Abstract : This project set out to measure, analyze and interpret as well as practically deploy the huge range in mechanical behaviour between different silk species and intra-species varieties. In particular, I set out to formulate a clear-cut link between a silks quality its internal structure and its consequent properties. Here two specific tracks were followed, namely thermal behaviour and melt behaviour. In addition, the uses of different silks in composites with designed properties were examined. The 1st research project (WP1) used thermal analytical methods to truth specific molecular signatures that allow us to differentiate silk qualities. Here thermal analytical methods were used to truth specific molecular signatures that allow us to differentiate silk qualities. For this, DMTA measurements were correlated with changes in molecular and morphological structure resulting from external factors such as diet rearing spinning conditions and storage.
