Zusammenfassung:	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. La presente descripción se refiere a materiales compuestos que comprenden una resina y al menos una lámina que comprende opcionalmente filamentos de celulosa (CF), rellenos y opcionalmente fibras de refuerzo así como métodos para la preparación de los mismos; los métodos comprenden impregnar la lámina que comprende los filamentos de celulosa, rellenos y opcionalmente las fibras de refuerzo o una pila de los mismos con resina; los materiales compuestos pueden comprender opcionalmente al menos otra lámina, la al menos otra lámina es diferente de la al menos una lámina y que comprende fibras elegidas de pulpa de madera, fibra de vidrio, fibras naturales y mezclas de los mismos; la lámina también puede estar en la forma de un panel de unapreforma.
