Panel of composite material and method of fabricating the same

摘要

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. The united stringers and connecting members are disposed onto the laminated prepreg. The laminated prepreg and the united stringers and connecting members are cured to form an outside-skin part in which the stringers, the connecting members and an outside skin are united. Two outside-skin parts are connected via a reinforcing member to form a box of composite material.
