| Abstract Scope |
Insect cuticle, one of the most common biological composites, has a wide range of its mechanical properties. For example, its elastic modulus covers a range of eight orders of magnitude. Why do cuticle properties vary so dramatically? To address this question, researchers have used different testing methods to measure properties of cuticle specimens, which were selected from various body parts, across a variety of insect species and often preserved/prepared in different ways. However, almost all the factors mentioned earlier can influence obtained data. Hence, here we performed one of the most comprehensive studies, by using one technique to measure the cuticle properties of one species. We simultaneously investigated the microstructure, sclerotization and the elastic modulus of the cuticle in different body parts of desert locust. The results strongly contribute to the current understanding of the relationship between the structure, material property and function in this complex biological composite. |
