Behaviour of Polymer Filled Composites for Novel Polymer Railway Sleepers

Effective thermal conductivity of metal filled polymer composites

Theoretical model for predicting effective thermal conductivity (ETC) of metal filled polymer composites has been developed. The concept of averaging the temperature field within different phases has been used. Resistor model has been applied to determine ETC of polymer composites. A parameter estimation technique has been applied to determine the inclination angle θ. An effort has been made to...

Thermal Conductivity of Polymer Composites Filled with Nanofillers

Polymer nanocomposites are composed of polymer materials reinforced with nano fillers.In the present study the effective thermal conductivity of the composites filled with nanofillers has been investigated using commercially available finite element software ABAQUS 6.11. The nanofillers used were alumina particles and multi-walled carbon nanotubes (MWNTs) and the matrix was considered to be mad...

Polymer Composites for Bone Reconstruction

The need for reconstructive surgery of bones is continuously increasing along with the ageing of the population as well as the increase of traumatologic injuries. In the United States, the number of bone grafts was 350,000 in 2001. Nowadays, over 500,000 bone graft procedures are performed annually, and approximately 2.2 million worldwide (Giannoudis et al., 2005). The estimated cost of these p...

Polymer Microvascular Network Composites

Microvascular networks show promise for applications such as selfhealing, self-cooling, and structural damage sensing. Fluid-filled micro-scale channels have been investigated extensively in the field of microfluidics, but threedimensional networks in polymeric structural materials have been achieved only recently. The purpose of microvascular network integration is to provide a vehicle for the...
