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.
Recovered benzoic acid from CFRP matrix breakdown can be “consumed” by genetically modified fungi, enabling high-value reclamation of both the fiber and the matrix.
Fully cured thermoset resin solubilizes on demand and under benign conditions, allowing for up to 100 wt% recovery of fibers in composites, including carbon fiber. The circularity is driven by a bio-based alternative to BPA.
Fully recyclable, race-ready carbon fiber/epoxy mirror housing component using Holy’s IPT technology highlights track-proven durability, paves way for future motorsport components.
Dallara and Tenowo collaborate to produce a race-ready Formula 2 seat using recycled carbon fiber, reducing CO2 emissions by 97.5% compared to virgin materials.
Researchers, led by Vipin Kumar, developed a low-cost, recyclable carbon fiber wind turbine blade tip that showed resilience to high-voltage lightning strikes, with more innovations in store.
Fire-retardant recycled carbon fiber nonwoven prepreg was developed with aircraft interior programs and other FST-focused applications in mind.
Development and integration of recycled composite ballast dorade vents for an IMOCA class yacht and other ongoing projects demonstrate a push for greater circularity in the marine industry.
CDCQ, LxSim, Addcomp and Argon 18 collaborate to optimize a carbon fiber/PA6 bike seat post, democratizing AFP and demonstrating materials and process for future designs and production.
Infinity project developed highly oriented rCF/PA6 tapes with 88% the tensile strength, modulus of a virgin CFRP product and 49-66% reduction in global warming potential.
Multimillion-dollar investment to drive next-gen automated RTM technology will open new applications and markets for composites OEMs.
