  • Stretch-staging of resin-based fiber-impregnated tape
    Patent number: 4348347
    Abstract: A stretch-staging method is disclosed for straightening continuous fiber columns impregnated within a resin-based tape material to increase the strength and reliability of the material. The tape material is supported about the circumference of a half-cylindrical fixture and separated therefrom by a thin lubricating film to reduce surface friction. Loads of substantially equal weight are longitudinally applied at opposite ends of the tape material about the fixture, and the combination is heated in an oven to an elevated temperature for a predetermined period of time thereby stretching and staging the tape material so that distorted fiber columns are straightened and retained in a straightened condition as the resin is advanced.
