The Mechanical Properties of Individual Electrospun Fibers and Fibrin Fibers
Nanofibers play important mechanical roles in the body. Collagen, the most abundant protein in humans, forms fibers which comprise part of the extracellular matrix and tissues such as bone, cartilage and blood vessels, to name a few. Fibrinogen, a plasma protein, is converted into fibrin fibers …

Strength-structure relationships in carbon fibers
The three-dimensional microstructure and macrostructure of various PAN-based carbon fibres has been characterized by bright- and dark-field transmission electron microscopy, and quantitative electron-diffraction analysis. A skin-core heterogeneity was observed for all fibres heat treated to 2500°C, …
