  • Method of manufacturing curved composite structural elements
    Patent number: 7943076
    Abstract: A curved composite element is laid up over a tool having first and second curved tool surfaces possessing differing radii of curvatures. A plurality of composite fiber ply segments are arranged in substantially side-by-side relationship into a group. The ply segments are formed as a group onto the first curved tool surface, and the group is then formed from the first curved tool surface onto the second curved tool surface.

  • Method and tools for fabricating composite beams
    Patent number: 7754045
    Abstract: Three simple tools are used to both preform and mold a composite layup into a J-beam. A first composite charge is preformed into a C-channel using a first tool, and a second composite charge is formed into a Z-channel using both the first tool and a second tool. The C-channel and Z-channel are laid up between the first and second tools, following which a perform composite cap and third tool are added to complete the layup and the tool assembly. The layup may be molded using vacuum bagging techniques and subsequently cured while held in the tool assembly.

  • Method for forming a composite support beam
    Patent number: 7588711
    Abstract: A method of forming a support beam is provided. One exemplary method of forming a support beam includes supporting a C-shaped charge upon a first forming tool and placing an additional composite charge upon at least a portion of the C-shaped charge and a second forming tool proximate the first forming tool. The method of forming a support beam further includes positioning a fixed forming tool proximate a first portion of the additional charge and bending the additional charge about the forming tool.
