ABSTRACT
Other authors have studied similar effects in LCPs, including the influence of the mold design on the tensile properties (II). It was found that the properties are strongly dependent on the flow field during injection of the melt in the mold, reflected in the specimen thickness and gate geometry. Thus, an increase in the specimen thickness gave rise to a decrease in tensile modulus and strength. The same effect was found as the injection rate increased. In both cases, different gate geometries produced some different parameter-property relationships. The variation of the tensile strength over the cross section of the specimens was also estimated. All these results were attributed in turn to the different orientation levels achieved in the liquid crystalline samples at different processing conditions and layers of the specimens.
