Abstract: The present disclosure relates to composite materials comprising a resin and at least one sheet that comprise optionally cellulose filaments (CF), fillers and optionally reinforcing fibers as well as methods for the preparation thereof. The methods comprise impregnating the sheets comprising the cellulose filaments, fillers and optionally the reinforcing fibers or a stack thereof with resin. The composite materials can optionally comprise at least one other sheet, the at least one other sheet being different from the at least one sheet and comprising fibers chosen from wood pulp, fiberglass, natural fibers and mixtures thereof. The sheet can also be in the form of a panel of a preform.

Abstract: There are provided gypsum panels, sheets and multi-layer sheets as well as methods of preparation thereof. For example, there are provided cellulose filament-reinforced gypsum panels, sheets and multi-layer sheets and methods of preparation thereof. For example, in such gypsum panels, sheets and multi-layer sheets gypsum is bound with cellulose filaments to strengthen the gypsum panels, sheets and multi-layer sheets. The cellulose filament-reinforced gypsum panel can be, for example, a core comprising a honeycomb or corrugated structure. There are also provided aqueous suspensions comprising cellulose filaments and CaSO4.2H2O.
