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.
Elevated Materials makes its mission to deliver reclaimed high-quality aerospace carbon fiber to a variety of industries.
CW senior technical editor Ginger Gardiner discusses some of the developments and demonstrators shown at the industry’s largest composites exhibition and conference.
Eco-friendly resin system using glycol lignin offers an eco-friendly option for CFRP structures and components, and core materials.
Japan’s premiere single-seater race series confirms hybrid composite parts for SF23 chassis as part of Next 50 plan.
Breakthrough recycling of excess aerospace carbon fiber diverts up to 1 million pounds of waste company-wide.
Scientists from Japan develop cellulose nanofiber-carbon fiber composite films with high in-plane heat conductivity to assist in heat dissipation in electronic devices.
Vestas seeks areas where local recycling infrastructure is robust, and customer demand can be established. Recycling methods can include cement co-processing, gasification, development of new composite materials and reclamation.
Recycling uncured and cured carbon fiber was once a challenge, but that hurdle has been cleared. The difficulty we have now is in developing a market for what has become a mountainous amount of recycled material. CW's Carbon Fiber 2016 conference will address this issue.
“Innovation in Materials” award recognizes successful continuous fiber reclamation and reuse for a composite hydrogen tank.
Reseachers obtained a reduction in costs and energy consumption through the manufacture of three composite prototypes and confirm the feasibility of recycling and processing the resulting material.
