Abstract: A method of making a filament wound tube having smooth surfaces. Fiber glass filaments are passed through successive resin baths containing particles of a wear resistant additive. These resin baths are deaerated to reduce the existence of voids and pits in the resin in the finished tube. The filaments are flattened and are slowly helically wound in a first layer onto a mandrel. Subsequent layers are overwound about the first layer, the resin is cured, and the filament wound tube formed thereby is removed from the mandrel.

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 threaded filament wound pipe and the method of manufacture thereof. The improvement comprises helically winding resin impregnated fiberglass filaments upon a mandrel knurled at the ends in the form of helical threads. The helpical winding pitch is greater than the thread pitch. As a result, the fiberglass filaments alternately deviate in radial disposition with respect to the pipe axis, thereby forming both interior and exterior pipe threads at the ends of the finished pipe.

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.

Abstract: AN IMPROVED THREADED FILAMENT WOUND PIPE AND THE METHOD OF MANUFACTURE THEREOF. THE IMPROVEMENT COMPRISES HELICALLY WINDING RESIN IMPREGNATED FIBERGLASS FILAMENTS UPON A MANDREL KNURLED AT THE ENDS IN THE FORM OF HELICAL THREADS. THE HELICAL WINDING PITCH IS GREATER THAN THE THREAD PITCH. AS A RESULT, THE FIBERGLASS FILAMENTS ALTERNATELY DEVIATE IN RADIAL DISPOSITION WITH RESPECT TO THE PIPE AXIS, THEREBY FORMING BOTH INTERIOR AND EXTERIOR PIPE THREADS AT THE ENDS OF THE FINISHED PIPE.

Abstract: A wear-resistant tube and the method of manufacture thereof. A tube is produced having an interior gel coat layer containing a first thermosetting resin system within which particles of mica are dispersed. Fiberglass filaments coated within a second thermosetting resin system are overwound about this interior layer to form an exterior layer. The interior and exterior layers are bounded to each other and together form a wear-resistant tube.

Abstract: 1315038 Pipes AMALGA CORP 23 July 1970 [29 July 1969] 35672/70 Heading F2P A tube having a wear resistant inner surface comprises an inner layer of a thermosetting resin containing mica particles, and an outer layer of glass fibre filaments, coated by and bonded with a thermosetting resin, and overwound about and bonded to the inner layer. The tube is produced by coating a mandrel with the thermosetting resin containing the mica particles, overwinding the coated glass fibre filaments about the first layer, curing the resultant tube, and removing the tube from the mandrel. The mandrel is cleaned with a solvent, heated to at least 218 C. for at least four hours, cooled to room temperature, coated with a release agent, heated to at least 93 C., and coted with a gel coat comprising finely ground mica dispersed in a thermosetting resin, the coat being cured at room temperature for at least 45 minutes; glass fibre elements are then passed through a thermosetting resin system, overwound about the inner layer, cured at 100 C. minimum for four hours, the tube then being removed from the mandrel. The tube may be post cured at 149 C. for four hours then cooled slowly to room temperature for one hour. Either thermosetting resin system may be an epoxy resin or polyester resin with any conventional hardener. Pigments may be added for colouring the layers.

Abstract: 1312350 Making pipes by winding on mandrels AMALGA CORP 9 July 1970 [9 July 1969] 33295/70 Heading B8G [Also in Division F2] A mandrel having an unthreaded central portion 9 and at least one end 7 helically knurled as at 6 is coated with a release agent and then helically wound with resin-impregnated glass filaments at a winding pitch greater than the pitch of the helical knurls. The resin impregnated filaments are then cured and at least part of the mandrel is removed to leave the windings in the form of a pipe. As shown the mandrel comprises one end 7 that is helically knurled as at 6 and a smaller end 10 that is helically knurled as at 5, the diameters of the two ends being such that the finished pipes can be screwed one into another. The smaller end 10 may comprise an externally knurled ring 11 that is not coated with a release agent in order that it may remain within the pipe on a reinforcing member.
