“…Within the entire R&D cycle, DoE processes make closed sub-cycles (each one closes by the link from interpretation to the first stage). Methods of single-and multivariate [30] optimization (search for local and global extrema, clustering and so on) are usually applied during interpretation of experimental results. Multivariate techniques consider several random variables as a single entity and produce overall result in form of smaller set of uncorrelated variables or even single variable [31].…”

Thermoset-based polymer matrix composites are widely used for production of intumescent fire protective coatings; many operational properties of such coatings can be further enhanced by means of nanoscale layers between matrix and disperse phases. The dependence between temperature of processing and temperature of glass transition of thermosetting matrix allows to produce gradient of glass transition temperature along the depth of the coating and lower exfoilation of char residue from steel substrate. In the present article we have offered the novel design scheme for such coating. Several results of laboratory and numerical experiments that are within the framework of the offered scheme are also presented. Application of the offered scheme allows to develop efficient fire protective coatings in purposely and precisely controlled manner.

“…This level is formed when binder is combined with fine filler (specific surface of such filler is usually above 100 m 2 /kg; corresponding particle size is below 10 um). Numerous processes take place during hardening of microstructure; cluster formation [8,9] is one of such processes.…”

Abstract. Classic R&D in material science was based on statistical modeling. However, large number of control factors and the absence of universal computational method that can be used for numerical investigation at all structural levels of constructional composite dictate the necessity of multiscale approach in computational material science. In the present work we are focusing on the description of spatial scales and primary types of interactions that take place in different layers of building materials. The five spatial scales are considered. Three of them allow using the simplest and universal modeling method that is based on the representation of composite as a particle system; still, modeling requires taking into account some extra types of pair forces and forces that are arising due to technological actions.
