Analysis of the correlation of changes in mechanical and diffusion characteristics of fiberglass VPS-53/T-25 during full-scale and accelerated climatic tests

V.O. Startsev, A.A. Nechaev
Abstract

Climatic testing of VPS-53/T-25 fiberglass was conducted in outdoor, moderate and moderately warm climates for 12 months, as well as laboratory simulation tests in two modes. After all intermediate measurements, flexural strengths were measured, taking into account the reversible effect of moisture. The mass of the specimens was measured during drying and wetting to determine moisture transfer parameters. Correlations between the studied characteristics were calculated during full-scale and accelerated climatic tests.
