1. Melt flow and surface stability effects on polymer flammability : A study on polystyrene, flexible polyurethane foam and polyolefin composites
Abstract : Our ability to accurately determine the flammability properties of polymers is hampered bythe erratic effects of deformation and liquid flow that occur during polymer combustion.This study aims to improve the understanding of such effects at several levels: The often obvious impact of melt flow on standardized flammability test methods forelectrical appliances is described to identify the need and to motivate others to worktowards an improved material characterization.

3. Melt Spun Electro-Conductive Polymer Composite Fibers
Abstract : One interesting approach is the development of conductive polymer composite fibers for innovative textile applications such as in sensors, actuators and electrostatic discharge. In this study, conductive polymer composite fibers were prepared using several different blends containing conductive components: a conjugated polymer (polyaniline-complex) and/or carbon nanotubes.

4. Conduction laser welding : modelling of melt pool with free surface deformation
Abstract : Laser welding is commonly used in the automotive-, steel- and aerospace industry. It is a highly non-linear and coupled process where the weld geometry is strongly affected by the flow pattern in the melt pool. Experimental observations are challenging since the melt pool and melt flow below the surface are not yet accessible during welding. READ MORE

5. Electronic Waste Plastics Characterisation and Recycling by Melt-processing
Abstract : Melt-processing of blended plastics from waste electrical and electronic equipment (WEEE) is a method to facilitate mechanical recycling, and this might improve the recycling conditions and increase the amounts of plastics being recycled. To ensure the quality of melt-blended plastic waste, it is essential to know the composition of the incoming material and then possibly improve the compatibility between the different polymer phases.
