... Abstract This article describes the basic approaches to improving the fire resistance of a polymeric material, considers the burning process on a microscale and macroscale, and discusses various test methods for determining the flammability characteristics of polymeric materials. Test methods...

... of the screws. Background In an aircraft engine under development, during cyclic spin tests on an LP turbine disc, a loud noise was heard when the turbine speed had reached around 12,000 rpm. This noise was followed by a fire. The drive motor was shut immediately and the fire extinguished. On strip...

Since they contain a large proportion of aromatic structures, phenolic resins carbonize in a fire and self-extinguish once...

Oil quenching still has use in small production lots where polymer-based quenching testing is not feasible but the prevention of quench cracks and minimized distortion are important. Polymer-water...

Unfilled polyamide (nylon) typically is self-extinguishing on some flammability tests because the portion that burns also melts, and the flaming portion drops away, leaving an extinguished remainder. However, with the addition of glass fiber, the ignited sample...
