  • Patent number: 6561459
    Abstract: A wing of composite material has an upper skin, a lower skin and a plurality of intermediate spars arranged between the upper and the lower skin. The intermediate spars extend from roots to tips of the upper and the lower skins. The intermediate spars are integrally formed with the upper and the lower skins or are adhesively bonded to the upper and the lower skins. The wing has a small number of parts, needs greatly reduced time for fabrication and can be fabricated at a low cost.

  • Publication number: 20030062653
    Abstract: This invention is a method of fabricating a panel of composite material. The panel includes two outside skins and stringers attached inside of the two outside skins for reinforcing the two outside skins. A plurality of stringers for reinforcing outside skins is formed from dry preformed fibers. The plurality of stringers are disposed at a predetermined interval. Adjacent two stringers is connected with each other via a connecting member made from dry preformed fibers. The connected stringers and the connecting members are set into a forming mold. Resin is introduced into the forming mold to impregnate the dry preformed fibers of the stringers and the connecting members. The resin-impregnated stringers and the resin-impregnated connecting members are cured to unite the resin-impregnated stringers and the resin-impregnated connecting member into one body of “Rudder Shape” stringer. A prepreg is laminated onto an outside-skin shaping mold.
