  • Method and device for producing contoured composite laminate stiffeners with reduced wrinkling
    Patent number: 10399283
    Abstract: A contoured composite laminate stiffener is fabricated by assembling a substantially flat composite laminate charge and forming the charge into a substantially straight stiffener having a desired cross sectional shape. A contour is formed in the stiffener which has an inside radius and an outside radius. Ply wrinkling is substantially eliminated by reducing compression strain on the inside radius as the stiffener as being contoured.
