Abstract
A process for the preparation of a composite material from a particulate binder material having an average particle size (D9 0) of from 15 to 850 pm and a fibrous material having a density of from 150 to 550 kg/m3, comprising the steps of: a) blending the particulate binder material and the fibrous material, preferably in a weight ratio of 60:40 to 10:90, and b) subjecting the blended material obtained in a) to a curing step under increased temperature and pressure to obtain a composite material. The invention further relates to the composite material thus obtained, and to its use as building materials or as panelling.

A process for the preparation of a composite material from a particulate binder material having an average particle size (D90) of from 15 to 850 μm and a fibrous material having a density of from 150 to 550 kg/m2, comprising the steps of:
- a) blending the particulate binder material and the fibrous material in a weight ratio of 60:40 to 10:90, and
- b) subjecting the blended material obtained in a) to a curing step under increased temperature and pressure to obtain a composite material,
- wherein the fibrous material is obtained by a method comprising:
- A) shredding a car body,
- B) removing at least art of ferrous and/or non-ferrous metal, and
- C) separating the fibrous material from a heavier fraction and a lighter particulate fraction.
A composite material comprising a binder and a fibrous material in a weight ratio of from 60:40 to 10:90, wherein the fibrous material has a density of from 150 to 500 g/m2 prior to incorporation into the composite material, wherein the binder material is a particulate binder having an average particle size (D90) of from 15 to 850 μm prior to incorporation into the composite, and wherein the composite material further comprises a porous polymeric matrix layer.
