Aramid Fabric

What outstanding properties do aramid fabrics have?

Aramid fabrics are characterized by their exceptional impact and abrasion resistance. Their high toughness allows for strong energy absorption, making them ideal for use in high-strength laminates or as a protective layer in composite materials. In addition, they offer excellent damping capacity, which reduces vibrations and extends the lifespan of components. Due to their non-flammability and excellent chemical resistance, they are perfectly suited for high-stress composite structures. Depending on the application, a choice can be made between plain weave for high dimensional stability or twill weave for increased flexibility.
 

What are the advantages of aramid fabrics compared to carbon or glass fabrics?

While carbon fabrics offer excellent rigidity and compressive strength, they lack impact toughness. Aramid fabrics, on the other hand, excel due to their extreme toughness and outperform many materials in terms of abrasion and impact resistance. Compared to glass fibers, they are lighter, offer better mechanical load-bearing capacity, and provide superior resistance to chemicals and heat. This makes them particularly attractive for components where a combination of strength, flexibility, and protection is required.
 

In which areas are aramid fabrics used?

Thanks to their outstanding mechanical properties, aramid fabrics are indispensable in aerospace, model making, sports equipment manufacturing, and sandwich construction. They are used in high-strength and thin laminates that need to be both lightweight and durable. In aircraft construction, aramid fabrics improve the impact resistance of components, while in motorsports and sports equipment manufacturing, they provide impact-resistant composite structures. Aramid fibers are also used in shipbuilding and boat construction to create abrasion-resistant exterior structures.
 

Which weave structure of aramid fabrics is optimal for which application?

The choice of weave structure affects the processing properties and mechanical performance of aramid fabrics. Plain weaves offer high dimensional stability, are resistant to deformation, and are especially suitable for structural composite components. Twill weaves, on the other hand, provide better drapeability, making them ideal for complexly shaped or sandwich structures. When combined with carbon fibers as hybrid fabrics, specific properties like impact resistance and compressive strength can be tailored and optimized.
 

How can aramid fabrics be processed effectively?

Processing aramid fabrics requires specialized techniques, as they are more difficult to cut and handle compared to carbon or glass fabrics due to their high fiber toughness. For precise cutting, special cutting tools or laser systems are often used. In composite materials, they can be ideally combined with epoxy resins to produce high-strength components. By combining them as hybrid fabrics with carbon fibers, custom material solutions for composite applications can be developed that combine rigidity, toughness, and abrasion resistance in an optimal way.
