by microscale

Polydopamine coatings containing additional bioderived flame retardants were used as coatings for polyurethane foam and cardboard. The ability to form intumescing coatings was crucial for achieving good flame protection. Dopamine can effectively
This study reports on the change in flammability of cotton fabrics caused by water-insoluble gel coatings applied from a single bath solution formulated with polymeric micelles and flame retardant amphiphiles. The flame resistant coatings are made from low

To develop new, efficient flame retardants, it is critical to understand the exact mechanisms by which they inhibit flaming combustion. Our research group has developed a systematic methodology to assess the flammability of polymeric materials through

Pending flammability regulations and scrutinizing of the environment and health consequences of fire retardants is creating opportunities for novel and greener technologies to reduce the flammability of residential furniture. This presentation will

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

A silicone-based elastomer filled with vinyl-silane treated aluminum hydroxide was used as a flame- retardant adhesive for plywood, as a replacement for a conventional polyurethane-based adhesive. The shear strength and fire performance of such a silicone
A kinetic model for 2,3,3,3-tetrafluoropropene (HFO-1234yf) high temperature oxidation and combustion is proposed. It is combined with the GRI-Mech-3.0 model, with the previously developed model for 2-bromo-3,3,3-trifluoropropene (2-BTP), and with the NIST

Reconstructive fire testing is an important tool used by fire investigators to determine the cause, origin, and progression of a particular fire. Accurate reconstruction of the fire requires the laboratory structure to be outfitted with materials that, in

We report a family of flame-retardant electrolytes for lithium batteries based on ionic nanocomposites. The nanocomposites are synthesized in one pot by dispersing SiO2 nanoparticles charge-balanced by both Li ions and mono-amino-terminated polyether (PEO

A mechanism for the combustion of the refrigerant R-32 (CH2F2) in air mixtures was developed and validated through comparisons with measured flame speeds for a range of equivalence ratios (0.9 to 1.4) and pressures (1 to 3 bar) using a constant-volume

In this work, experimental measurements of flame heat flux and sample mass loss rate are obtained as a flame spreads vertically upward over the surface of seven commonly used polymeric materials, two of which are glass reinforced composites. Using these

The components of wood, especially lignin and cellulose, have great potential for improving the properties of polymer composites. In this chapter, we discuss some of the latest developments from our lab on incorporating wood based materials into epoxy
The mass loss rate of Poly(methyl methacrylate) exposed to known radiant fluxes is simulated with two recently-developed numerical codes, the NIST Fire Dynamics Simulator (FDS) and the FAA ThermaKin. The influence of various material properties (thickness
A probabilistic methodology is presented for estimating the building fire losses. This methodology is applied to the specific case of residential upholstered furniture (RUF) fires. The objective of this application is to assess the fire losses associated

A kinetic model for flame inhibition by antimony-halogen compounds in hydrocarbon flames is developed. Thermodynamic data for the relevant species are assembled from the literature, and calculations are performed for a large set of additional species of Sb

Phosphorus-containing compounds are added to polymers as fire retardants, and they are believed to act in both the gas and solid phase. In gaseous flame studies, they have been shown to be very effective gas-phase flame inhibitors; however, their

Certain engineered nanoparticles (ENP) reduce the flammability of components used in soft furnishings (mattresses and upholstered furniture). Most commonly these ENPs are montmorillonite clay (MMTs), multi-walled carbon nanotube (MWCNTs) and carbon
Montmorillonite clay (MMT) is frequently used to create fire resistance in Layer-by-Layer (LbL) applied coatings. This manuscript reports that switching the MMT with layered double hydroxides (LDH) produced a more effective fire resistant coating on
