The best Composite Bonding Adhesives you need to know

Adhesive bonding is a common bonding process that is widely deployed in the industry for the assembly of composite compounds.

 

What are composite materials?

Composite materials involve the combination of various materials to create a new material with superior qualities. The new material usually possesses better properties than the individual components. Many composites are used in various industries to produce products that have desirable properties. When they are made, composites usually result to getting strong and lightweight parts that are highly resistant to corrosion. Composite bonding adhesives are used to make composite materials. You can easily create complex shapes by bonding two different composite materials. With the use of the right composite bonding adhesives, the process is usually easy and quick. Composite bonding adhesives are used to glue dissimilar materials to produce a composite material.

An overview of composite bonding adhesives

Engineered adhesives are used for bonding composites in industrial settings. Due to the wide range of applications, there are various composite bonding adhesives. Some of the most common types of composite bonding glues are UV cure adhesives, acrylic adhesives, polyurethane adhesives, epoxy adhesives, and cyanobacteria. In industrial environments, there are usually debates as to which one of these adhesives is the best when executing composite bonding. To choose the best option, you will have to consider the nature of the composite material, the bonding requirements, as well as the chosen assembly process. When it comes to the best composite bonding adhesives, several options can be used in the industry.

 

The best types of composite bonding adhesives

Various composite bonding adhesives are considered the best when it comes to the right applications. There are various composite bonding adhesives such as:

Epoxy adhesives: When it comes to bonding composites, the most common industrial glues used are epoxy adhesives. There is the one-part epoxy adhesive that is heat-curable giving many composite materials very high-strength bonds. After the application of the adhesive, the material is jigged or clamped to ensure proper alignment as the adhesive dries off. This is done as the material is moved to the oven as well as during the entire heat cure cycle. As soon as it has cooled sufficiently, the clamps are loosed for the assembly to be painted. There is also the two-part epoxy adhesive that cures at room temperature. They have very high-strength bonds and offer more versatility.

 

Structural Acrylic:: Structural acrylic is another exceptional composite bonding adhesive. On application, it usually forms a bond with a very high strength to form composite materials. There are many variants of acrylics used for composite bonding. Most of these glues have fast setting times and can achieve sufficient strength to be handled in as little as 4 minutes. This option has exceptional gap-filling properties which makes them suitable for bonding materials with rough surfaces. These types of composite adhesives are known to provide high peel strengths and bonds with high strength. There are several types of structural acrylics:

Methyl methacrylate and the surface-activated structural acrylics.

 

Cyanoacrylates: Cyanoacrylates are also used in industrial applications as composite bonding adhesives. These types of adhesives are also called instant adhesives. They can quickly create very strong bonds in environments that do not need high peel or impact resistance. The cyanoacrylate can also be used for the assembly in place of clamps or jiggs while the two-part composite adhesive cures.

 

Urethanes: Urethanes can be applied to work on general composite bonding projects because of their very strong bonds. They are very similar to epoxies and can be used on general applications that need flexible bonds.

 

Polyurethanes: There are composite bonding adhesives that are recommended for bonding very big composite panels. The two-part polyurethane adhesives are useful to work in this case. It can be used to bond two different composite car panels that form the car bonnet. Polyurethanes have very wide application areas.

 

UV curing adhesives: Composite bonding adhesives like UV curing adhesives work effectively when they are used to bond glass or plastics to composite panels.

 

Applications of composites

Composite bonding adhesives can be applied in different industries to form formidable materials. It can be applied in the following applications:

• Railway:Used in platforms, track beds, and interiors.
• Architecture: Used in tubes, windows, and roofs.
• Energy:Used in oil risers, fuel cells, and turbine blades.
• Marine: Used in bows, keels, and interior mouldings.
• E-mobility and automotive: Used in brakes, frames, and body panels.
• Chemical: used in water treatment apparatuses, tanks, and pipes.
• Aerospace: used in cryogenics, fuselages, and in wings.

Bonding Composite Materials

Composite materials usually need a delicate bonding technique. This means that mechanical or welding fastening processes are traditional bonding processes that will compromise the strengths of the composite materials. This means that the use of composite bonding adhesive can be used to create the most desirable results. This is why it is widely applied in the rail, wind, automotive, and aerospace industries. Bonding composite adhesives come with excellent mechanical properties such as:

Bonding dissimilar substrates: The use of composite bonding adhesives can be used to bond two dissimilar substrates together

Faster production: With composite bonding adhesives, you can easily produce your goods faster. This faster production means more revenue and faster operations.

Improved durability: Composite bonding adhesives can be used to improve the durability of the bonds.

Lightweight product: The use of adhesives to bond composite materials helps reduce the total product weight significantly. This is different from using mechanical fasteners or bolts which add a significant amount of weight to the final product.

Improved aesthetics: The use of adhesives to bond composites means that you can easily style the material without affecting its final appearance. The use of mechanical fasteners and bolts does not help improve the aesthetics of the final product.

Strong bonds: Composite bonding adhesives are engineered glues that are used due to their high strengths. They usually produce durable bonds that can withstand extreme environments.

Even load distributions: Bonding composites with adhesives usually help dissipate the loads in both materials.
