Composite Wear Resistance

Function as well as Finish
Composite wear is critical in applications such as industrial roll coverings or friction product substrates where the speed of operation can impact durability. Aramid is a high performance synthetic material which exhibits excellent resistance to abrasion and recent studies have demonstrated that the inclusion of a lightweight aramid surfacing veil imparts this wear resistance to the composite, protecting the underlying lay-up and acting as both a durable and sacrificial layer. Without the inclusion of the aramid surface veil the findings indicate that the composite is damaged much more easily. Our aramid materials are incorporated at the surface of the composite, they demonstrate excellent resin uptake and are compatible with most common composite resin systems and fabrication techniques.

Improving Composite Lifetime

The micrograph on the right shows a wear test carried out using a pin-on-desk tribometer on a composite part containing an aramid surface veil. Very little damage has occurred to the composite as a whole and no damage has occurred to the underlying structural element (in this case a woven carbon). The 26 g/m² aramid veil on the surface acts as a sacrificial layer, remaining largely intact and protecting the rest of the composite structure from wear.
