Composite synthetic-resin sheet material
Abstract
Abstract A METHOD OF MAKING A SHEET MATERIAL WHICH COMPRISES SANDWICHING A MOLECULARLY UNORIENTED SYNTHETIC-RESIN SHEET HAVING A RELATIVELY LOW MOLECULAR-DISORIENTATION TEMPERATURE BETWEEN A PAIR OF UNAXIALLY ORIENTED SYNTHETIC-RESIN SHEETS HAVING RELATIVELY HIGH MOLECULAR-DISORIENTATION TEMPERATURES, ARRANGING THE ORIENTATION DIRECTION OF ONE OF THE UNAXIALLY-ORIENTED SHEETS TO LIE AT AN ANGLE (GENERALLY TRANSVERSELY) TO THE ORIENTATION DIRECTION OF THE OTHER UNIAXIALLY-ORIENTED SHEET, AND HEATING THE LAMINATED ASSEMBLY TO A TEMPERATURE SUFFICIENT TO FUSE THE NONORIENTED SHEET TO THE MOLECULARLY ORIENTED SHEETS, BUT BELOW THE MOLECULARDISORIANTATION TEMPERATURE OF THE ORIENTED SHEETS.
