Liquid crystalline polymers LCPs high modulus fibers

High modulus fibers and films are produced from extended chain crystals in both conventional polymers, notably PE, and in liquid crystalline polymers (LCPs). The topic of high modulus organic fibers has been described and reviewed [15-17, 25] providing information on their preparation, structure, and properties. High modulus fibers are found in applications such as fiber reinforced composites for aerospace, military, and sporting applications. Industrial uses are for belts, ropes, and tire cords. Extended chain crystals can also form when polymers are crystallized very slowly near the melting temperature, but they are weak and brittle.
