The use of bio-based materials for production of biocomposites is of interest due to their low cost, abundance and the fact that they are renewable and biodegradable. In this work, an epoxy matrix was produced from residual soybean oil and subsequently used in the preparation of composites reinforced with spent coffee grounds (SCG) fiber. SCG were chemically treated with alkaline hydrogen peroxide...
In this research, first, a method of adhering a minute amount of adhesive, that is, microbonding method of adhesives, has been investigated, and a 2DOF(degree-of-freedom) pantograph mechanism for realizing the microbonding is described. Second, a polymer-made hinge made of polypropylene is proposed, and two kind of 2DOF pantograph mechanisms including polymer-made hinges and links are developed to...
PEEK (poly-ether-ether-ketone) is a semi crystalline thermoplastic with excellent mechanical and chemical resistance properties. In this work the influence of TiO2 nanoparticle at various concentration (0.5, 1 and 1.5 wt. %) on tribological and mechanical properties of PEEK were investigated. The mechanical properties of PEEK Nano composites were studying to evaluate the influence of the nanoparticles...
