| Abstract Scope |
The recluse spider is the only of >45,000 spider species known to make a ribbon shaped fiber featuring a high aspect ratio. It is also the only species known to feature an external spinneret capable of spinning its self-adhesive silk tape into a 1-dimensional metastructure giving rise to novel mechanical characteristics. The adhesive junctions of this structure feature a surprisingly high strength. Our experiments with synthetic adhesive tapes have revealed that this is based on an unexpected effect, which only occurs in a narrow window of junction angles, which is precisely implemented by the spiders. The mechanism can be exploited for sticky tape metamaterials with surprising mechanical properties. |
