Definitions
- the present invention also concerns novel nanocellulose composites.
- the present method provides for manufacturing of the reinforcement directly in the would-be composite. Expensive and energy intensive drying of any aqueous dispersion, as conventionally called for, is avoided. Agglomeration of the nanocellulose during such a drying process can also be avoided. There is no need for manual hand lay-up processing related to long- fibre composites by using the present technology of nano-scale reinforcement of the composites. There will be formed a strong cross- linking of the cellulosic fibres to the polymer matrix, based on covalent bonds between the components.
- thermoset resins using pearl mills or basket mills.
- a suitable raw-material such as macroscopic cellulose, for the target nanocellulose material, is combined at a
- the nanocellulose can be synthesised from various cellulosic materials, such as wood, agrofibres, such as annual plants, and food production side-streams.
- the liquid dispersion can be heated to lower the viscosity and to enhance the process.
- the heating can be carried out before addition of the raw-material, in practice the cellulose material, or during the addition or at intervals between additions of the raw-material.
