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 ...
Cotton is a natural fiber (纤维) from the cotton plant. It is one of the oldest fibers used by human being, with a planting history over 7,000 years. This plant produces lovely flowers. The cotton fiber forms around the seeds of the plant and helps carry the seeds long distances on ...
(nature) protein fiber and some forms of silk together with other fabrics can be weaved into textiles(纺织物). China is said to be the first country in the world(2) to have master(master) the sericulture technology(养蚕技术) to produce raw material of silk cloth....

Natural fiber, hairlike material directly obtained from an animal, vegetable, or mineral source and convertible into nonwoven fabrics such as felt or paper or, after spinning into yarns, woven cloth. Nature abounds in fibrous materials, such as cotton, w
The performance of natural fiber-reinforced polymer composites depends on several factors, including the chemical composition, cell dimensions, microfibrillar angle, defects, structure, physical and mechanical properties of the fiber, and also the interaction of the fiber with the polymer [15].

carbon fiber technology converts the carbon to graphite, which forms long, thin ribbons that pack together to form fibers. Carbon fibers show promise as components of composites for aircraft and autos, but the added expense has limited carbon fiber technology to production of high-quality devices ...
