摘要: Spiders are able to produce different types of silk with mechanical and biological properties. Piriform is produced secure spiders their webs surfaces by using a multi-fibrils system embedded in cement-like matrix. Despite fundamental role, the properties function these anchorages still poorly understood due practical difficulties sample preparation, complexity high variation attachment disc structures. Here we estimated those whole membrane large wandering spider Cupiennius salei through combination nanoindentation nanotensile techniques support simple analytical model. The results highlight piriform silk, facilitating modelling composite mechanics. This could inspire design more efficient bio-inspired adhesives fabrics.
