  1. 16. Carbon fibre reinforced polymers for strengthening of structural elements

    Author : Anders Carolin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : There is a large need for strengthening of concrete structures all around the world. There can be many reasons for strengthening, increased loads, design and construction faults, change of structural system, and so on. The need exists for both strengthening in flexure as well as in shear. READ MORE

  2. 17. ATMP Process : Improved Energy Efficiency in TMP Refining Utilizing Selective Wood Disintegration and Targeted Application of Chemicals

    Author : Dmitri Gorski; Per Engstrand; Jan Hill; Lars Johansson; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ATMP; TMP; Hydrogen Peroxide; Magnesium Hydroxide; Mechanical Pre-Treatment; Fibre Characterisation; Refiner Bleaching; SC Paper; Newsprint; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : This thesis is focused on the novel wood chip refining process called AdvancedThermomechanical Pulp (ATMP) refining. ATMP consists of mechanical pretreatmentof chips in Impressafiner and Fiberizer prior to first stage refining atincreased intensity. READ MORE

  3. 18. Glass mat reinforced thermoplastics - material, process and selected applications

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material technology; recycling; sound absorption; energy absorption; vibrational energy; microtension; processing; Glass fibre; thermoplastics; Materiallära; materialteknik;

    Abstract : The work presented in this thesis covers the processing of glass mat reinforced thermoplastics, GMT, and the mechanical properties of this material group. The thesis evaluates the possibilities of the material group from a processing and mechanical properties point of view. READ MORE

  4. 19. Interactions between Wood Polymers in Wood Cell Walls and Cellulose/Hemicellulose Biocomposites

    Author : Jasna Stevanic Srndovic; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic FTIR spectroscopy; viscoelasticity; orientation; Norway spruce; protein; glucomannan; xyloglucan; polymer interactions; pectin; imaging FTIR microscopy; primary cell wall; nanocomposite films; dynamic 2D FTIR spectroscopy; xylan; wood fibre; cellulose; secondary cell wall; DMA; lignin;

    Abstract : A wood fibre is a complex multi component biocomposite that is hierarchically organised. The arrangement of a wood fibre on the ultrastructural level is highlycontrolled by the interactions between the main structural polymers, i.e. cellulose, various hemicelluloses and lignin, as well as in some parts also pectin and protein.

  5. 20. Strength Properties of Paper produced from Softwood Kraft Pulp : Pulp Mixture, Reinforcement and Sheet Stratification

    Author : Hanna Karlsson; Luciano Beghello; Lars Nilsson; Lennart Stolpe; Öyvind Gregersen; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper strength; tensile strength; tearing resistance; folding endurance; fracture toughness; handsheet former; stratify; multilayer; multiply; reinforcement; refining; beating; abaca; glass fibre; polyester; lyocell; softwood; bond strength; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

    Abstract : For paper producers, an understanding of the development of strength properties in the paper is of uttermost importance. Strong papers are important operators both in the traditional paper industry as well as in new fields of application, such as fibre-based packaging, furniture and light-weight building material.
