Conventionally, the development of novel materials is based on numerous experimental and theoretical studies. They are aimed at establishing a correlation between various technological factors and final material properties. It allows one to determine their specific values ensuring the required characteristics. In the case of filled polymer composites, i) properties of phases, ii) their interaction pattern, iii) parameters of technological processes, etc. are taken into account. In general, the number of such control parameters is quite large, which makes the selection of their optimal values quite a complicated problem. On the other hand, many experimental studies are time-consuming and expensive. The paper describes several examples for using the method of visualization of incomplete experimental data. The latter allows to efficiently and clearly analyze and evaluate the effect of various technological factors on material properties, as well as to determine their “optimal” values for developing advanced materials with specified characteristics.
