The problem of improving the quality of protection against electromagnetic radiation of electronic control units of aircraft is inextricably linked with the level of used materials, which is determined by their functional properties. Such materials can be radio-absorbing dispersed filled polymer composite materials (RADFPCM), to reduce the cost of creating which is relevant to develop a system for predicting the quality of RADFPCM.

The subject of the research is RADFPCM. The purpose of the present research is to develop an algorithm for selecting the optimal composition of RADFPCM. The methodology for conducting the study includes theories of multi-criteria optimization and decision-making. To confirm the basic provisions of the developed algorithm for selecting the optimal composition of RADFPCM, studies were carried out on the example of a polymer composite material based on the rubber of the type SKTN grade A, powder fillers of two types and a PMS-50 (silicone fluid) additive. It is as a result established that for receiving the new filled polymer composite material which is radio-absorbing disperse filled with the value of Shore hardness of 88.88 conventional units, the tensile strength of  Pa, tensile elongation of 54.42% the following structure of components is necessary: silicone SKTN grade A rubber (matrix) - 25%, iron oxide (powder filler) - 38%, aluminum hydroxide (powder filler) - 37%, additive PMS-50 - 0.

The proposed algorithm of selection of the optimal composition of RADFPCM can be applied in the creation of new functional materials for the aerospace industry.

The developed algorithm contains a risk assessment unit according to Savage's criterion, which reduces the risk of approval of the non-optimal composition of the polymer composite material. Thus, even at the stage of computer modeling, a decision can be made on the composition of a new functional material, which reduces the cost of its creation and allows to ensure the required quality, reliability, and safety of the products for which the created materials are intended.
