2. 11. Joining of Carbon Fibre Reinforced Plastics for Automotive Applications

   Author : Gordon Kelly; KTH; []
   Keywords : Composite; laminate; bearing strength; joining; load introduction; hybrid joint; finite element analysis; mechanical testing;

   Abstract : The introduction of carbon-fibre reinforced plastics in loadbearing automotive structures provides a great potential toreduce vehicle weight and fuel consumption. To enable themanufacture and assembly of composite structural parts,reliable and cost-effective joining technologies must bedeveloped. READ MORE

4. 12. Ageing behavior of plastics used in automotive fuel systems

   Author : Xin-Feng Wei; Mikael S. Hedenqvist; Richard Olsson; Ulf W Gedde; Pieter Gijsman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automotive; Ageing; Polyamide; Diesel; Biodiesel; Diffusion; Oxidation; Plasticizer migration; Mechanical properties; Fracture behavior.; Fordon; Åldrande; Polyamid; Diesel; Biodiesel; Diffusion; Oxidation; Mjukgöraravgång; Mekaniska egenskaper; Brottegenskaper;

   Abstract : The increase in service temperature and the use of biobased fuels, such as biodiesel, have raised concerns on the short/long-term performance of plastic components used in automotive fuel systems.In this work the ageing behavior of unreinforced and glass-fibre reinforced polyamide 12 (PA12), exposed to three different fuels (petroleum diesel, biodiesel, and a mixture of these (80/20)) at high temperature, was investigated.

5. 13. Mechanical and thermal properties of recycled WEEE plastic blends

   Author : Sandra Tostar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SEBS; HIPS; extrusion; WEEE; WEEEBR; melt-blending; plastics recycling; gamma irradiation; PP; ABS; compatibilization; polymer degradation;

   Abstract : Electronic waste is the fastest growing waste stream today, and the recycling of the plastics from waste electrical and electronic equipment (WEEE) has attracted great attention recently for environmental reasons and to comply with the European Union’s (EUs) WEEE Directive. The plastics fraction in WEEE is between 20 and 35 weight % (wt%). READ MORE

6. 14. Exploring different thermoplastics from lignocellulosic building blocks and monomers

   Author : Olivier Bonjour; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biobased plastics; Biobased polymers; Polymethacrylates; Polycarbonates; Polyesters; Poly beta-thioether ester s; Chemical recycling; Biobased plastics; Biobased polymers; Polycarbonates; Polymethacrylates; Poly beta-thioether ester s; Polyesters; Chemical recycling;

   Abstract : The need to replace conventional fossil-based plastics is becoming more imperative. As climate change is more visibly affecting our society, employing non-sustainable resources to produce plastics is aggravating the problem. READ MORE

7. 15. Functional Properties and Morphology of Recycled Post-consumer WEEE Thermoplastic Blends
