EL PRINCIPIO

Un proceso de reciclaje de materiales compuestos reforzados de fibra de carbono

El creciente uso de materiales compuestos reforzados de fibra de carbono en aeronáutica, automotriz, energía… permite vislumbrar una fuerte aumentación de desechos de estos materiales en los próximos años, dentro de un contexto reglamentario que será ciertamente riguroso en materia de exigencia de reciclaje.

Y sin embargo, la valorización de desechos de estos materiales es aún un campo muy poco explorado.

Con el objetivo de posicionarse como un actor principal del reciclaje, Alpha Recyclage Composites consagra una gran parte de sus recursos de los últimos años para actualizarse, a través de una asociación con la investigación académica, un proceso de valorización innovador y eficiente capaz de aportar una respuesta a la problemática dada.

LA SOLUCION

Una tecnología eficiente e innovadora

El proceso de valorización actualmente desarrollado por Alpha Recyclage Composites tiene como base:

- El tratamiento de desechos de composites por la tecnología de la vapo-térmolisis, que ha sido desarrollada durante varios años por Alpha Recyclage Composites y actualmente industrializada bajo una forma adaptada por la sociedad hermana (Alpha Recyclage Franche-Comté) dentro del dominio de la valorización de neumáticos usados;

- El reciclaje de fibras de carbono, obtenidas por la vapo-termólisis, dentro de la fabricación de productos semi-terminados destinados a entrar en la fabricación de composites de segunda generació.

Nuestra tecnología de vapo-termólisis es objeto de varias patentes internacionales. Es el fruto, desde 2009, de una asociación continua con la institución académica (“Institut Clément Ader – Albi”, “Centre RAPSODEE” de la escuela de ingeniería “Mines Albi-Carmaux”) particularmente en el contexto de varias tesis de doctorado.


Los trabajos de investigación y desarrollo, llevados a cabo hasta la fecha sobre la aplicación de nuestra tecnología de vapo-termólisis al tratamiento de composites, ponen en evidencia:


...

Una tasa de eliminación de la resina en las fibras de carbono superior a 99% en masa.

...

Una retención total de las propiedades mecánicas y de la superficie de las fibras de carbono recuperadas, caracterizadas por pruebas confiables.

OBJETIVOS

Una tecnología al servicio de nuestros clientes.

Sectores contemplado

Las empresas productoras de desechos de composites de fibra de carbono trabajando en los sectores de aeronáutica (civil y militar), automotriz, construcción naval y energía.

Desechos

Los desechos de materiales composites reforzados con fibras de carbono, ya sea producto rechazado durante la producción o que se encuentren en su ciclo final de vida.

TRABAJOS

Nuestros trabajos a corto plazo

Fibre de carbone

En el marco de un programa apoyado por los ministerios franceses de Defensa y Economía. Siempre con el apoyo de nuestros socios históricos, consisten en desarrollar e implementar un sistema piloto pre-industrial de vapo-termólisis. Y de forma más general, validar los parámetros de la futura integración al sector industrial de valorización de desechos de composites de fibra de carbono.

Este sistema piloto será puesto en marcha en 2016. El permitirá, de manera operacional y a una escala semi-industrial, tratar desechos de composites, producir cantidades significativas de fibras de carbono reciclado y fabricación de pequeñas series de productos semi-terminados (granulados, esteras, hilos, manga de carbono, mezclados, tejidos…) a partir de fibras recicladas.

ALPHA RECYCLING COMPOSITES opens its capital to accelerate its development

ALPHA RECYCLING COMPOSITES opens its capital to accelerate its development

ALPHA RECYCLING COMPOSITES, an innovative frenchcompany that has developeda recycling process for composite materials based on carbon fiber, announces the entry into its capital of FREYSSINET AERO EQUIPMENT and STS GROUP.

With their knowledge of the aerospace and composite materials sectors, and their industrial know-how, thesetwo partners must accompany ALPHA RECYCLAGE COMPOSITES in the industrialization of its technology.

