2. 16. A toolbox for improving the processability of composites with a high content of thermomechanical pulp

   Author : Seyedehsan Hosseini; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interface.; thermomechanical pulp; magnesium stearate; mechanical properties; composite; molybdenum disulfide; AKD;

   Abstract : The use of oil-based products causes large volumes of non-biodegradable waste and contributes to climate changes. Focus has consequently shifted towards the use of polymers derived from wood. The processability of such polymers, however, presents a challenge but this can be overcome through the use of composite materials, i.e. READ MORE

4. 17. Experimental methods to determine model parameters for failure modes of CFRP

   Author : Daniel Svensson; Ulf Stigh; Svante Alfredsson; Högskolan i Skövde; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composite; delamination; compressive failure; energy release rate; cohesive modelling; Teknik; Technology;

   Abstract : The focus of this thesis is to develop methods to predict the damage response of Carbon Fibre Reinforced Polymers (CFRP). In the pursuit of reducing the manufacturing cost and weight of CFRP components, it is crucial to enable modelling of the non-linear response associated with various failure modes. READ MORE

5. 18. Physical properties of dispersions and composites containing surface-grafted cellulose nanocrystals

   Author : Lilian Forsgren; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Composite; Cellulose; Thermal stability; Cellulose nanocrystals; Tensile properties; Rheology;

   Abstract : The needs and requests from the society for non-fossil-based materials as well as more lightweight products are constantly increasing. The increasing awareness of the sustainability of the resources available paralleled by a growing population, point to a need for changes, if the population also aim for constantly higher standard of living.

6. 19. Shapeable cellulosic materials

   Author : Malin Brodin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composite; polyethylene; coagulation; material properties; cellulose ester; interactions; gel; cellulose; ionic liquid;

   Abstract : ABSTRACTA palette of materials has been developed by the oil and gas sector. The expected depletion of fossil resources and the stress on the climate from burning them has, however, turned the world’s attention to renewable resources. READ MORE

7. 20. Structural and Physical Effects of Carbon Nanofillers in Thermoplastic and Thermosetting Polymer Systems

   Author : Sanjukta Chatterjee; Svensson Svante; Ritva Serimaa; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer; Composite; Carbon nanotube; Graphene;

   Abstract : Ever since the discovery of carbon nano materials like carbon nanotube (CNT) and graphene, this class of materials has gained significant attention due to their exotic properties. The principle idea of my present research project is to understand the novel improvements induced in polymer matrices with inclusion of the nanofillers. READ MORE
