Life-time Modelling of thermoset Polymers in Structural Engineering
Abstract
Thermoset polymers play an increasingly important role in structural engineering. Compared to classical aerospace or automotive applications the polymers typically do not reach a fully cured state during construction. The material will consequently undergo post-curing during it’s lifetime, changing significantly it’s material characteristics. Currently, the scientific community is lacking modeling concepts for the temperature and curing level dependent mechanical response of set-cast polymers, in particular with regard to visco-elasticity. Due to aging, these materials defy all known concepts for accelerated testing. Hence, the performance prediction for structural life-times of 50 years or longer remains an unsolved challenge. In this proposal an interdisciplinary approach combining experiments and simulations on multiple length and time scales aims at delivering a physically based and thus truly predictive multi-physics multi-scale model for structural applications. The model’s quality will be established by three typical and independent case studies, one classical problem from aerospace and two representative cases in structural engineering.
