From high-speed race cars to cutting-edge aircraft, epoxy resin and carbon fiber are the secret ingredients powering innovation across industries. In applications where every ounce counts and resilience is non-negotiable, carbon fiber reinforced with epoxy resin is the go-to choice.

Let’s explore how this perfect match redefines what’s possible in strength and durability.

Epoxy Resins for Carbon Fiber

Composites are specialty materials made from a combination of fibers and resins. Epoxy resin is a thermoset polymer material that is heated and cured to chemically alter the material’s composition to create a permanently hardened substance. Epoxy resins can have glass transition temperatures above 400F˚, allowing them to retain their physical properties in high-temperature ranges. Once the liquid polymers in an epoxy resin solidify, the hardened piece becomes strong, resistant to chemical and thermal damage, and can withstand physical wear or impact.

Epoxy resin is advantageous due to its properties in its cured state. The material has the unique ability to fuse with carbon fibers to create an even stronger microstructure that showcases the advantages of both the epoxy and the fibers.

Carbon fibers are strong, lightweight, and fatigue-resistant fibers used to build composite materials. By combining carbon fibers with epoxies, manufacturers can create incredibly hard, durable materials that outperform both individual material types. Composites are a relatively new production material compared to materials like aluminum, iron, and steel, but there are many benefits to working with carbon fiber-strengthened composites that span a range of industries.

Carbon fibers resist fatigue, have low thermal expansion, and absorb or dampen vibrations. They are supplied in two forms that are suitable for creating composites. Carbon fiber tows are bundles of thousands of untwisted, continuous fibers that can be used directly in epoxies or converted into woven reinforcement materials like fabrics or tape.

Benefits of Epoxy Resins for Carbon Fiber

Epoxy resin and carbon fiber composites are uniquely strong and offer excellent performance in commercial and industrial applications. Some of the benefits of this material include:

  • Strength: Carbon fibers have high tensile strength but are prone to damage. Epoxy resins have low tensile strength, but their toughness and malleable properties protect the fibers from damage, creating an even stronger material.
  • Lightweight: The composite material has an excellent strength-to-weight ratio, surpassing even aluminum and titanium. As a result, manufacturers can produce lightweight parts that can be used in more energy-efficient vehicles and assemblies.
  • Flexibility: Despite its strength and durability, the composite is simultaneously very flexible. This means the material can withstand strong impact forces by absorbing the force. It also won’t develop spider cracks under impact or when the material is bent.
  • No shrinkage: Epoxy resins won’t shrink after curing. This extends the lifespan of composite parts and components used in harsh environments.
  • UV resistance: The composite material can withstand exposure to sunlight. It’s 100% UV resistant, so it can be used in long-term outdoor applications without the risk of wear or degradation.
  • Aesthetics: Epoxy resin and carbon fiber composites are transparent, which makes them an excellent choice for visible components and consumer-facing products.
