  • Patent number: 6146481
    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.
