Abstract: A composite and method for producing the composite by incorporating wood or wood pulp fibres with a suitable thermoplastic polymer and coupling agent are described. Homogeneous, void-free transparent/translucent thermoplastic materials in the form of pellets, films or three-dimensional moldable products are produced. The wood pulp fibres can be discrete natural fibres, and flexible assemblies of nano to micro elements, e.g., assemblies of aggregated carbon nanotubes. It is also possible to use our vacuum-assisted co-extrusion process to produce hybrid composites comprising the wood pulp fibre and a further rigid fibre, like glass or carbon fibres, and a flexible fibre or fibrillar network, like cellulose fibres or cellulose filaments. The thermoplastic resin can be, but not limited to, polyolefins, like polypropylene or polyethylene, or polyesters, like polylactic acid, or co-polymers, like acrylonitrile-butadiene-styrene terpolymer.

Abstract: Disclosed herein are composite materials comprising a fibrous material and from 1% to 50% of a binding material, by weight of the composite material. Also disclosed herein are methods for making and using the same.

Abstract: Disclosed herein are, for instance, reinforced composites comprising an airlaid mat comprising a natural fiber component; and a resin dispersed within the airlaid mat; wherein the reinforced composite has a natural fiber volume fraction of 20 vol % to 80 vol %, by volume of the reinforced composite. Also disclosed herein are methods of making reinforced composites. For instance, disclosed herein are methods comprising forming a preform comprising: heating an airlaid mat to a temperature of from 40° C. to 200° C., the airlaid mat comprising a natural fiber component and a binder fiber component; and compressing the airlaid mat at a pressure of from 100 psi to 1200 psi; and impregnating the preform with a resin to form a reinforced composite.

Abstract: The present disclosure relates to wood pulp fiber- or cellulose filament-reinforced bulk molding compounds, composites, compositions and methods for preparation thereof. The composition comprises a resin; about 0.5 to about 15 wt. % of a 5 cellulosic reinforcement wherein the cellulosic reinforcement is chosen from wood-pulp fibers, cellulose filaments (CF) and a mixture thereof; and about 30 to about 65 wt. % of a filler.

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.
