Composite materials are engineered combinations of two or more distinct materials, merging their individual properties to create a new material with enhanced characteristics. Typically composed of a reinforcing phase (like fibers or particles) embedded within a matrix (often a polymer, metal, or ceramic), composites leverage the strengths of each component to achieve superior strength, stiffness, lightness, or other desirable attributes. Their versatility extends across industries, from aerospace and automotive to construction and sports equipment, where their tailored design and exceptional properties offer solutions for high-performance applications.
Recycling in composites manufacturing is an evolving endeavor aimed at addressing sustainability challenges. Unlike traditional materials, composites often pose recycling complexities due to their multi-component nature. However, innovative techniques are emerging to tackle this issue. Methods like pyrolysis, mechanical recycling, and chemical processes are being developed to efficiently recover valuable components from composite waste, such as fibers or matrix materials.
Life cycle assessment (LCA) will aid in calculating carbon emissions for all of its carbon fiber filament applications.
Upon his one-year anniversary as editor-in-chief of CW, Scott Francis looks back at some of the brand’s changes and hints at where it might be heading next.
R&D project by CG Rail explores use of carbon fiber-reinforced thermoplastics and recycled manufacturing scrap to meet fire safety, weight and volume targets.
Clean Sky 2 HELACS project aims to enable improved recycling of composite components at aircraft end of life.
Austrian research institute Wood K plus makes 95% silicon carbide ceramics more sustainable (>85% bio/recycled content), enables 3D shapes via extrusion, injection molding and 3D printing.
Study is critical to understanding the impact of low-carbon concrete and advanced composite reinforcement systems in the construction sector, and its contributions toward low-carbon emissions, structural performance and EOL recycling.
€8.6 million has been raised so far to industrialize a proprietary technology to save 4,000 tons of recycled material annually and repurpose it into value-added products.
CW technical editor Hannah Mason recaps some of the technology on display at JEC World, including natural, bio-based or recyclable materials solutions, innovative automotive and renewable energy components and more.
When used with composite reinforcements, EzCiclo can be recycled and degraded via the company’s CleaVER recycling technology with waste elimination and a final fiber with equivalent virgin fiber mechanical performance.
With fiber weight fractions of up to 50% and an array of thermoplastic matrices available, injection molding compounds are expanding composites’ capabilities.
