Fibres
Aramid fibre
Golden aromatic polyamide fibre, typically PPTA, with very low density, excellent toughness, fatigue resistance and energy absorption.
In simple terms
Golden aromatic polyamide fibre, typically PPTA, with very low density, excellent toughness, fatigue resistance and energy absorption.
Best for
Impact, abrasion, tension members and lightweight ballistic protection.
Watch out for
Weak transverse/compressive behaviour, difficult machining, moisture sensitivity and demanding fibre/matrix adhesion.
Typical applications
Ballistic panels, protective equipment, ropes, tyres, radomes and impact-resistant laminates.
