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.
Applications and enabling technologies for carbon fiber promise new market penetration – challenges notwithstanding.
The New York-based startup recently partnered with a wind blade recycling company and plans to produce its first full-scale prototypes this year.
Recycled polycarbonate composite material is blended with new polycarbonate, offering similar properties to virgin materials, saving raw material resources and contributing to the circular economy.
History and future developments for high-performance boron fiber.
The investment will help fully commercialize the company’s Red Series software tools, 3D printer and molding equipment to lead the way in the production of sustainable, high-performance CFRTP parts for end-use applications.
Though its recent SuperTruck project used CFRP to slash over 3,200 lb, Volvo says it needs lower cost materials like recycled carbon fiber.
Collaboration with the School of Engineering at the University of Plymouth looks at the effect of pre-processing and post-processing techniques on low-carbon materials.
The matrix binds the fiber reinforcement, gives the composite component its shape and determines its surface quality. A composite matrix may be a polymer, ceramic, metal or carbon. Here’s a guide to selection.
Alex Edge, sales and business development manager for recycler ELG Carbon Fibre (Coseley, U.K.), says his company’s recycled carbon fiber (RCF) products can offer from 30 to 40 percent cost savings vs. virgin carbon fiber (VCF). Tim Rademacker, a managing director at competitor CFK Valley Recycling (Stade, Germany) cites savings of 20 to 30 percent.
Interdisciplinary project utilizes biomaterial waste for sustainable composites development to produce resilient buildings with a low carbon footprint.
