Method of manufacturing a molded article having good dimensional stability

摘要

A laminated sheet comprises a first layer of a melt-phase anisotropy exhibiting thermoplastic polymer, having a negative linear expansion coefficient in the direction of the polymer flow and a second layer having a positive linear expansion coefficient in the direction of the polymer flow, both layers having been laminated one on another in the alternative way, further each layer having a thickness such that the negative linear expansion coefficient of said first layer and the positive linear expansion coefficient of the second layer having been offset against each other.
