Development of film- and- fabric composite materials durability assessing methodology under time-dependent influences of temperature and solar radiation

摘要

In this paper, we present the design of stress-strain state calculation and film-and-fabric composite materials durability under stresses and solar radiation. We have constructed a two-dimensional fmite-state-element computer model of the deforming process of the low-level cell of fdm-and-fabric-based composite material for the evaluation of its durability which takes into account non-linear viscoelasticity, temperature variations, ageing of the material, the process of upbuilding of microdamage and photodegradation. Qualitative research of operational factors influence (UV, temperature) on film-and-fabric composite materials durability was conducted.
