Effect of Nanoclay Content on Mechanical Behaviour of TGDDM Epoxy Nanocomposites

Huong N.T.P., Crosky A., Qi B., Kelly D., Li D.C., The University of New South Wales, AU

Exfoliated nanocomposites based on tetraglycidyldiamino diphenylmethane (TGDDM) cured by diethyltoluene diamine (DETDA) reinforced with 1-20 phr of a commercial nanoclay (I30E) were prepared. The effect of the nanoclay content on the compressive modulus of the [...]

Recent Applications of Mesoscale Modeling to Nanotechnology and Drug Delivery

Maiti A., Wescott J., Kung P., Goldbeck-Wood G., Accelrys Inc., US

Technologically important nanomaterials come in all shapes and sizes. They can range from small molecules to complex composites and mixtures. Depending upon the spatial dimensions of the system and properties under investigation, computer modeling of [...]

A Modeling Tool for Contact Probe Tests on Nano-Particle Filled Materials

Tseng K.K., Vanderbilt University, US

With the recent advances in nano-scale science and engineering, materials containing reinforcement with superior mechanical properties can be found in many advanced products. The accurate prediction of the mechanical properties of this class of composite [...]

Sustainable Nanocomposite Materials from Cellulosic Plastics

Misra M., Park H.M., Mohanty A.K., Drzal L.T., Michigan State University, US

Sustainable 'green' nanocomposites were successfully fabricated from cellulose acetate (CA), triethyl citrate (TEC) plasticizer and organically modified clay. Maleic anhydride grafted cellulose acetate butyrate (MA-g-CAB) was used as a compatibilizer. The effect of compatibilizer proportions [...]

Carbon Nanofiber Reinforced Carbon/Polymer Composites

Joshi M., Bhattacharyya A., Indian Institute of Technology, IN

Conventional carbon fiber reinforced phenolic resins are widely used to prepare carbon/carbon composites due to their high carbon yield. Property enhancement of carbon fabric/phenolic composites is possible through carbon nanomaterial dispersion in the matrix. The [...]

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 [...]

Carbon Nanotube- and Nanofibre-reinforced Polymer Fibres

Shaffer M.S.P., Sandler J.K.W., Pegel S., Windle A.H., Gojny F., Schulte K., Cadek M., Blau W.J., Lohmar J., van Es M., Imperial College, UK

A range of multi-wall carbon nanotubes and carbon nanofibres were mixed with a polyamide-12 matrix using a twin-screw microextruder, and the resulting blends used to produce a series of reinforced polymer fibres. The aim was [...]
