Abstract
Method for obtaining a second raw material from composite material waste, based on mechanical techniques that allow the structure of the composite material waste to be broken and to be able to reuse a first fibre-resin composite material, with or without a core material, in a formulation to obtain said secondary raw material.
Claims13
A secondary raw materials obtaining method from composite materials structures waste with at least fibre-resin composite material and core material, characterised in that it at least comprises the following steps:
- a) At least one first ripping of the composite materials structures waste,
- b) Densiometric separation of the composite materials structures waste into a first composite material with at least fibre-resin and into a second core material,
- c) At least one shredding of the first composite material,
- d) At least one first sieving of the shredded first composite material with at least fibre-resin, separating said material into at least two fractions of different sizes, a first fraction smaller than 1 mm and a first fraction larger than 1 mm,
- e) Micronizing the first fraction larger than 1 mm to obtain a micronized composite material fraction smaller or equal to 1 mm,
- f) Mixing the first fraction smaller than 1 mm with the micronized composite material, and
- g) Reformulating the previous mix with at least one compound to obtain a secondary raw material.
