  1. 11. Modelling and testing of CLT panels for evaluation of stiffness

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Sebastian Svensson Meulmann; Egzon Latifi; [2021]
    Keywords : Cross-laminated timber CLT ; Four-point bending; Bending stiffness; Shear stiffness; Plates; Lamellas;

    Abstract : The use of timber in building structures is steadily increasing. cross laminated timber (CLT) is an engineered wood product made of an uneven number of layers of lamellas glued at an angle of 90 degrees to each other. READ MORE

  3. 12. Polymer Directed Engineering of Novel Cellulose Network

    University essay from KTH/Fiber- och polymerteknologi

    Author : Christel Gradin; Adina Landström; Julia Szecsödy; [2021]
    Keywords : Hydrogel; Carboxylated CNF; TEMPO-oxidation; bis-MPA ammonium dendrimer; Polymer salt bridge; Rheology;

    Abstract : This study investigated a CNF/dendrimer hydrogel and how different concentrations of the carboxylated CNF and bis-MPA ammonium dendrimer affected the hydrogels’ rheological properties. A third generation bis-MPA ammonium dendrimer was diffused into a dispersion of carboxylated cellulose nanofibrils. READ MORE

  4. 13. Industrial Requirements for Cross-Laminated Timber Manufacturing

    University essay from Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Author : Matilda Torneport; [2021]
    Keywords : Cross-laminated timber; CLT industry; Wood species; Adhesive; Strength class; Timber grades;

    Abstract : Wood is a valuable sustainable material that meets the requirements for structural application. Cross-laminated timber (CLT) is a wood-based product that is mainly used in the building industry. Due to the rapid global market increase, a number of new CLT plants are emerging worldwide and thereby a need for standardisation is more than ever. READ MORE

  5. 14. Timber Concrete Composite floors with Cross Laminated Timber - Structural behavior & Design

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Albin Forsberg; Filip Farbäck; [2020]
    Keywords : timber concrete composite; TCC; floors; cross-laminated timber; CLT; structural behavior; design methods; Gamma method; Equivalent gamma method; Extended gamma method; RFEM; first natural frequency; serviceability limit state; ultimate limit state; Technology and Engineering;

    Abstract : På grund av den ökade miljö- och klimatmedvetenheten har övergången till förnybara material påskyndats, och detsamma gäller intresset för träbyggande. Med att bygga högt i trä kommer dock ett flertal konstruktionsmässiga utmaningar, där en av utmaningarna är dynamik på grund av träets låga egenvikt jämfört med andra mer konventionella byggnadsmaterial.

  6. 15. Negative energy elasticity and a model for the behavior of the residual strain in doubly cross-linked gels fabricated by shear strain

    University essay from Uppsala universitet/Polymerkemi

    Author : Therese You; [2020]
    Keywords : Polymer gel; Tetra-PEG; hydrogels; doubly cross-linked gels; shear modulus; energy elasticity;

    Abstract : Doubly cross-linked gels were fabricated based on tetra-poly(ethylene glycol) (Tetra-PEG) by shear strain. These are gels with two network structures present in the same polymeric network. The second network structure is introduced by applying a mechanical field to the first natural network structure.
