“…In engineering, energy absorption and dissipation are mostly used for characterizing the ability of resistance to failure and fracture of materials. − Although for biomaterials such as bone, which is a complex hierarchically organized material consisting of cells, mineral, and collagen, the energy absorption/dissipation ability functioned to provide the material with typical mechanical resistance property . Compared to the bony material, the PDL has much more fibrillar collagens, resulting in significant shock resistance ability during mastication force transmitting.…”

As a layer of soft fibrous tissue, the periodontal ligament (PDL) protects against mechanical shock when transmitting mastication force from tooth to its surrounding alveolar bone. Currently, no quantitative method is available to estimate the shock resistance ability of the PDL. To solve this problem, in the present study we developed a finite element (FE) model of the tooth-PDL-bone complex and analyzed the energy storage and dissipation during the mastication movements. Displacement and Mises stress of tooth-PDL-bone complex show that the PDL is able to protect the alveolar bone from mechanical shock by shielding the transfer of deformation and stress. During mastication, the energy of the PDL is stored up to ∼161.5 J/mm3 at the period of loading and dissipated about one-tenth of the stored energy when unloading. The energy storage is displacement-dependent but time-independent because of the hyperelasticity of PDL. However, the energy dissipation is time- and displacement-dependent because of the viscoelasticity of PDL. The present study helps to understand the periodontal potential and the origin of dental diseases such as tooth concussion and occlusal trauma from the view of energy conversion.

“…Since the pores will get impregnated by the resin matrix, the actual volume occupied by the nanofiber interleaves is very small and further shrinkage happens while pressure is applied for laminate consolidation. In order to overcome the low porosity of film interleaves, perforated film interleaves have also been used …”

Fiber-reinforced polymer composites find extensive applications ranging from sporting goods to aircraft components. Nonetheless, the weak interlaminar properties of laminated composites impose challenges in the design of primary load-bearing structures. The incorporation of additives (e.g., particles, films, and fibers) can overcome these limitations, offering additional functionalities to composites. Interleaving in composites generally refers to the incorporation of materials at the interface between two fiber plies so as to improve various properties. Being a simple technique to integrate in the production line, interleaving is recognized as an industrially significant and commercially viable method of modifying laminated composites. In this Review, an effort to assess state-of-the-art research on interleaving is attempted. Methods, applications, and the influence of interleaves on various properties of composites are also discussed. Data from the most recent research works on interleaved composites are compiled in an attempt to aid and encourage further developments among industries and academia.

“…Introducing a weak plane may be achieved by inclusion of a polytetrafluoroethelene (PTFE) slip foil, a common technique for initiation of cracks in delamination experiments. To reduce the severity of a complete disbond, the PTFE foil may be perforated, so as to maintain a certain amount of interlaminar strength; as demonstrated by Kuhtz et al [7] However, any physical barrier (with or without perforations) will hinder the formation of fibre bridg- ing. It is shown that fibre bridging is a toughening mechanism which is useful for reducing crack growth.…”

Sized glass fibre bundles were treated using atmospheric pressure plasma in a helium/ tetrafluoromethane gas mixture. X-ray photoelectron spectroscopy showed that fluorine was introduced onto the sizing surface. A new analysis method (dynamic micro-wetting) to determine the wetting rate of the plasma treated fibre bundles is presented. The dynamic micro-wetting test using glycerol as a test liquid showed a reduced wetting rate after plasma treatment. It is demonstrated that dynamic micro-wetting is a useful tool for characterization of fibre bundle wetting.
