Carbon fibres & resin-matrix composites

Carbon waste streams are not all the same. Some consist of long fibres, bobbins, unidirectional tapes or prepregs that still carry high material value. Others are cured carbon / resin laminates, where the fibre is locked inside a polymer matrix. XCRUSHER addresses both situations: revalorising long fibres when the feedstock allows it, and deconstructing carbon / resin composites to produce reusable carbon fractions.

Two families of carbon streams

1. Long carbon fibres, bobbins & prepregs

Carbon production waste may take several forms: bobbins, spools, unidirectional tapes, prepreg production scrap, carbon / resin scrap before curing or end-of-lot material. These streams should not be treated as simple waste to be shredded. Their value depends on fibre continuity, length, surface state, possible impregnation and the ability to bring them back into a usable form. XCRUSHER has been applied to these streams to revalorise long carbon fibres and produce reusable fibre formats depending on the initial state of the material.

2. Carbon / resin laminates

Cured carbon composites raise a different challenge: the fibre is immobilised inside a resin matrix. In this case, the objective is not to preserve a continuous textile-format fibre, but to deconstruct the laminate, open fibre / resin interfaces and produce valuable carbon fractions. Depending on the feedstock and the protocol, the material can be directed towards short fibres, liberated fibres or carbon-fibre powders for reinforcement, formulation, compounding or functional-filler applications.

The industrial bottleneck

Carbon-fibre recycling is difficult because material value strongly depends on form. A long fibre, a short fibre, carbon-fibre powder and a cured composite do not address the same markets or the same qualification requirements. Conventional mechanical shredding may unnecessarily destroy fibre length, mix fibre and resin, or produce material that is difficult to requalify. The bottleneck is therefore not only to "recover carbon". It is to produce the right carbon format for the right downstream route.

The XCRUSHER approach

XCRUSHER acts as a physical separation and deconstruction technology. For long fibres, bobbins or prepregs, the objective is to preserve as much fibre value as possible and prepare a usable reformatting route. For carbon / resin laminates, the objective is to deconstruct the matrix, liberate the fibre and prepare adapted carbon fractions: short fibres, liberated fibres or carbon-fibre powders. XCRUSHER is therefore not positioned as a simple grinder, but as a physical transformation platform capable of directing carbon material towards different revalorisation formats. Available visuals will illustrate both routes: reformatting of long fibres / bobbins, and deconstruction of carbon-resin laminates into short fibres or carbon powders.

What XCRUSHER brings

Long-fibre revalorisation

Preparing carbon fibres from bobbins, spools, tapes or prepregs for usable reformatting.

Controlled fibre formats

Directing material towards bobbins, fibre formats or areal weights adapted to downstream routes.

Laminate deconstruction

Opening fibre / resin interfaces in cured carbon composites.

Fibre / resin separation

Reducing fibre / resin association to obtain better-differentiated fractions.

Short fibres & carbon powders

Producing valuable carbon fractions as short fibres, liberated fibres or carbon-fibre powders depending on the feedstock.

Preparation for downstream uses

Preparing material for compounding, reinforcement, formulation, functional fillers or other reincorporation applications.

Examples of materials: carbon-fibre bobbins · carbon spools · unidirectional tapes · prepreg production scrap · carbon / resin scrap before curing · carbon / resin laminates · cured carbon composites · short carbon fibres · carbon-fibre powders.

Positioning: XCRUSHER brings an industrial reading of carbon recycling: value is not only in the fibre, but in the recovered format. Depending on the stream, the objective may be to preserve a long fibre, reformat material into bobbins, deconstruct a laminate or produce a usable short or powder carbon fraction.

Each carbon stream must be assessed according to its initial form, impregnation state, resin chemistry, curing level, fibre length and targeted downstream route. XCRUSHER does not claim automatic equivalence with virgin fibre or direct qualification for critical applications without downstream validation.
