Semi-opaque to opaque films containing small amounts of various aluminium particles to decrease emissivity were easily prepared and coated onto low-density polyethylene (LDPE) sheets. The thermal-radiative properties (reflectivity, transmissivity and absorptivity) of the films were measured and related to the aluminum particles' content, size and nature. Time-to-ignition of samples was assessed...

In this paper, burning performance of liquorices was tested by cone calorimeter. The results indicated that liquorices were easily to be ignited, the minimum ignition heat flux intensity theoretically can be speculated at 5.8822kW • m;during the early time of the ignition of liquorices, in view of the thick carbonized layer formed on the surface of samples, which delayed the pyrolysis of liquor...

Many of the photovoltaic (PV) systems on buildings are of sufficiently high voltages, with potential to cause or promote fires. However, research about photovoltaic fires is insufficient. This paper focuses on the flammability and fire hazards of photovoltaic modules. Bench-scale experiments based on polycrystalline silicon PV modules have been conducted using a cone calorimeter. Several parame...

Single-walled carbon nanotube (SWCNT) and multi-walled carbon nanotube (MWCNT) membranes (buckypaper) and carbon nanofiber (CNF) paper were incorporated onto the surface of epoxy carbon fiber composites, as proposed fire shields. Their flammability behaviors were investigated by a cone calorimeter. SWCNT buckypaper and CNF paper did not show notable improvement on fire retardancy. However, MWCN...

The retardancy effect of char formation upon the flammability of thermally thin products is investigated. The char is formed in a single-step non-competitive scheme and is assumed to be thermally stable. The criterion for ignition is that of a critical mass flux of volatiles from the solid into the gas phase. Both steady-state and transient formulations of the model are considered. In the high ...

In order to ensure the safety of inflammable and explosive chemical substance such as nitrocellulose (NC) mixtures in the process of handing, storage, and usage, it is necessary to obtain the fire properties of NC with different exterior structures. In present study, fire properties of two commonly used nitrocelluloses with soft fiber structure and white chip structure were investigated by scan...

A series of flame-retardant nanocomposites were established based on compounding of natural rubber (NR) and dendrimer modified flame-retardant organic montmorillonite (FR-DOMt). The merits of these nanocomposites were focused on their better mechanical and flame-retardant properties. X-ray diffractometer (XRD) together with scanning electron microscopy (SEM) and transmission electron microscopy...

This study investigates the ignition by flaming firebrands of two decking slabs used in French dwellings located Wildland–Urban Interface. The first slab was made pine and second one a thermoplastic composed polypropylene calcium carbonate. Flaming were produced heating igniting wood chips different shapes (square, longitudinal rectangular) with cone calorimeter. generated preserved their shape...

Abstract The fire behaviour of electric vehicles (EVs) differs from that with combustion engines. Especially the rechargeable energy storage system (REESS) requires special protection measures. materials for REESS housings plays an important role in resistance such systems. Full-scale tests like gasoline pool on complete according to UNECE-R100-8E standard are mandatory EVs. However, these not ...

The purpose of this study was to provide insights into deeper understanding the combustion performance cement-bonded particleboards. Cement-bonded particleboard produced from Chinese fir processing residues is fabricated and its further evaluated by cone calorimeter analysis. Obtained results revealed that positively depends on density which, higher imparts corresponding particleboards reductio...
