1. 1. CHARACTERISATION OF CROSS LAMINATED TIMBER PROPERTIES

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Emil Nilsson; [2021]
   Keywords : CLT; cross laminated timber; in-plane loading; out-of-plane loading; beam; rolling shear modulus; experimental tests; FE-modelling; Technology and Engineering;

   Abstract : This project concerns an analysis of a hitherto untested method for determining the modulus of elasticity (MoE) and shear modulus parallel to grain, as well as the rolling shear modulus of cross laminated timber (CLT) through 3-point bending tests. A review of analytical models and methods is included, followed by an evaluation of the effect of the annual ring orientation and shear stress distribution at shear loading of individual board cross-sections.

3. 2. Enhancement of Phenol Formaldehyde Adhesive with Crystalline Nano Cellulose

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

   Author : Johan Ekstrand; [2019]
   Keywords : Nano Cellulose; Fibrillated cellulose; Wood Adhesive; Shear strength; Adhesive Enhancement; Formaldehyde adhesive; Phenol Formaldehyde;

   Abstract : Abstract The wood industries to this day use almost exclusively petroleum derived adhesives that are based mainly on the reaction of formaldehyde with urea, melamine or phenol. These adhesives have low cost and good adjustable properties which makes it hard for bio-based alternatives to compete. READ MORE

4. 3. Finger-jointing of acetylated Scots pine using a conventional MUF resin

   University essay from KTH/Byggnadsmaterial

   Author : Christian Wincrantz; [2018]
   Keywords : Acetylated wood; Scots pine; juvenile wood; finger-jointing; mechanical properties modulus of rupture.;

   Abstract : Acetylation of wood is a modification technique that chemically alters the wood substance and enhances several properties of wood. The basic principle is to impregnate wood with acetic anhydride to react and replace OH-groups with acetyl groups in the wood cell wall. READ MORE

5. 4. Evaluation of non-destructive test methods for predicting the static bending stiffness and strength properties of thermally modified timber

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

   Author : Pu Shuchan; [2017]
   Keywords : Non destructive technologies;

   Abstract : Non-destructive technologies have been applied on predicting the stiffness and strength properties of timber for decades. However, these technologies have rarely been investigated on predicting the properties of thermally modified timber. READ MORE

6. 5. Bending properties of commercial wood-based panels by NDT methods

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

   Author : Francesco Poggi; [2017]
   Keywords : Wood-based panels; Non-destructive testing; Bending properties; Resonance vibration; Time-of-flight; Modulus of elasticity; Modulus of rupture; Stress wave velocity; Relative humidity.;

   Abstract : This thesis work focuses mainly on the application of non-destructive testing (NDT) methods on wood-based panels (WBP) in order to estimate the bending properties. To prove the accuracy and applicability of these methods on WBP, their results are correlated with results from a standardized static bending test. READ MORE
