Thermal and Mechanical Response of POSS coated Nanophased expandable foam core materials

Jones W.D., Rangari V.K., Jeelani S., Tuskegee University, US

A sonochemical technique has been established to coat variations of POSS nanoparticles on expandable microspheres. Thermal analyses results indicate that there is an increase in thermal stability of nanophased foam as compared to the neat [...]

In-situ synthesis of Cu nanoparticles on MWCNTS using Microwave irradiation

Rangari V.K., Dey S., Jeelani S., Tuskegee University, US

Microwave irradiation technique is successfully used to synthesize the copper coated MWCNTS in a one-pot reaction with and without surfactant. Since the graphite carbon absorbs the (in 2min 1100oC) maximum microwave radiation had led to [...]

Sonochemical Coating of TiC nanoparticles on expandable polymeric microspheres, Thermal & Mechanical properties of microspheres/epoxy nanocomposites

Rangari V.K., Hassan T.A., Mayo T. Watson Q., Jeelani S., Tuskegee University, US

Summary • Sonochemical method has been developed to coat nanoparticles on expandable polymeric microspheres. • n-Hexane is used as a solvent and proved to be a suitable solvent for sonochemical coating of nanoparticles on these [...]

Processing and Characterization of Epon 862 reinforced with functionalized MWCNT’s

Theodore M., Hosur M.V., Thomas J., Jeelani S., Tusekgee University, US

In the current research work, functionalization of pristine MWCNTs was performed by oxidation in acid solution (MWCNT-COOH), direct-fluorination (MWCNT-F), and amino-functionalization (MWCNT-NH2). An epoxy-nanocomposite material was developed through the use of functionalized Multi-wall Carbon Nanotubes [...]

Effect of particle size on the mechanical properties of polymer matrix nanocomposite

Zhou Y.X., White E.T, Jeelani S., Tuskegee University, US

In the present investigation, we have studied effect of inclusions size on mechanical properties of nanocomposite materials containing SC-15 epoxy resin and TiO2 particles. Micro sized particles have little effect on modulus and strength of [...]

Synthesis of Shear Thickening Fluid Using Sonochemical Method

Rangari V.K., Hassan T.A., Mahfuz H., Jeelani S., Tuskegee University, US

Shear thickening fluid is developed using sonochemical method which one step process and can be processed from its dry metal oxide powder forms instead of its colloidal solution. The main problem with the current process [...]

Improvements in High Specific Strength Epoxy-Based Composites using High Magnetic Fields

Mahfuz H., Zainuddin S., Rangari V.K., Jeelani S., Tuskegee University, US

Numerous studies have been carried out, over a period of several years, on the detection of changes in physical characteristics of polymers subjected to high magnetic fields during the curing stages. Extremely large increases in [...]

Investigation of Thermal and Mechanical Response of Nylon-6 Filaments with the Infusion of Acicular and Spherical Nanoparticles

Mahfuz H., Hasan M.M., Rangari V.K., Jeelani S., Tuskegee University, US

It has been demonstrated in recent years that infusion of nanoparticles in thermoset as well as in thermoplastic polymers can help improve the chemical, thermal, and mechanical properties significantly. The improvement in properties can be [...]

Synthesis & Mechanical Characterization of Carbon/Epoxy Composites Reinforced with SiC Nano Particles

Chisholm N., Mahfuz H., Rangari V., Rodgers R., Jeelani S., Tuskegee Unviersity, US

Room temperature cure Epoxy resin has been doped with SiC nanoparticles through an ultrasonic cavitation process. The modified resin is then utilized in a Vacuum Assisted Resin Transfer Molding (VARTM) process with satin weave carbon [...]
