      7 - Polymer composites containing sheep wool fibers using thermal and sound insulation: from introduction to application
      Mohsen Sadroddini

      As a natural and environmentally friendly fiber, sheep wool has an extraordinary place among all textile fibers due to its unique properties such as high thermal insulation properties, good sound insulation and absorption, self-extinguishing, high flame resistance, low weight and high strength. Sheep wool fibers are traditionally used in clothing and textiles, but they can be used in various applications. One of the vital industrial applications of sheep wool fibers is to employ them as reinforcing fillers in polymer composites using thermal insulation and sound and acoustic absorbers. This review paper aims to introduce sheep wool fiber and present it as a high-performance fiber (HPF) in the role of a natural and low-cost alternative to synthetic polymer fibers. In this regard, an attempt has been made to conduct a comprehensive review of polymer-sheep wool composites as thermal insulation and sound absorber. Manuscript profile

      Nowadays, in order to treat and repair bone fractures, metal screws and plates are used; But normally, this method will cause problems in surgeries and bone fractures, including skull and vertebral column fractures, which for example can include things such as long operation time which increases the surgery time, the possibility of damage to the bone tissues around the fracture, difficulty and failure. He pointed out the plates. Therefore, researchers and orthopedic surgeons are looking for a suitable alternative to this method. The use of bone glues is one of the new technologies in this direction that has been proposed to solve such problems. These adhesives must have characteristics such as acceptable adhesion of proteins, tissues and bone, especially in the presence of fat around the bone and stability of adhesion in these environments, and over time, have high mechanical strength against tensile, shear and compressive stresses. Also, having characteristics such as non-toxicity, biocompatibility, appropriate biodegradability, quick and easy application, and good fracture stabilization are required for these adhesives. In this article, some of these bio-adhesives, how to prepare and use them are discussed. Nowadays, in order to treat and repair bone fractures, metal screws and plates are used; But normally, this method will cause problems in surgeries and bone fractures, including skull and vertebral column fractures, which for example can include things such as long operation time which increases the surgery time, the possibility of damage to the bone tissues around the fracture, difficulty and failure.
