  1. 1. Characterisation of green-glued wood adhesive bonds

    Författare :Magdalena Sterley; Erik Serrano; Hans Petersson; Klaus Richter; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; green gluing; finger jointing; durability; shear strength; wood failure percentage; fracture energy; tensile strength; PUR adhesive; Byggteknik; Civil engineering;

    Sammanfattning : The gluing of unseasoned wood, called green gluing, is a relatively new sawmill process, implying a radically changed order of material flow in the production of value-added wood-based products. It facilitates the enhancement of raw material recovery and value yield by integrating defect elimination and gluing already before kiln drying. LÄS MER

  3. 2. Exploring the Wood Adhesive Performance of Wheat Gluten

    Författare :Petra Nordqvist; Eva Malmström Jonsson; Mats Johansson; Bo Mattiasson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plant protein; wood adhesive; mechanical properties; wheat gluten; soy protein isolate; gliadin; glutenin; adhesion; hydrolysis; heat treatment; AFM;

    Sammanfattning : The increasing environmental concern has reawakened an interest in materials based on renewable resources as replacement for petroleum-based materials. The main objective of this thesis was to explore plant proteins, more specifically wheat gluten, as a binder in wood adhesives intended for typical solid wood applications such as furniture and flooring.

  4. 3. Micromechanical retention and chemical bonding to polycrystalline dental ceramics : studies on aluminum oxide and stabilized zirconium dioxide

    Författare :Evaggelia Papia; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alumina; aluminium oxide; bond strength; oxide ceramics; polycrystalline dental ceramics; stabilized zirconium dioxide; Y-TZP; zirconia; adhesive cements;

    Sammanfattning : Det pågår en ständig utveckling av olika dentala material avsedda föratt ersätta förlorad tandsubstans. En materialgrupp som är särskiltintressant är höghållfasta keramiska material, oxidkeramer så somyttriumdioxidstabiliserad tetragonal polykristallin zirkoniumdioxid(Y-TZP). LÄS MER

  5. 4. Steel members strengthened with carbon fibre reinforced polymers - A study of local and global structural behaviour

    Författare :Dag Linghoff; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcement; CFRP laminate; adhesive; design;

    Sammanfattning : Investigations have been conducted by several research groups to study the effect of using carbon fibre reinforced polymers (CFRP) as reinforcement on steel beams and a brief summary of this work is given in this thesis. Laboratory studies of reinforced steel beams demonstrate that the bending stiffness and the ultimate load-carrying capacity can be significantly increased. LÄS MER

  7. 5. Novel RF MEMS Switch and Packaging Concepts

    Författare :Joachim Oberhammer; KTH; []
    Nyckelord :0-level packaging; adhesive bonding; BCB; benzocyclobutene; bond strength; contact printing; film actuator; glass lid encapsulation; glass lid packaging; helium leak test; hermetic packaging; hermeticity; high isolation switch; low stress silicon nitride; low volt; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Radio-frequency microelectromechanical systems (RF~MEMS) are highly miniaturized devices intended to switch, modulate, filter or tune electrical signals from DC to microwave frequencies. The micromachining techniques used to fabricate these components are based on the standard clean-room manufacturing processes for high-volume integrated semiconductor circuits. LÄS MER
