    Abstract: A METHOD OF MAKING A VOID FREE RESIN IMPREGNATED GLASS REINFORCED FILAMENT WOUND ARTICLE. WHEN PRODUCED WITHOUT COLORING AGENTS, THE ARTICLE IS TRANSPARENT. DEAERATION IS ACHIEVED BY PRECURING THE ARTICLE AFTER FILAMENT WINDING. THAT IS, THE ARTICLE IS HEATED TO A TEMPERATURE LESS THAN THE TEMPERATUE AT WHICH HARDENING TO BE BSTAGE WILL OCCUR. THIS PRECURING TEMPERATURE IS MAINTAINED FOR AT LEAST ABOUT 24 HOURS BEFORE THE TEMPERATURE IS RAISED AND THE CURING PROCESS IS INITIATED. THE PROPERTIES OF THE MATERIALS USED IN THE RESIN MIX AND THE TEMPERATURES AND TIME INTERVALES AT WHICH THE STEPS OF THIS INVENTION ARE CARRIED OUT ARE DETERMINATIVE OF THE DEGREE OF SUCESS ACHIEVED.

    Abstract: An improved method of producing a filament wound article utilizing a mandrel of unique construction. This invention is useful is producing filament wound articles on mandrels having opposite winding surfaces having components normal to the axis of the mandrel. Such articles include pressure vessels, pipe having threads wound in at both ends, pipe having overhanging collars at both ends, or pipe threaded at one end with an overhanging collar at the other end.
