Abstract

879,679. Laminates. HUNTING MHOGLAS Ltd. July 26, 1960 [May 1, 1959], No. 14920/57. Addition to 747,257. Class 140. [Also in Group XI] A flexible electric heating resistance is formed of a laminate of resistance elements formed according to the method of the parent Specification (see Group XI), in which a layer of colloidal graphite and a coating of a resin are applied to an inorganic fabric such as fibre glass, the sheet then being cured at 500‹ C. The laminate is manufactured by superimposing two or more of such sheets in the uncured state one above the other and applying a moderate pressure of 7 lb. per square inch before and/or during curing, at a temperature of 130-150‹ C. for 20 minutes. The pressure applied is insufficient to squeeze resin from the assembly but sufficient to expel air and bring threads of adjacent sheets into contact. The laminate may be singly or multiplely curved by using an appropriate mandrel, and if necessary, tailoring the fabric. The resin may be that known by the Registered Trade Mark " Araldite F."