This fundraising will indeed allow the structure to build a pilot of steam-thermolysisdedicated to the recycling of composites based on carbon fiber. This pilot will have a treatment capacity of 300 metric tonsper year from 2019.

This new phase of development is a continuation of the research work carried out in recent years at the Ecole des Mines in Albi, as part of a joint laboratory. ALPHA RECYCLAGE COMPOSITES has also received the support of the french Defence Procurement Agency (DGA) and the french public investment bank (BPI France).

First anniversary of the joint laboratory with the École des Mines d'Albi: MARVAPOL

First anniversary of the joint laboratory with the École des Mines d'Albi: MARVAPOL

At the end of 2015, Alpha Recyclage, Alpha Recyclage Composites, Armines and Mines Albi reinforced their collaboration and laid the foundations for a joint laboratory: Marvapol. After a year of operation, the results are already at the rendezvous and prospects, many.

On the occasion of the first anniversary of their joint MARVAPOL laboratory, Jean-Louis Pech, Head of ARFC & ARC, and Alain Schmitt, Director of Albi Mines, will present Marvapol, its first results and prospects for the 5 Years to come. A cocktail will be served at the end of the visit.

How to deal with and recycle used tires produced by the automotive industry?

It is this scientific, technological and environmental challenge that is at the heart of the creation of the joint laboratory Marvapol by ARFC, one of the French leaders in tire recycling, and Albi Mines, thanks to the expertise of RAPSODEE, joint research center at Mines Albi, Armines and UMR CNRS 5302 in the area of waste recovery. For recycling, it is necessary to be able to separate and re-use the materials. Until now, ultra-fine particles of carbon black, mainly used as a reinforcing agent in rubber products, were very difficult to isolate and therefore to be recovered.

The method used by Marvapol is vapothermolysis, a heat treatment between 400 ° C. and 800 ° C. in an inert atmosphere under steam. "The process allows valorisation in several forms," says Yannick Soudais, teacher-researcher at Mines Albi, co-chairman of the steering committee and scientific director of Marvapol.

First Results

Since its first steps, the new laboratory has already given rise to two doctoral theses and an industrial research contract. It has already gained international recognition by participating in the European Tire Recycling Association (ETRA) in March 2016 in Brussels and has initiated collaborations with the Academy of Sciences of Prague and the LRCCP (Laboratory for Research and Control of Rubber and Plastics).

Armed with these first results, ARFC and Mines Albi agreed on a research program for the next five years, with a reinforcement of human and material resources and the creation of an instrumented pilot of vapothermolysis. The objective is to develop this process of vapothermolysis and to obtain a better understanding of the physico-chemical phenomena involved in the recovery and reuse of carbon black.

New perspectives

Focused on tire recycling, this research also has applications for the reprocessing of composite materials and carbon fibers. Alpha Recyclage Composites - a sister company of ARFC - is also involved in this joint laboratory process to treat waste from carbon fiber composite materials, using this same vapothermolysis process.


Again, the research expertise of Albi Mines, thanks to the Albigensian component of Clément Ader Institute (UMR CNRS 5312) in the field of composite materials, will be valuable for Alpha Recycling.

Alpha Recyclage Composites to recycle carbon fiber by steam-thermolysis

After several years of academic research in partnership with the Clément Ader Institute and the Mines Albi-Carmaux engineering school, the French SME Alpha Recyclage Composites (member of the Aerospace Valley cluster) has started a development program with the same partners.

Currently the aim of the company is to demonstrate the preindustrial feasibility of steam-thermolysis technology applied to the treatment of waste materials containing carbon fibre, it is also to define the manufacturing process of semi-finished products using recycled fibres and to validate the conditions of re-use of these treated fibres in the manufacture of second-generation composites. This program, which is part of the circular economy logic, is conducted with the joint support of the French Ministry of Defence and the Ministry of Economy and Industry. The areas of application covered by this future industrial sector include civil and military aviation and the automotive sector.
