This lightweight Griffin sports car body panel prototype uses a combination of ELG's Carbiso-M recycled carbon fiber, woven carbon fiber fabric and resin infusion technology
The state of recycled carbon fiber is a complex one, and the industry is built on the hope of solving the problem, that is, keeping the disposal of carbon fiber waste out of landfills and filling the carbon fiber supply and demand gap
.
According to general estimates, about 30% of carbon fiber ends up as waste, and because the valuable material ends up in landfill, most analyses agree that the annual demand for this material may exceed the current annual demand in the next few years.
yield
.
According to the estimates of Brett Schneider, president of global fiber at Hexcel, and Dan Pichler, president of CarbConsult in Germany, the average estimated value of global carbon fiber demand is about 65,000 to 85,000 t per year, while the global rated capacity (more than the actual capacity) is about 150,000 t
.
And commercial suppliers of recycled carbon fiber point out:
► Recycled and reused materials can be a potential solution to this supply-demand gap
.
► The recycled carbon fiber industry has its own challenges: Although the recycling technology of carbon fiber composites has existed for many years and can produce products with mechanical properties very close to virgin materials, the composite recycling industry is relatively young, and the recycling of recycled materials As far as carbon fiber is concerned, it is still in the early stages of market development
.
► As confidence in the quality of fibre produced by recycling manufacturers increases, questions about cost and availability are on the agenda
.
"The technology does exist, and it's been around for quite some time, but the supply chain hasn't been audited
," said Andrew Maxey, CEO of Vartega in the United States, "while you can have the best in the field without the right mix.
Commercial suppliers often look to the aerospace industry as a source of production waste and use end-of-life materials as recycling materials
.
However, despite the large amount of production waste generated by the aerospace industry going to landfill, many OEMs and manufacturers are reluctant to use it as a stable source of material for high-volume product lines
.
On the other hand, some progress is being made
.
In December 2018, Boeing announced that it would supply cured and uncured carbon fiber waste to specialist carbon fiber recycling company ELG Carbon Fibre Ltd (ELG) in the UK for recycling and reuse in the production of other composite materials.

The agreement is the first formal material supply relationship established between a carbon fiber recycling company and a major aircraft OEM, which seems to bode well for the industry
