2. 1. Thermally Modified Timber : Novel Aspects of Bending Behaviour Towards Grading and Structural Applications

   Author : Joran van Blokland; Stergios Adamopoulos; Anders Olsson; Jan Oscarsson; Mark Hughes; Linnéuniversitetet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; checks; cracks; digital image correlation; four-point static bending; fracture characteristics; grade determining properties; non-destructive testing; Norway spruce; machine learning; outdoor above-ground exposure; timber grading; scanning electron microscopy; scanning of fibre direction; strain distribution; ThermoWood®; weathering; Forestry and Wood Technology; Skog och träteknik; Byggteknik; Civil engineering;

   Abstract : Thermally modified timber (TMT) has gained market share in Europe as an environmentally friendly and durable building material. Unfortunately, TMT products are currently prohibited for use in structural applications as there is insufficient data to estimate the loss in strength due to thermal modification. READ MORE

4. 2. Colour – A Reliable Quality-Control Tool for Industrial Thermowood® Production

   Author : Petteri Torniainen; Dennis Jones; Olov Karlsson; Dick Sandberg; Henrik Veikko Juhani Heräjärvi; Luleå tekniska universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Thermally-modified timber; Thermo-S; Thermo-D; colour Lab; Scots pine; Pinus sylvestris; Norway spruce; Picea abies; quality control; Träteknik; Wood Science and Engineering;

   Abstract : The objective of the work presented in this doctoral thesis has been to correlate the commercial output of  ThermoWood® process with a pre-defined, quantifiable, non-destructive measurable parameter - colour, and to show the feasibility of measurements to be the essential part of the internal and external quality-control system. Colour is the most evident property changed of thermally-modified timber (TMT). READ MORE

5. 3. Drying and thermal modification of wood - studies on influence of sample size, batch size, and climate on wood response

   Author : Björn Källander; Peter Niemz; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Abstract : Research on wood drying and wood modification is primarily done in laboratories, using clear wood specimens treated under well-defined conditions in laboratory cabinets. Laboratory tests differ from industrial treatment both regarding the size and homogeneity of the material treated, and the size of the batch and kiln used. READ MORE

6. 4. Heat treatment of solid wood : effects on absorption, strength and colour

   Author : Dennis Johansson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träfysik; Wood Physics;

   Abstract : Wood is a useful construction material, but it has less desirable properties such as poor durability and poor dimensional stability. These problems can be reduced by using various chemical treatments. Increased environmental awareness has raised the demand for more environmentally friendly methods. READ MORE

7. 5. Studies on Industrial-Scale Thermal Modification of Wood

   Author : Ola Dagbro; Lidia Gurau; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forestry and Wood Technology; Skog och träteknik; Wood Physics;

   Abstract : Wood as a raw material is useful for many purposes even though some properties are less than optimal, for example, dimensional stability and durability. These characteristics can however be improved by different treatment methods. READ MORE
