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 new sustainable prepreg material is made using recycled carbon fiber prepreg waste, is drapeable and can be easily handled.
The NCC begins a three-year program to rapidly refine and scale industry continuous carbon fiber recycling, a key solution to net-zero ambitions. Partner collaborations are welcomed to the effort.
Skeptics say it won’t work — Osaka-based Microwave Chemical Co. says it already has — and continues to advance its simulation-based technology to slash energy use and emissions in manufacturing.
Regen Fiber’s sustainable recycling process keeps wind blades out of landfills by converting them into raw materials for use in asphalt, composite products and more.
Simultaneous certification for bio-based and circular raw materials continues Teijin’s commitment to the circular economy. Commercial production to begin in first half of 2024.
As companies strive to meet zero-emissions goals, evaluating a product’s carbon footprint is vital. Life cycle assessment (LCA) is one tool composites industry OEMs and Tier suppliers are using to move toward sustainability targets.
With 840,000 tonnes of composites waste looming on the horizon, Australian researchers have discovered a recycling approach with increased material recovery and improved energy efficiency.
A look at the process by which precursor becomes carbon fiber through a careful (and mostly proprietary) manipulation of temperature and tension.
Automotive and filament winding experts at Voith Composites showcased their Type IV hydrogen storage tanks at JEC 2023. These 350-liter pressure vessels, manufactured with recycled carbon fiber, are primarily designed for heavy-duty vehicles.
Automated fiber placement develops into more compact, flexible, modular and digitized systems with multi-material and process capabilities.
