Abstract
To study the influence of synthesis parameters on the properties of porous glass-composite materials, statistical methods of experiment planning were used, which make it possible to optimize the technology and reduce labor and energy costs. A planning matrix has been developed for conducting a fractional factorial experiment. Coded and non-coded regression equations, histograms of the frequency of free residuals, Pareto diagrams, a model of predictive distribution of values according to the normal distribution law, dispersion models of indicator values, a matrix of the relationship of independent variables and the resulting density value were obtained and analyzed. It has been established that the most significant factor affecting the density is the amount of blowing agent.
Keywords: mathematical statistics, mathematical modeling, synthesis of porous glass composites, porous glass composite materials, properties of porous glass composites
