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.
Initial demonstration in furniture shows properties two to nine times higher than plywood, OOA molding for uniquely shaped components.
Fresh from the IACMI's recent Detroit conclave, CW editor-in-chief Jeff Sloan notes the attendees' admirable commitment to ensure that the carbon fiber composites we build today will be recyclable tomorrow, but asks who will be there, as those products reach end of life, to buy and reuse those reclaimed materials?
CW technical editor Sara Black reports on the what some of the composites industry's leading recycling thinkers have to say about carbon fiber reclamation and re-use.
Earlier this year I wrote an article on composites recycling and one of the things that struck me was how little fiberglass composite waste was being recycled.
The HiPerDiF (High Performance Discontinuous Fibre) project is exploring an alternate way of producing high-performance carbon fiber composites: start with discontinuous, rather than continuous fibers.
JIm Stike, of Materials Innovation Technologies – Reengineered Carbon Fibers (Fletcher, N.C.), points to progress in the reclaiming of waste and end-of-life carbon fiber.
Teijin’s carbon fiber/thermoplastic material, used in the CarbonPro pickup box, was developed with CO2 reduction in mind.
The JEC Group has announced the winner for each of the 11 Innovation Award categories. Learn more about the winners and their projects at JEC World 2024.
Williams new EV platform demos 223 composite forming process and £20 suspension arms using recycled carbon fiber.
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.
