Patent ID: 8062453

Claim:
A method of winding fibers on a mandrel, the wound fibers being in tension, comprising: providing a source of fibers, imposing a torque on the source that resists dispensing the fibers from the source to exert a tension on the fibers; adding ultra-violet sensitive material that is polymerized by exposure to ultra-violet light to a resin matrix; impregnating dispensed fibers with the additive containing resin matrix, rotating a mandrel to wind the impregnated fibers on the mandrel, the rotation of the mandrel acting to overcome the torque on the source and putting the fibers in tension; and in situ, quasi instantaneously polymerizing the additive containing resin matrix on the mandrel by exposing the additive containing resin matrix to ultra-violet light for a selected period of time, such polymerization acting to lock in the tension in the fibers at the time of polymerization.
