Abstract

The surface topography of VPS-53/T-25 fiberglass was studied after 24 months of outdoor climatic testing in moderate and moderately warm climates, as well as after laboratory simulation tests in two modes. After each exposure, the surface topography characteristics of the samples were analyzed, plotting the distribution of surface irregularity heights. Significant differences in the rate of change in the centers of the surface irregularity distribution were revealed during both full-scale and accelerated laboratory climatic tests.
