Competitive production of wood fibre based composites

Reference number
Coordinator RISE SICOMP AB - Swerea SICOMP AB, Mölndal
Funding from Vinnova SEK 3 369 000
Project duration November 2016 - December 2018
Status Completed
Venture Challenge-driven innovation - Phase 2 Collaboration

Purpose and goal

The purpose was to verify new innovative technology for chemical modification of thermomechanical pulp (TMP) in the mechanical pulp manufacturing process. The aim was to develop a competitive manufacturing method for the production of fibres that are compatible with different plastics, so that composites can be manufactured without any other additives, with at least as good properties as existing commercial plastics and wood fibre composites. A result bank has been generated and many milestones have been achieved.

Expected effects and result

A patent describing the innovation was granted (SE 1651139 A1, SE 540 288 C2). Large number of combinations of refining settings and chemicals were tested in a series of pilot trials. The properties of composites with a selection of modified fibres were compared to pure plastics and composites with conventional TMP fibres with and without compatibilizer. Demonstrators in the form of cups, handles and chair chassis have been produced from the developed materials.

Planned approach and implementation

Pilot trials were carried out for production of chemically modified TMP fibres. Different kinds of chemicals were tested. The surface properties of the fibres were characterized: contact angle and spectroscopy (ATR and NMR). Composites were manufactured: processability, moisture absorption and mechanical properties were evaluated. Demonstrators for various uses were made: challenges were identified, solutions were proposed and tested.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
