Edible and biodegradable films have been successfully explored at experimental level, attracting interest in the food preservation and packaging technology fields. However, film technology still presents several challenges for researchers. Namely, there is a lack of systematic information on the relationship between the composition and properties of film forming solutions and the properties of ...

to investigate the effect of tempering treatment on mechanical properties and the microstructure ofdin 1.4021 martensitic stainless steel, austenite treatment was conducted for the samples at 1000ºc temperature for 60 min and then the samples were oil quenched. later, tempering treatments wereperformed for the samples at 500 ºc and 700 ºc temperatures for 2 and 5 h, respectively; then quenching...

the use of agriculture residues as filler in composites is increasing due to their strength, abundance and low cost. soya stalks show promising renewable natural fiber. in polyethylene composites the physical and mechanical properties (flexural resistance, tensile, impacted absorbed energy, water uptake and thickness swelling) was examined at different composites. the results showed that, the m...

Strong beautiful hair is universally desired across various cultures. Hence, the ways in which cleaning conditioning, grooming and styling processes affect the strength, feel and manageability of hair is of interest to beauty care science and technology. Human hair is a complex nanocomposite biological fiber. In this thesis, experiments are performed to better understand mechanical and electric...

This paper describes an experimental investigation of the tensile properties of quartz-silicon dioxide particulate reinforced LM6 aluminium alloy composite. In this experimental, quartzsilicon dioxide particulate reinforced LM6 composite were fabricated by carbon dioxide sand moulding process with variation of the particulate content on percentage of weight. Tensile tests were conducted to dete...

AIM To evaluate the mechanical properties (ultimate tensile strength, elongation and hardness) of the commercially pure titanium (cp Ti) as casting and after ceramic firing cycles. MATERIALS AND METHODS Dumbbell-shaped specimens were prepared for the tensile strength testing. Disk-shaped cast specimens were used for microhardness testing. The ceramic firing cycles were made simulating a low f...

The glycosaminoglycan of decorin, dermatan sulfate (DS), has been suggested to contribute to the mechanical properties of soft connective tissues such as ligaments and tendons. This study investigated the mechanical function of DS in human medial collateral ligaments (MCL) using nondestructive shear and tensile material tests performed before and after targeted removal of DS with chondroitinase...

the enhanced dispersion of organophilic layered silicates improves the mechanical properties of polymer/ silicate composites. in this work, a hybrid filler system consisting of cloisite 15a organoclay (oc) and carbon black (cb) was used to improve the properties of the tire tread compounds. the physical and mechanical properties of compounds were assessed by measurement of their cure properties...

The focus of this study is to investigate the mechanical properties and fracture behaviour of polydimethylsiloxane filled crystalline silica composites (PDMSJCS) via tensile test. The PDMSICS composites were fabricated by using casting method and cured at room temperature for 24 hours. Crystalline silica were filled into PDMS at composition of 2, 6, 10 wt%. The tensile properties of PDMS/2wt%CS...

two different dual phase steels were prepared from low carbon manganese steel after the eliminationof the banding using the direct quenching (dq) and the step quenching (sq) procedures. different heattreatments resulted in different martensite morphologies, microstructures and mechanical properties. theheat treatments were designed in such a way to obtain a 0.25 volume fraction of martensite (v...
