Bioinspired adhesive and computational design of interfacial materials

摘要

The structural and mechanical lessons gained by investigating the byssus network could provide us with important design principles that can be applied in the fabrication of interfacial materials that can function effectively under dynamic loadings. We have found that the use of about 20% soft material in mussel threads is crucial in light of impact absorption and force reduction for the entire animal. This principle reflects the finding that the greatest force deduction comes from the soft material, which makes up only a small portion of the overall thread. We have shown that precise 3D printing provides an avenue to generate fast prototype samples according to computational design. The trends of the mechanical performance of printed samples are in well agreement with simulations. Our result demonstrated that by controlling the curing time and the dynamics of two material phases for mixing, we can program and improve the mechanics of the composite structure.
