In this paper, the influence of vacuum infiltration lightweight ceramic aggregates as fillers in polymeric concretes was described. first stage investigation, a set with high open porosity about 27% produced on basis industrial wastes. Ceramic size 2 to 4 mm, hereinafter referred granules, were using contaminated glass cullet waste and coal shale. The effectiveness granule epoxy resin productio...

Submitted for the MAR05 Meeting of The American Physical Society A Coarse-Grained Simulation of Rheology of Colloidal Suspensions and Polymer Nano-Composites VICTOR PRYAMITSYN, University of Texas@Austin, VENKAT GANESAN — We extend DPD model to address dynamical properties of suspensions of solid particles in complex fluids. In this approach, the solvent particles (polymer segments) are represe...

Environmentally benign processes involving supercritical fluids have been investigated as alternatives to conventional solvents due to the increasing awareness of environmental issues. Carbon dioxide is considered to be a “green” solvent as it is nontoxic, nonflammable and non-reactive under most conditions. Supercritical carbon dioxide (scCO2) is a widely used solvent to enhance processing per...

Biodegradable poly(DL-lactic acid) (PLA) and poly(lactic-co-glycolic acid) (PLGA) microparticles with tunable size, shape, internal structure and surface morphology were produced by counter-current flow focusing in axisymmetric (3D) glass capillary devices. The dispersed phase was composed of 0.5-2 wt % polymer solution in a volatile organic solvent (ethyl acetate or dichloromethane) and the co...

One of the fundamental open questions in condensed matter science is the origin of the unique universal characteristics of glasses. Among them, the Boson peak (BP) and the first sharp diffraction peak (FSDP) are directly related with the disordered nature of these solids. The lack of widely accepted understanding of the origin of these features makes the characterization of glass forming system...

Polymeric particulate composites are widely used in engineering systems where they subjected to impact loading – at a variety of temperatures leading high strain rate deformation. These materials highly and temperature dependent, this dependence must be well understood for effective design. It is not uncommon many these display mechanical responses that range from glassy brittle rubbery hyperel...

Predicting the glass-transition temperatures (Tg) of glass-forming polymers is critical importance as it governs thermophysical properties polymeric materials. The cheminformatics approaches based on machine learning algorithms are becoming very useful in predicting quantitative relationships between key molecular descriptors and various physical In this work, we developed a modeling framework ...

This study investigated the effect of aviation turbine fuel exposure on interlaminar and in-plane shear properties E-glass/epoxy composite. The two types test specimens, namely bare resin-coated specimens with varying thicknesses as per ASTM standard, were made out composite to evaluate their properties. These all immersed inside for months then afterward reduction mechanical like tests experim...

The viability of a novel sustainable polymeric composite material, based on photocurable linseed oil resin was explored, with a view to exploiting its potential in marine environments. The study focused on a UV-curable resin subjected to setting through photoinitiated cationic polymerisation. Deployment of heterogeneous solid catalysts, containing isolated Brønsted acid centres, further improve...

This paper presents a study of hole quality and energy consumption in the process of drilling a thermoplastic polymeric material, polyether-ether-ketone, reinforced with 30% glass fibers (PEEK-GF30). PEEK-GF30's capacity to be machined has focused on turning operations. Studies of drilling involving thermoplastic polymeric materials have considered materials with other types of matrices, or rei...
