Durability of Polymer Based Composite Systems for Structural Applications.Analysis and Predictions

摘要

Most of the new composite systems, based on polymers (materials, structures andadhesive joints) exhibit time effects and their behaviour is strongly influenced by temperature moisture absorption and other environmental factors. The use of these materials for structural applications, mechanical loads, (of static, dynamical amd impact type), in a surrounding with varying environmental conditions, needs design procedures, which take into account this general loading history interacting with the thermomechanical characteristics, in order to obtain a reliable prediction of the long term behaviour. A valid methodology for life time prediction and/or durability analysis is probably the key element for a larger development of the use of polymer based composite systems in structures in the future.
