Aramid fibres are used as reinforcements in high performance composites, e.g. in aerospace applications, but they are also used extensively as reinforcements for rubber, tyres, plastics and concrete. Aramid fibres offer good mechanical properties at low density with the added advantage of toughness or damage/impact resistance. Weight reduction is a key requirement for cost and energy savings, while not impacting on design or performance. Employing aramid fibres as reinforcements has been limited by poor fibre-matrix interfacial adhesion because of the difficulties associated with the aramid fibre surface having insufficient reactive functional groups for covalent bonding with the matrix resin.
