Natural fibers or natural fibres (see spelling differences) are fibers that are produced by geological processes, or from the bodies of plants or animals. [1] They can be used as a component of composite materials, where the orientation of fibers impacts the properties. [2] Natural fibers can also be matted into sheets to make paper or felt. [3 ...
Lastly, mechanical properties of these biopolymers can often be measured using optical tweezers or atomic force microscopy. Dual-polarization interferometry can be used to measure the conformational changes or self-assembly of these materials when stimulated by pH, temperature, ionic strength or other binding partners.

Hydrogel fiber is a hydrogel made into a fibrous state, where its width is significantly smaller than its length. The hydrogel's specific surface area at fibrous form is larger than that of the bulk hydrogel, and its mechanical properties also changed accordingly. As a result of these changes, hydrogel fiber has a faster matter exchange rate ...
This technique can be useful in creating hydrogels that mimic articular cartilage, enabling a material with three separate zones of distinct mechanical properties. [59] Another emerging technique to optimize hydrogel mechanical properties is by taking advantage of the Hofmeister series. Due to this phenomenon, through the addition of salt ...
The mechanical properties of biodegradable polymers can be enhanced with the addition of fillers or other polymers to make a composite, blend, or copolymer. Some fillers are natural fiber reinforcements such as silk nanofibers, bamboo, jute, in addition to nano-clay, and carbon nanotubes as alternatives to name a few.
Fiber (also spelled fibre in British English; from Latin: fibra) [1] is a natural or artificial substance that is significantly longer than it is wide. [2] Fibers are often used in the manufacture of other materials.
Therefore, their mechanical properties are very important. Mechanical properties of some biomaterials and bone are summarized in Table 1. [2] Among them, hydroxyapatite is most widely studied bioactive and biocompatible material. However, it has lower Young's modulus and fracture toughness with a brittle nature. Hence, it is required to produce ...
Natural fibers are composed by microfibrils of cellulose in a matrix of hemicellulose and lignin. This type of structure and the chemical composition of them is responsible for the mechanical properties that can be observed. Because the natural fibers make hydrogen bonds between the long chains, they have the necessary stiffness and strength.
