Cold tack of the adhesive is absolutely necessary in plywood production. Insufficient cold tack is usually seen as a typical adhesive problem and leads to complaints. An analytical method has been developed that proves, that many other factors also play a role. For example, cold tack decreases when the wood moisture content increases or increases with temperature. Based on the analytical data, a statistical model was build that predicts how cold tack reacts on the combination of many influencing factors. This model is used to educated plywood pro-ducers, leading to a reduction of failure in plywood production.

Environmental assessment of bio-fibre reinforced composites during the innovation process – Life cycle analysis and Upscaling
Despite replacing fossil raw material, the environmental performance of bio-based fibre rein-forced composites is not per se more valuable-. Resulting from the change in material compo-sition, the manufacturing process needs to be adjusted, such as the injection molding forming process. Detailed analyses and comparisons with reference materials are necessary for the assessment of environmental performance, due to changed requirements for production pro-cesses, for material characteristics, as well as for end product and service life.
On April 21, 2016, the interim results of the qualification network "Fehra - Pinewood use" were presented in the “business centre of Lower Austria” in St. Pölten. The nine speakers had the task to summarise the input from 30 partners and the work of 22 workshops in just one afternoon.
In the furniture and flooring industry melamine decorative surfaces are used. In the first production step decorative papers are impregnated with melamine resins and industrially pre-dried in an impregnating channel. Tailored resins and their penetration behaviour thereby fix the final product properties. It is essential to know these properties – so on the basis of an objective method of determination we are able to predict this behaviour. This allows the use of new resins and the processing of difficult and sometimes old decorative papers. Thus an economic competitive advantage for the industrial partner is given.
Cellulose fibers find their applications in sensitive areas such as cosmetics, hygiene und medicine. Therefore the property softness is found among the fundamental quality parameters. So far, softness was determined by means of laborious panel test. Now, a more efficient method was successfully developed by the project team consisting of researchers from Lenzing AG and Kompetenzzentrum Holz GmbH.
In order to be free from dependency on fossil fuels such as coal, gas or crude oil, the energy industries have high hopes on wind power because it is sustainable and available in plenty. However, there is one hitch: Although the wind power plant generates renewable, green energy the plant is made from eco-unfriendly materials. The rotor blades of wind turbines are generally made from glass fiber reinforced plastics. After 20 to 25 years of service, the plant reaches its end of life cycle and in this context the disposal of the fiber- reinforced plastics is problematic.

Accompanying environmental and techno-economic assessments of lignin-based resins during the innovation process
The accompanying assessments of bio-based products during the innovation process by considering environmental and techno-economic aspects supports the implementation of these products on the market. Barriers regarding the use of lignin-based resins are mostly linked to technical and economic issues, whereas the incentives are based on the expected lower environmental impacts of the lignin-based resins compared to the conventional resins. The environmental assessment conducted within the study emphasis this incentive.

Together with Borealis Polyolefine and Budapest University of Technology, notched impact strength of polypropylene (PP) based Natural Fiber Composites (NFC) has been highly in-creased by the development of innovative hybrid materials. We used special polymeric fibers as impact modifiers for NFC. In the present development, PP impregnated long fibers were applied for the first time as impact modifier for NFC. Longer fibers are more effective rein-forcements in thermoplastics than shorter fibers. Materials with high impact strength, which show improved crash performance, are of importance in the automotive industry.
Closing the loops for process waters in the pulp and paper industry is an important step to minimize the environmental footprint. It enables significant reduction of water consumption, but on the other hand undesired wood components are enriched within the process. In collaboration with Lenzing AG, a highly versatile extraction method was developed to enable characterisation of the diverse components in aqueous samples. The novel method combines the purification, enrichment or fractionation steps and makes therefore process control easier and faster.

Non-destructive testing (NDT) of components by means of microcomputed tomography (XCT) is an important task in many fields, e.g. in the automotive and aerospace sector. However, the demands towards NDT methods are continuously increasing due to the development of advanced, complex material systems. Accordingly, new multi-disciplinary NDT approaches have to be developed to approach the challenges in the in-depth 3D characterization of advanced materials.

Exactly ten years ago the Wood Carinthian Competence Center (W3C) was founded in St. Veit/Glan, as one of four locations of the “Kompetenzzentrum Holz GmbH” in Austria. Since then, an impressive chapter of successful research, development and innovation in Carinthia has been written. Because of close cooperation with numerous business partners from the wood material industry, a value of several hundred million euros were generated and based on the research results a significant number of high-quality jobs have been created in the past decade in Carinthia.
On Friday, 22nd April 2016 Wood K plus took the opportunity to present the comprehensive research-competence of the centre to the visitors of the Long Night of Research at the locations Linz, Klagenfurt and Tulln.
Adhesive distribution plays a major role for the properties of industrial wood composites, such as particle boards, MDF and OSB. The most common adhesive to produce these boards, urea - formaldehyde resin, is colourless when cured thus making the investigation of adhesive distribution merely impossible. In this project, methods to colour both wood and adhesive after the board is produced, enable the investigation of adhesive distribution. The knowledge thus obtained allowed the development of better adhesive, better boards and the reduction of chemicals needed.
