HIGH-STRENGTH, HIGH-MODULUS FIBRES MADE FROM LINEAR POLYMERS: PRINCIPLES OF FABRICATION, STRUCTURE, PROPERTIES, AND USE

The current types of ultrastrong and high-modulus fibres made from linear fibre-forming polymers structure, principles of fabrication, properties, and basic areas of application - are examined. Most of the attention is focused on carbocyclic and heterocyclic para-aramid fibres, whose production capacities have reached 60,000 tons a year, the features of their structure and properties and areas of application. High-strength fibres made from other types of aromatic polymers (poly-p-phenylene benzobisoxazoles and thiazoles, polyarylates, polyvinyl alcohol, ultrahigh-molecular-weight polyethylene) are also briefly examined.
