A METHOD AND A SYSTEM FOR MANUFACTURING A PRODUCT OF NATURAL FIBRE COMPOSITE, AND A PRODUCT OF NATURAL FIBRE COMPOSITE

摘要

The invention relates to a method for manufacturing a product (1 ) of natural fibre composite, the method comprising preparing a raw material mixture (4) which comprises at least 60 wt-%, advantageously at least 80 wt-% of natural fibres, and 1 to 40 wt-%, advantageously 10 to 20 wt-% of a binding agent. The method further comprises bringing said raw material mixture (4) in connection with a manufacturing mould (2), the manufacturing mould comprising a first surface (2a) and a second surface (2b). Subsequently, a blank (3) is formed of said raw material mixture (4) onto the first surface (2a) of said manufacturing mould (2), the blank substantially having the shape of the product of natural fibre composite to be formed, the forming of the blank (3) of the raw materials (4) taking place by the effect of a pressure difference across the manufacturing mould (2) in such a way that the pressure is substantially greater on the side of the first surface (2a) of the manufacturing mould than on the side of the second surface (2b) of the manufacturing mould. The method finally comprises finishing the blank (3) as a product (1 ) of natural fibre composite. The invention also relates to a corresponding system and a product of natural fibre composite.
