Spider silks mechanics: Predicting humidity and temperature effects

نویسندگان

چکیده

We deduce a microstructure inspired model for humidity and temperature effects on the mechanical response of spider silks, modeled as composite material with hard crystalline soft amorphous region. Water molecules decrease percentage crosslinks in softer region inducing variation natural length macromolecules. The resulting kinematic incompatibility between regions crucially influences final response. demonstrate predictivity by quantitatively reproducing experimentally observed behavior.

Multiscale mechanisms of nutritionally induced property variation in spider silks

Variability in spider major ampullate (MA) silk properties at different scales has proven difficult to determine and remains an obstacle to the development of synthetic fibers mimicking MA silk performance. A multitude of techniques may be used to measure multiscale aspects of silk properties. Here we fed five species of Araneoid spider solutions that either contained protein or were protein de...

Recombinant Spider Silks—Biopolymers with Potential for Future Applications

Nature has evolved a range of materials that compete with man-made materials in physical properties; one of these is spider silk. Silk is a fibrous material that exhibits extremely high strength and toughness with regard to its low density. In this review we discuss the molecular structure of spider silk and how this understanding has allowed the development of recombinant silk proteins that mi...
