When a mollusk shell has more than one macro-layer, the crossed-lamellar structure exhibits various forms of architectures including 0°/90°, 0°/90°/0° typical-sandwich, 15°/75°/0° quasi-sandwich, and 0°/90°/0°/90° arranged modes. The fracture resistance and the relevant ...

The cuticle consisting of a scale structure over the surface can provide the basis of felting in wool and hydrophobic property to repel liquid water [35]. The cortex of wool forms approximately 90% of the fiber. Cortical cells in the cortex are polyhedral, spindle-shaped, and around 100 ...
Define Natural Fiber/Natural Fiber-based. means a plant or animal-based, non-synthetic fiber, including but not limited to products made from paper, sugarcane, bamboo, wheat stems/stalk, hay, wood, etc.
of active materials. Moreover, substrates made of β-sheet crystallites offer outstanding mechanical strength. Here, we review synthesis and applications of modified silk in energy and sensing. The three ways to modify silk are: before the fiber is spun by the worm, i.e. in-vivo, after it...
The crystalline sections consists mainly of heavy molecular chains (H-chain)24, which in turn, are primarily GAGAGS-repeats25. The H-chain exists in four forms: amor- phous random-coil conformation and three semi-crystalline forms, labeled silk I, silk II3, and silk III26. Marsh, Corey ...
Natural fiber is an environmentally-friendly product that is widely used in textiles and other industries. It is widely used in yarn and fabric forms in the textile sector. Natural fiber is also employed in other applications such as automobiles, boards, and construction of individual or blended ...
It is thought that fiber is well distributed in the CA composite and that the fiber-matrix could bear the load resulting in an increase of FS. This consideration can be well explained from the SEM picture that shows fiber forms a domain in the EVA composite or coagulation of fiber, as a...
The paper reviews the properties of cement composites reinforced with short fibres. The effect of natural fibres was investigated: cotton, sisal, jute, ramie, bamboo, and synthetic fibres: polymer and polypropylene. It was noticed that the fibres change
