Abstract
The article describes a special installation allowing real-time determination of the pressure drops within the impregnation process. The installation working zone is a flat permeameter, where the reinforcing material under study is laid, and liquid is supplied. Ultra-low pressure membrane sensors were used to register pressures along the fluid motion direction. Diagram of the sensors installation is provided, as well as substantiation of selecting a site positioned between two adjacent sensors, where it is advisable to conduct the experimental research. Based on the data obtained, the permeability values coefficients were calculated. The article presents results of assessing the accuracy of the proposed method to determine the permeability coefficient values, which was obtained by the authors in comparing experimental and theoretical duration of the impregnation process.
