in this study , the physical and mechanical properties of polypropylene composites reinforced with bagasse alkaline-sulfite-anthraquinone, soda-anthraqouinone, monoethanolamine-anthraquinone chemical pulps and mechanical pulp (cmp) known as pulp-plastic compostes (ppc) were investigated and the results were compared among ppcs and with polypropylene composites reinforced with bagasse flour know...

Glass fiber reinforced polymer composites are one of the most widely used composite materials. The addition of Coal ash to polymer matrix dramatically increases the overall mechanical strength of the composite material as compared to the polymer composite. In view of this, a method is proposed for mixing coal ash powder (size 52-75 μm) into resin and Ash reinforced polymer composites are fabric...

One of the key issues associated with using of composites in various applications is their tensile behavior. The tensile behavior of a composite material is strongly influenced by the properties of its constituents and their distribution. This paper focuses on gaining some insights into the tensile process of pure and hybrid woven composite reinforced with brittle and ductile yarns. For this pu...

Paper/polyacrylic acid (PAA) composites were prepared using a microcrystalline cellulose (MCC)-reinforced PAA hydrogel. The MCC-reinforced PAA hydrogel was prepared by in-situ UV light-induced polymerization of acrylic acid in the presence of MCC. The experimental results showed that the presence of MCC improved the water absorption capacity of the resulting PAA hydrogel. The addition of 1 wt% ...

The purpose of the study is to utilize the chicken feather and finding the mechanical properties of the chicken feather reinforcing with polyester and phenyl ester. The bi-directional CFF reinforced composites were produced with phenyl ester and polyester resins with fiber reinforced composites, the chicken feather fibers (CFF) were cleaned, tested to know the mechanical properties and tensile ...

The glass fiber reinforced epoxy resin composites play an important role in superconducting Tokamak, which are used to insulate the metal components, such as superconducting winding, cooling pipes, metal electrodes and so on. For the components made of metal and glass fiber reinforced epoxy resin composites, thermal shrinkage leads to non-ignorable thermal stress, therefore, much attention shou...

The TiCp/Cu master alloy was prepared via thermal explosion reaction. Afterwards, the nano-sized TiCp/Cu master alloy was dispersed by electromagnetic stirring casting into the melting Cu-Cr-Zr alloys to fabricate the nano-sized TiCp-reinforced Cu-Cr-Zr composites. Results show that nano-sized TiCp can effectively refine the grain size of Cu-Cr-Zr alloys. The morphologies of grain in Cu-Cr-Zr c...

Synthetic hydroxyapatite (HA) whiskers have been utilized as a new, biocompatible reinforcement for orthopedic biomaterials. High-density polyethylene (HDPE) was reinforced with either the synthesized HA whiskers or a commercially available spherical HA powder using a novel powder processing technique that facilitated uniform dispersion of the reinforcements in the matrix prior to compression m...

Short banana fiber reinforced composites have been prepared in laboratory to determine mechanical properties. It has been observed that as soon as the percentage of the banana fiber increases slightly there is a tremendous increase in ultimate tensile strength, % of strain and young modulus of elasticity. Reinforcement of banana fibers in epoxy resin increases stiffness and decreases damping pr...

Fiber-reinforced laminated composites are frequently preferred in many engineering projects. With the development in production technology, the using of the fiber reinforced laminated composites has been increasing in engineering applications. In the production stage of the fiber-reinforced laminated composites, porosities could be occurred due to production or technical errors. After a level o...
