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.
The flax fibers meet strength and stiffness requirements while reducing vibration, cost, enhancing safety and lowering its CO2 footprint by 75%.
The carbon fiber RTM press will be installed at the CSP facility in Palmela, Portugal in order to run the company's first commercial applications using this technology.
Prodrive Composite chief engineer John McQuillam discusses the company’s primary to tertiary (P2T) carbon fiber composite recycling process.
Continuous fiber 3D printing using epoxy, vinylester and acrylic with continuous glass, carbon, basalt and other fibers, including deposition along nonlinear curves, is only the beginning.
Geoff Wood, founder, fellow and vice president of innovation at the Composites Recycling Technology Center (CRTC) in Port Angeles, Wash., discusses CRTC, the composites recycling market and more. Geoff will be moderating a panel on composites recycling at CompositesWorld’s Carbon Fiber conference Nov. 28-30 in Charleston, South Carolina.
The carbon fiber-reinforced biocomposite sandwich panel features a 100% recycled foam core and has been designed for light weight and fire resistance.
ThermoPRIME and Thermosaïc technologies recycle plastic and composite waste via modular, flexible equipment.
Designers are invited to submit a product, part, or concept that uses KyronMAX’s range of high-strength, carbon fiber-based composites for a $25,000 prize and prototype development support.
Although CW’s coverage of composites recycling dates back over a decade, informal statistics still show that only ~2% of composites-related companies are active recyclers. That said, three years since our most recent feature on the subject, there is demonstrably greater interest and activity, and real applications of recycled fiber are growing.
Sany reports that it has adopted an optimized airfoil design with greater thickness and a blunt trailing edge to augment strength and stability.
