Carbon is an expensive but very versatile material that can withstand high loads and is therefore not only used in industry, but increasingly in the hobby sector as well. However, there are a few things to consider when bonding carbon, which we will explain to you below. We will also explain how to use certain adhesives for carbon bonding.\u00a0<\/strong><\/p>\n

What Is Carbon (CFRP)?<\/h2>\n

Carbon is also known as carbon fiber reinforced polymer (CFRP). It is a composite material made of carbon fibers with a plastic matrix that fills the spaces and bonds the fibers together. This combination creates a material that is expensive but extremely versatile, lightweight and incredibly strong, and can be used for a wide variety of projects.<\/p>\n

As a rule, a resin, in particular epoxy resin<\/a><\/strong>, serves as the matrix. Various other thermoplastics and thermosets can also be used as the matrix. The resin gives the carbon its stability; the materials virtually interlock with each other and thus become particularly resistant to external influences. The fibers and matrix are laminated in both transverse and longitudinal directions to achieve the most durable and stable structure possible.<\/p>\n

Carbon can be joined in various ways, but in principle, only bonding is advisable. This joining technique is not only less time-consuming than all other methods, it also does not lead to a weakening of the structure (as is the case with riveting or screwing, for example).<\/strong><\/span><\/p><\/blockquote>\n

Applications for Carbon (Reinforced Plastic)<\/h2>\n

CFRP is used wherever materials are exposed to high loads. A high level of stiffness is required from the material. The many advantages of the material outweigh the disadvantage of its very high price.

Nowadays, carbon is used:<\/p>\n

    \n
  • <\/i> As a progressive material in the automotive and aircraft industries;<\/strong><\/li>\n
  • <\/i> As a light and easily adaptable, but at the same time very stable, material in boat-building;<\/strong><\/li>\n
  • <\/i> As a material in wind turbines, especially in offshore operation;<\/strong><\/li>\n
  • <\/i> For road bikes to make them more stable and reduce their weight;<\/strong><\/li>\n
  • <\/i> For professional tennis rackets;<\/strong><\/li>\n
  • <\/i> In the hobby and crafts sector.\u00a0<\/strong><\/li>\n<\/ul>\n

    Important Points to Consider When Gluing Carbon Fiber<\/h2>\n

    CFRP bonding presents some challenges to the user, but these are surmountable. You should pay attention to the following points:<\/p>\n

      \n
    • <\/i> The carbon adhesive used must be low-shrinkage<\/strong> for CFRP bonding to succeed.<\/li>\n
    • <\/i> The thickness of the adhesive layer<\/strong> should be as uniform as possible.<\/li>\n
    • <\/i> Adhesives that ooze out must be avoided<\/strong> or removed immediately.<\/li>\n
    • <\/i> The conditions under which the adhesive seam cures must be constant.<\/strong> For example, there must not be any high temperature or pressure differences.<\/li>\n
    • <\/i> It is essential to pay attention to the thermal expansion behavior<\/strong> when bonding different materials, otherwise stresses will arise in the material that can lead to fractures or weakening.<\/li>\n
    • <\/i> The curing temperature should be kept low,<\/strong> otherwise the outer shell could be subject to thermal damage.<\/li>\n<\/ul>\n<\/div>\n

      Carbon Fiber Adhesive Recommendations<\/h2>\n

      The best adhesive for carbon fiber can be found either in epoxy for carbon fiber or in carbon glue. We will discuss these two adhesive options in detail below, including the top-recommended product for each.<\/p>\n

      Epoxy for Carbon Fiber<\/h3>\n

      An epoxy adhesive consists of two components that, once mixed, trigger a chemical reaction. A two-component epoxy-based adhesive forms extremely stable and durable bonds with a wide variety of materials. It also scores with many other advantages, which we will discuss below.<\/p>\n
