Statistical Regularities of Forming Porosity in Plane-Parallel Basalt-Plastic Composite Materials during Climatic Degradation and Forecasting Their Properties

Statistical regularities of porosity formation during climatic tests of plane-parallel composite materials are revealed. To predict changes in the physical and mechanical properties of composite materials, it is proposed to use the Balshin–Huttig relationship of dimensionless properties and porosity. Taking into account experimental data on the porosity of plane-parallel basalt-plastic and fiberglass composite materials, calculations are made to reduce their physical and mechanical properties.
