“…To ensure the safety of the new constructs, it is necessary to choose allowable stresses and restrict the applied load to a lower value than the construct can fully support ( Casavola et al, 2011 ; Badalassi et al, 2014 ; Deng et al, 2021 ). Considering the inescapable microcracks of the implant and crack growth, allowable stress is a powerful instrument for assessing the implant in terms of strength theory and suitability of the metal material ( Gross and Abel 2001 ; Sarma and Adeli 2005 ; Manral et al, 2020 ). Considering defects in the implant material and the influence of processing technology, greater design load and safe allowable stress should be adopted in the biomechanical assessment of screw failure risk ( Agius et al, 2018 ; Anitua et al, 2018 ; Rahimizadeh et al, 2018 ; Choi et al, 2019 ).…”

In the interests of more flexible and less stiff bridge constructs to stimulate bone healing, the technique of far cortical locking has been designed to improve locked plating constructs in terms of stress concentration, stress shielding, and inhibition of issues around fracture healing. However, far cortical locking screws currently lack objective designs and anti-fatigue designs. This study investigates an optimization algorithm to form a special locking screw composed of various metals, which can theoretically achieve the maintenance of the excellent mechanical properties of far cortical locking constructs in terms of fracture internal fixation, while maintaining the biomechanical safety and fatigue resistance of the structure. The numerical results of our study indicate that the maximum von Mises stress of the optimized construct is less than the allowable stress of the material under each working condition while still achieving sufficient parallel interfragmentary motion. Numerical analysis of high cycle fatigue indicates that the optimized construct increases the safety factor to five. A high cycle fatigue test and defect analysis indicates that the sandwich locking constructs have better fatigue resistance. We conclude that the sandwich locking construct theoretically maintains its biomechanical safety and fatigue resistance while also maintaining excellent mechanical properties for fracture internal fixation.

“…Due to the prominent combination of low shrinkage, dimensional stability, adhesion, dielectric properties, and processing versatility, epoxies are the most common thermosetting polymer for high-performance composites and adhesives [1][2][3]. Furthermore, epoxy has good moisture resistance and is the best material for heavy-duty coatings application due to its superior toughness and hardness values [4,5] Nevertheless, its rigidity, brittleness, and poor resistance to crack propagation limit its applications [6]. Many attempts have been made to improve their physical properties by a variety of methods, including adding nanoparticles to polymer composite [7].…”

The objective of this study is to investigate the effects of different nanoparticles as reinforcement in a polymeric matrix on the mechanical and tribological properties of the composite. The different particles including nanoclay (NC), nano-graphene oxide (NGO), and carbon nanotubes (CNT) with various weight percentages were incorporated into the epoxy matrix. Young’s modulus, ultimate tensile strength, strain at the fracture point, and the fracture toughness of nanocomposite samples were investigated. Besides, the tribological performance of these fabricated nanocomposites was evaluated and discussed. The results show that a significant change in the mechanical properties of the nanocomposites compared to the epoxy matrix. Also, the results reveal that the combination of NC with NGO improves the mechanical properties of graphene nanocomposites. It is found that adding NC to the NG/epoxy composite, may increase the fracture toughness up to 2 times as well as improve the ultimate tensile strength and strain at the fracture point. However, there was no significant change in Young’s modulus.

“…Recent publications on the waste feathers' application for composite materials development report mainly on the combination of waste feathers with synthetic polymers such as polylactide, polyethylene, epoxy-resin, polyurethane, etc. [5,[18][19][20][21][22][23]. In all these investigations synthetic polymers represent one of the main components, and the proportion of waste feathers in composite materials is rather low (below 10%).…”

Preparation and Characterisation of Waste Poultry Feathers Composite Fibreboards

et al. 2020

The growth of poultry meat production is increasing industrial waste quantities every year. Feathers represent a huge part of the waste, and international directives and restrictions prevent landfilling of such biodegradable materials with high burning values. Furthermore, with their unique properties, poultry waste feathers are already a reliable resource for many byproducts, such as keratin extraction, fibres, hydrogel production, etc., all trying to achieve a high-added value. However, mass reduction of waste feathers into useful applications, such as development of alternative building materials, is also an important aspect. To take advantage of feathers’ thermal insulation capabilities, sound damping, and biodegradability, we worked towards mixing waste feathers with wood residues (wood shavings, dust, and mixed residues) for production of composite fibreboards, comparable to the market’s medium density fibreboards. The emphasis was to evaluate waste poultry feathers as the component of natural insulation composites, along with mixed waste wood residues, to improve their mechanical properties. Various composite fibreboards with different shares of wood and feathers were produced and tested for mechanical, thermal, and acoustic properties, and biodegradability, with comparison to typical particle boards on the market. The addition of waste feather fibres into the fibreboards` structure improved thermal insulation properties, and the biodegradability of fibreboards, but decreased their bending strength. The sound transition acoustic loss results of the presented combination fibreboards with added feathers improved at mid and high frequencies. Finally, production costs are estimated based on small scale laboratory experiments of feather processing (cleaning and drying), with the assumption of cost reduction in cases of large industrial application.
