Objective(s): Scaffolds are considered as biological substitutes in bone defects which improve and accelerate the healing process of surrounding tissue. In recent years a major challenge in biomaterials is to produce porous materials with properties similar to bone tissue. In this study, the natural bioactive hydroxyapatite scaffolds with nano Diopside /Forstrite coating was successfully synthe...

The effect of thermal cycling treatments on the thermal stability and mechanical properties of a Ti48Zr20Nb12Cu5Be15 bulk metallic glass composite (BMGC) has been investigated. Results show that moderate thermal cycles in a temperature range of −196 ◦C (cryogenic temperature, CT) to 25 ◦C (room temperature, RT) or annealing time at CT has not induced obvious changes of thermal stability and the...

Recently, there has been a fast growth in research and investigation in the natural fibre composite due to the advantages of these materials, such us low environmental impact, low cost and good mechanical properties compared to synthetic fibre composites. Much effort has gone into increasing the mechanical performance and applications of natural fibes. This paper examines the mechanical propert...

Background and Objectives: Kefiran (Kef) is a water-soluble polysaccharide that can form transparent film however, it is brittle. Therefore, in order to improve the mechanical properties of kefiran film, a mixture with other polymers can be offered. The expansion of mixed systems can propose kefiran and polyvinyl alcohol (PVOH) as a new composite film. Materials and Methods: Solutions of 20 gr...

Natural fibers have recently become attractive to automotive industry as an alternative reinforcement for glass fiber reinforced thermoplastics. The best way to increase the fuel efficiency without sacrificing safety is to employ fiber reinforced composite materials in the body of the cars so that weight reduction can be achieved. Designing the structures with the focus on improvement aspects i...

The application of nanoparticles in order to enhance the composites properties has been recently attracted many researchers' attentions. To increase the mechanical and physical properties of the composites, the nanoparticles have no significant effect on the weight and nanostructure of composites. One of the well-known nanoparticles is the Nanoclay (NC) that have been widely used in industries ...

utilization of the new compatibilizers to improve matrix/filler interface adhesion and also, nanoparticles to improve the properties of wpc products have always been of interest to researchers. in this study, the effect of oxidized polypropylene in solution phase as a comptibilizer and nanoclay particles on the physical and mechanical properties of wood fiber reinforced polypropylene composite ...
