A fabric filler in pressure impregnation
The behaviour of a glass-fiber material under loading is investigated and dependences of change of porosity and a degree of filling on pressure of condensation are received. It is shown, that at pressure of condensation 0,6 МPа porosity accepts the minimal value and at the further increase in effort of compression practically does not change. On physical model process of current of a liquid in porous space is researched. It is shown, that factors of permeability of system do not remain constants and depend on such factors as a direction of current (a basis, ducks), time of current, a degree of filling, pressure of submission and viscosity of a liquid. The received values of factors of permeability of system can be used at mathematical modelling current of the liquid environment through porous space in calculations of time of impregnation of a glass-fiber material for real designs.
