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.
A research program in the U.K. is attempting to achieve a fundamental step-change in the composites industry.
A process that combines continuous carbon fiber-reinforced PAEK with chopped fiber/PEEK overmolding is making inroads in the aerospace market. Parts that previously could not be produced cost-effectively from composites can now be made at less cost than their metal counterparts.
Reps from the composites industry recently spoke at The Plastics Recycling Conference about the potential opportunities in this sector.
Mass production of automotive composites, recycling and composites in shipbuilding are just some of the themes from this year’s JEC.
Vartega Inc. (Golden, CO, US) and Sojitz Aerospace Corp. (Tokyo, Japan) will be jointly exhibiting Vartega’s novel carbon fiber recycling technology and materials at the upcoming CAMX 2017 trade show and conference.
Demand for advanced fiber, virgin and reclaimed, is on an upswing after a dip during the recent recession. Fiber suppliers are gearing up to meet an expected increase in demand as manufacturers in a number of composites end-markets scale up or start up part development and production programs
CW reflects on this year’s CAMX, the current state of the composites industry and looks ahead to 2024.
Collins Aerospace draws on global team, decades of experience to demonstrate large, curved AFP and welded structures for the next generation of aircraft.
There is a generation of wind turbine blades at or near the end of their useful life. Disposing of them, recycling them or reusing them requires a better understanding of the blade end-of-life landscape.
EU-funded MORPHO project will use embedded sensors, data-driven hybrid twins and machine learning to increase RTM yield, improve damage-tolerant design, achieve SHM and 100% recycling.
