    Abstract: In the present invention, a technique is described for manufacturing microtube devices which have peripheral geometries that are not uniform along the tube or device axis. These geometries may exist in only one location on the periphery of the microtube device or geometries may be repeated either uniformly or non-uniformly with micron or sub-micron precision along the tube or device axis. The preferred manufacturing process involves forming a complex mandrel, ie., (one, for example, that can not be formed by extrusion or pultrusion under constant processing conditions) and giving it at least one metallic and/or nonmetallic coating by any of a variety of techniques. The complex mandrel can then be removed by appropriate chemical or physical means that do not adversely affect the coating(s) desired for the wall. The result is a microtube structure having an axial profile duplicating that on the mandrel from which it was formed.

    Abstract: A fiber reinforced thermoplastic pipe member is obtained by a novel continuous process in which the reinforcement fibers are wrapped about the outer pipe surface in an unbonded condition while the pipe member continuously moves in a linear direction and which is followed by sufficient heating of the moving fiber wrapped pipe member to cause thermal bonding between the applied fibers and the pipe member. Automated apparatus for carrying out the continuous process is also disclosed.

    Abstract: A reinforced composite vessel and a method for its manufacture. A cylindrical mandrel capped by two convex, cylindrically symmetrical caps is supported externally only at a proximal end thereof, and is rotated and translated with respect to a strand delivery system to wrap the mandrel with at least two strands, in multiple strokes. A mechanism is provided to ensure that the strands are laid flat and undamaged onto the mandrel. As the caps pass the strand delivery system, the strands overlap and anchor each other. A liquid binder is mixed intimately with a catalyst and is depressurized to release dissolved gases. The binder is applied to the wrapped mandrel by causing a quantity of the binder sufficient to coat the mandrel to surround one end of the mandrel and then move towards the other end as an advancing annulus. This is accomplished by placing the mandrel vertically in a coating chamber along with the volume of binder, and reducing the volume of the chamber to force the binder up past the mandrel.
