| Wood modification & re-engineering
Date: March 2008 Summary: This report details the final outcomes from the Forestry Commission and Cairngorm National Park Authority funded project ‘Maximising the potential of UK grown Scots pine falling boards’ (contract number FG10/05). Date: December 2007 Summary: New bio resin adhesives which could replace all or part of the phenolic component in existing glued wood products is an attractive opportunity for the forest products industry. The need is to deliver this environmentally improved system without sacrificing high durability or ease of bonding. The work within this project will continue to appraise the status of bio resins worldwide and the drivers and barriers dictating commercial growth, their fitness for purpose and viability for use in re-engineered wood products. Date: June 2005 Summary: The principle objective of the project was to better utilise low value small diameter oak stems. In order to achieve the objective, the concept was devised whereby small diameter oak stems would be cut into four quarters, the edges machined and the sections bonded back together in a reverse orientation using a moisture insensitive adhesive. This would result in a square beam with a void running up the centre. The project has proven that the concept works very well. The process of constructing inside out beams in the ëgreení state has been streamlined, and in theory, could easily be semi-automated. Date: February 2005 Summary: The Indurite process of adding density to timber by impregnation with a starch solution that is cross linked by heat to solidify the material has real possibilities for the UK timber industry. With large volumes of low density material being produced and the likelihood of this increasing in the future, a process that could add value to the resource was worthy of investigation. The results observed with Radiata pine had not only proved impressive put profitable making highly durable and colour fast flooring out of a low density, fast grown material. This information paper sets out the findings of the evaluation work carried out at BRE on the use of the Indurite solution with UK species and the resultant effects on a range of mechanical and physical properties, and addresses potential end use applications for treated material. Date: February 2004 Summary: This report presents the progress and results from the first of four work tasks in a series of eight, to utilise low value small oak stems and other hardwood species by using a novel cutting and jointing technique to produce re-engineered components. Date: February 2004 Summary: This report presents the results to date from the project ëObtaining better utilisation of UK grown small diameter Oak stems and other hardwood species using a novel sawing pattern for the production of structural membersí. The project was funded by the Forestry Commission under contract number PPD 24/02, and is due to finish in September 2004. Date: February 2003 Summary: This report details the results of a study into the potential of Wood Plastic Composites (WPCs*) and the impact of these and other composite materials, such as Fibre Reinforced Polymerics (FRPs), on the UK forest products industry. This output represents the Review Report due March 2003 of project PPD27/02 full title "UK Timber/Waste Plastic Composites" The project objective is to investigate the potential of composites made from low grade or reject UK timber and post consumer plastic waste such as HDPE (high density polyethylene), together with structural reinforcement. Date: August 2001 Summary: The aim of this project is to develop new methods for exploiting a range of environmentally and socially acceptable techniques for enhancing the resistance of timber to deterioration due to moisture, while improving their performance and fitness for purpose, and their application to the UK timber resource. In many European countries there has been considerable investment in the development of wood modification. Several of these processes have now been commercialised and the sale of imported modified timber has now begun. This represents both a threat to the use of home grown timber and a missed opportunity. |  |
