Title:
管状の高分子材料の強度を高める方法
Document Type and Number:
Japanese Patent JP3124707
Kind Code:
B2
Abstract:
A method of manufacturing polymeric material having enhanced structural integrity includes heating the material to a temperature between the material's glass transition temperature and the material's melt temperature. Once heated, the material is highly overstretched in a first direction and moderately overstretched in a second direction. The material is then held in the overstretched condition while it is allowed to cool to room temperature. Cooling is followed by reheating to a curing temperature. After curing for a predetermined period, the material is again allowed to cool. The completed material has high polymeric orientation in the first direction and moderate polymeric orientation in the second direction. Therefore, the material is characterized by enhanced structural integrity and absence of pinhole defects common to highly oriented polymeric materials.
