Polymer nanocomposites have tremendous potential to enhance the performance of macromolecular materials used for composite matrices, but an important issue that needs to be addressed is ageing behaviour. This paper focuses on recent research and development in the area of ageing and performance predictions of polymer nanocomposites that are applied in defence and aerospace industry. During ageing, photo-degradation, biodegradation, thermo-mechanical degradation and thermo-oxidative decomposition, reactions often run simultaneously in a heterogeneous environment, changing the structure and phase distribution of polymer nanocomposites. Since experimental data on the single decomposition processes are often not available, computer-aided chemistry approach often provides new insights into the ageing mechanisms. Studies on ageing and performance predictions of polymer nanocomposites are an important task that helps to understand the ageing behaviour and to predict nanocomposite's behaviour in an extrapolated time or temperature conditions.
