Abrasion Resistance
Composite wear is a significant problem. Using our aramid nonwovens as a surfacing veil provides a solution to this problem by drastically improving the abrasion resistance properties of your composites.
Product Data
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.

Results
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.

Typical Applications
Friction substrate
Providing an excellent substrate for friction products; TFP’s nonwovens have been used as an effective coating base for automotive clutch, brake and transmission system parts
Propellor blades
Our aramid nonwovens can be used on the leading edge of blades to improve wear resistance and longevity.
Canoe paddles, skis, hockey sticks and more...
Creating a more wear resistant surface finish, an important consideration in the manufacture of composite sporting goods, where it can increase the product resilience and life span.
Roll Covers
Our glass and aramid nonwovens are used in the manufacture of composite roll covers for high speed industrial rolls used in printing, textiles and papermaking to improve wear resistance. As well as improving the surface finish, the aramid can also be blended with conductive fibres to provide protection from surface static discharge.
