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.
Starting with the sporting goods and bicycle market, French startup 3DiTex targets its continuous preforming system for thermoformable, thermoplastic composite tubes in complex geometries.
The Center for Composite Materials (CCM) at the University of Delaware introduced at JEC a new fiber-based product called TuFF (Tailored Universal Feedstock for Forming).
Announced at Nova-Institute’s Biocomposites Conference in Cologne, Germany, the winning entries use natural fiber composites for automotive and consumer goods applications.
Sustainability requirements are driving more companies to conduct LCAs to evaluate the environmental impact of their products and processes. Tools and research in this area continues to evolve.
Use case applications with Helicoid technology implementation demonstrated mechanical performance improvements, such as impact resistance and strength.
Preconsolidated carbon fiber/PPS and PEEK and automated thermoforming enable six-figure production of connectors for the Airbus A350 XWB.
