Fiber component having fiber rods connected to form a framework
View Patent ↗A fiber component has at least three fiber rods which each have fibers extending continuously in the axial direction of the fiber rods, wherein at least two of the three fiber rods each form a support rod and at least one of the three fiber rods forms a connecting rod. The support rods are arranged substantially parallel in the axial direction thereof and spaced from each other. The connecting rod connects the support rods to each other. The connecting rod forms a node point with the support rod in question at each of the connecting points between the connecting rod and the support rods.
1. A method of producing a framework structure, comprising:
producing a nonpermanent mold of wax by a 3D printing method;
placing at least three fiber rods, each having fibers extending continuously in an axial direction of the fiber rods, in the nonpermanent mold of wax such that:
the at least three fiber rods form a framework structure as arranged with respect to one another,
at least two of the three fiber rods, each forming a support rod, are arranged parallel to one another and spaced apart from one another, and
at least one of the three fiber rods, forming a connecting rod, is wound around the two support rods in a zigzag-shaped profile and forms node points therewith, wherein the connecting rod changes an orientation of its axial direction only at the node points and extends between the node points without changing the orientation of its axial direction; and
impregnating the at least three fiber rods with a matrix in the nonpermanent mold of wax;
connecting the two support rods with the connecting rod at the node points by the matrix in the nonpermanent mold of wax;
enclosing an entirety of the framework structure by the matrix and filling cavities in the framework structure by the matrix in the nonpermanent mold of wax; and
after a curing time, melting the nonpermanent mold of wax such that the melted nonpermanent mold flows out of the framework structure formed by the at least three fiber rods.
2. The method according to claim 1 , wherein
the at least three fiber rods are placed in the nonpermanent mold of wax and arranged with respect to one another by a robot.
