Recently, a research group at Bolton Institute has developed a ‘Responsive Heat Barrier Material’, showing performance equivalent to commercial barrier materials.1,2 This material is composed of non‐woven flame‐resistant fibres and a dispersed intumescent. When exposed to fire or very high temperatures, both these components char by physically and chemically compatible mechanisms, forming a char‐bonded structure, which has high mechanical properties and is resistant to oxidation. These materials have potential uses in transport upholstery, protective clothing and as firewalls in car bodies between the engine and passenger compartments. The main objective of the research presented here was to carry out multivariate analysis upon data from the experimental work carried out to date. The results from this analysis will enable the production of formulae which can be used to predict the performance of ‘responsive heat barrier materials’. Further materials will then be produced, tested and compared with the predictive models in order to ascertain the validity and accuracy of the formulae derived from the present work. © 2000 Society of Chemical Industry
