  1. 6. Highly-filled biocomposites: modelling, processing, and characterization

    Författare :Sajjad Pashazadehgaznagh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; fiber orientation; rheology.; Wood plastic composites WPCs ; extrusion; surface instability;

    Sammanfattning : The use of polymer with natural fiber reinforcements is expected to increase significantly. This can be noted in several industrial sectors of strategic importance for Sweden, such as automotive, packaging, construction, and furniture industries. LÄS MER

  3. 7. Characterisation of thermally modified wood for use as component in biobased building materials

    Författare :Susanna Källbom; Magnus Wålinder; Dennis Jones; Kristiina Lillqvist; Kristoffer Segerholm; Marko Petrič; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermally modified wood TMW components; surface properties; inverse gas chromatography IGC ; water sorption; dynamic vapour sorption DVS ; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : The building sector shows growing interest in biobased building materials. Wood components, here defined as ground or milled wood, i.e. by-products (residuals/residues) from wood processing, such as sawdust or shavings, are valuable raw materials for new types of durable biocomposites suitable for outdoor building applications.

  4. 8. Deformation and Fracture Behavior of Transparent Wood-Polymer Biocomposites

    Författare :Erik Jungstedt; Lars Berglund; Sören Östlund; Bent Sørensen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; fracture mechanics; strain field measurement; cohesive zone modeling; mechanical properties; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : Transparent wood-polymer biocomposites (TWPBs) are interesting wood-based materials with a unique combination of optical transmittance and mechanical properties. The wood substrate is delignified (removal of lignin) while the wood microstructure is preserved. LÄS MER

  5. 9. Additive-Driven Improvements in Interfacial Properties and Processing of TMP-Polymer Composites

    Författare :Seyedehsan Hosseini; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; molybdenum disulfide; magnesium stearate; thermomechanical pulp; alkyl ketene dimer; friction; rheology;

    Sammanfattning : Efforts to address environmental concerns have resulted in new regulations designed to plan the reduction of plastic and synthetic polymer usage, necessitating the search for sustainable natural alternatives with comparable cost-effectiveness and mechanical performance. Thermomechanical pulp (TMP) fibres are one of the most affordable natural fibres that have no chemical refining in production, production have a high yield of 90-98% and TMP fibres have been demonstrated to improve the mechanical characteristics (strength, stiffness and toughness) of wood-polymer composites (WPCs) compared to the pure polymer.

  7. 10. Thermoset resins using technical lignin as a base constituent

    Författare :Marcus Jawerth; Mats Johansson; Heikki Tenhu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The need to find sustainable paths for our society is imminent to tackle environmental concerns of today. The majority of all plastic materials are produced from crude oil but in the future a much larger portion must originate from renewable resources to address some of these problems. LÄS MER
