The conditions under which the LCP reinforced thermoplastic composites can be thermoformed have been investigated. Two liquid crystalline polymers a copolyester of terephthalic acid, phenyl hydroquinone, and phenyl ethyl hydroquinon and a copolyester of p-hydroxy benzoic acid and 6-hydroxy- 2naphthoic acid were used. An amorphous polyetherimide and a semi-crystalline polypropylene have been used as the matrix materials for making the composites. The thermoformability has been studied as a function of the sheet preheating temperature, and the mold temperature for various compositions of composites. Morphology and molecular orientation of the thermoformed parts before and after thermoforming have also been studied.
