摘要：

The mechanical properties and structure of a thermotropic liquid crystalline copolyester have been investigated. Shear and tensile moduli of oriented samples were determined over the temperature range -100 degrees C to 190 degrees C. Crystal size and crystal moduli measurements were also undertaken. An analysis of the anisotropic mechanical behaviour is undertaken using a simplified aggregate model. (C) 1997 Elsevier Science Ltd.
