carbonreinforced

Carbonreinforced or carbon reinforcement refers to materials in which carbon-based fibers or fillers provide structural reinforcement, typically in composite materials such as carbon fiber reinforced polymers (CFRP). It also encompasses carbon-reinforced cementitious composites used in construction. The term is used in industry to denote reinforcement with carbon of varying forms, including continuous fibers, woven fabrics, or short fibers.

Composition and manufacturing: The most common carbon fibers are PAN-based or pitch-based; embedded in matrices such as epoxy, polyester, vinyl ester, or thermoplastics like PEEK. CFRPs are typically produced by layup, resin infusion (VARTM), autoclave curing, or prepregs; cementitious CFRC uses carbon fibers in cementitious matrices via mixing, bonding, or impregnation methods. Quality depends on fiber volume fraction, fiber orientation, and resin cure.

Properties: High specific strength and stiffness; excellent fatigue and corrosion resistance; low density and low coefficient of thermal expansion; anisotropic behavior; carbon fibers are strong but relatively brittle; matrices influence impact resistance and damage tolerance; processing costs are high; recyclability limited.

Applications: Aerospace, automotive, sporting goods, wind turbines, marine, and civil engineering components; CFRC used to retrofit structures; carbon fibers used as reinforcement in concrete in high-performance applications.

Variants and challenges: Carbon nanotube or nanoengineered reinforcements; CFRP versus CFRTP; environmental impact and end-of-life concerns; ongoing research to improve recycling and repair; regulatory and safety considerations.
