Interim tests for CELLUWOOD project

Interim tests for CELLUWOOD materials.

CELLUWOOD ( “Laminated Strong Eco-Material for Building Construction Made of Cellulose-Strengthened Wood - Final Outcomes”) is a four years EU project, funded under the Eco Innovation research initiative. The project aims to develop a new range of structural elements made of wood by introducing innovative production elements and includes the use of cellulose instead of petroleum-based glue in the lamination of the timber products. The ‘physical’ results will be the strong eco-beams and columns and their most sustainable manufacturing technologies, in addition to significant environmental and cost benefits of the innovation. These are achieved by the introduction of the (new) technologies from other sectors (e.g. cellulose velvet, biocomposite reinforcement and bio-resin) for innovative uses in the defect removal and repairing, facilitating innovation in the use of nano/micro cellulose and bio-resin technologies in timber reengineering, and the development, testing and demonstration of the novel initiative products.

The CELLUWOOD products include strong glulam Eco-beams and columns manufactured by using bio-based lignin resins and nanocellulose enhanced glue systems. Both innovative building products provide significant environmental benefits.

Coordinator and responsible of the project at AIDIMA: Miguel Ángel Abián

In the case of AIDIMA, this project is co-funded by IVACE (Instituto Valenciano de Competitividad Empresarial) and by the European Regional Development Fund (ERDF).

  2. 2. 2 WP 8: ASSESSMENT OF CELLUWOOD MATERIAL
  3. 3. 3 Previously, in WP7 some lignin, PUR and MUF beams where manufactured at TECNIFUSTA for interim testing. Those interim tests led to changes in the formulation of the lignin resin by CHIMAR in order to achieve a satisfactory and effective final resin. In 2014, 20 complete beams (nominal dimensions: 120 x 120 x 2200 mm) were manufactured at TECNIFUSTA in collaboration with CHIMAR and AIDIMA: • 10 beams with their lamellae glued by the final lignin resin developed in the project (CELLUWOOD beams). • 10 beams with their lamellae glued by commercial PUR. All lamellae were made of timber classified as C24. 10 commercial beams (nominal dimensions: 120 x 120 x 2200 mm) made with MUF resin were used in order to compare strength and behaviour with the other 20 beams. The commercial beams are classified as GL24h. All beams were made of Picea abies wood.
