Abstract

Mechanical properties of glass and carbon reinforced plastics were investigated after natural weathering in mild warm climate. The seasonal changes in mechanical properties of PCMs were found to be in agreement with moisture content in the samples. The difference in compressive and bending strength of VKU-49 carbon fiber reinforced plastic, measured in winter and summer month reached 10%. It was shown that for evaluation of reversible influence of moisture during the natural weathering measurements of the mechanical properties of PCM should be measured in three states: without conditioning, after drying and after moisture absorption till the steady state.
