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.
BioHome3D, made of wood fibers and bioresins and entirely 3D printed, highlights Maine’s effort to address the need for more affordable housing.
The partnership will accelerate new recycling technologies, such as delivering a series of R&D projects, investing in new material feedstocks and more.
CW editor-in-chief Jeff Sloan returns from Carbon Fiber 2015 in Knoxville TN, US, with news that carbon fiber demand will outstrip supply by 2020, prompting expansion in the 2018-2019 timeframe that could include sources in China.
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.
The carbon fiber-reinforced biocomposite sandwich panel features a 100% recycled foam core and has been designed for light weight and fire resistance.
Prodrive Composite chief engineer John McQuillam discusses the company’s primary to tertiary (P2T) carbon fiber composite recycling process.
For its new battery-electric iX sports activity vehicle, BMW combines CFRP strategies from previous i3, i8 and 7-Series designs and adds CFRTP for a lightweight, rigid frame.
The PA6-based products feature waste glass in loadings of 30, 35 and 60%. Lanxess is shifting to a circular economy to help improve the company’s carbon footprint.
An Airbus-led team characterizes RCF veils and shows their ability to best glass fiber composite sidewalls in cost, weight and surface finish.
Annual award honors advancements in reducing the carbon footprint, mitigating water and energy consumption, promoting material reuse and recycling and applying composites for lightweighting.
