Ausgangslage

Foam core development - Development of bio-based foam precursors - Adaptation of the properties to the product Particle surface layer - Widenth process parameter window (Temperature) - Synchronisation of core and surface layer Sandwich panel properties - Characterise and predict mechanical properties of the panel

Ziel

Development of a new generation of ultra-light particleboard with the following characteristics: Average density below 350 kg/m3; Economically competitive; Bio-based and biodegradable

Kernkompetenzen

wood-based panels, sandwich panel, low temperature curing adhesive, polymer foaming, composite mechanics

Ergebnis

Ultra light particle board with a PLA/PMMA blend foam core and particle board surface layer.

Ausblick

The second phase of the project will investigate the use of wood fibres and cellulose nanofibrils to improve the foam stability
