From a set of around 30 thermosets (polycyanurates, polybenzoxazines, epoxy and phtalonitrile resins) tested in pyrolysis-combustion flow calorimetry, the contributions to flammability of 14 new chemical groups are calculated using a method previously proposed and validated. The flammability properties include total heat release, heat release capacity and char content. The comparison between these...
A new method is proposed to calculate the flammability of polymers from their chemical structure using a Van Krevelen approach. The model is inspired from a pioneering work of Lyon which assigns one flammability contribution to each chemical group. The flammability property of the whole polymer is the sum of the contributions of chemical groups constituting the polymer. Two intrinsic properties (namely...
