Abstract
A dental material comprising a symmetrically rod-shaped fiber-reinforced composite comprising at least two layers of preimpregnated fibers, wherein the preimpregnated fibers comprise fibers coated with a resin, wherein the layers are unbraided, and wherein each layer is unidirectionally disposed on the preceding layer in a direction that is different from the direction of the preceding layer. The rod-shaped composite may be hollow and contain a channel throughout the axial length of the rod or may contain a shaft or other material that is inserted into the channel.
Claims32
A material for dental or medical use comprising:
- a symmetrically rod-shaped fiber-reinforced composite comprising a metal shaft and at least two layers of impregnated fibers wound directly on the metal shaft to be in direct adhering contact with the metal surface of the metal shaft, wherein the impregnated fibers comprise fibers coated with a resin;
- wherein the layers are unbraided;
- and wherein each layer is unidirectionally disposed on the preceding layer in a direction that is different from the direction of the preceding layer.
A material for dental or medical use comprising:
- a symmetrically rod-shaped fiber-reinforced composite comprising a hollow metal shaft and a plurality of layers of resin-coated glass fibers wound directly on the hollow metal shaft to be in direct adhering contact with the metal surface of the metal shaft, and an exterior surface of the hollow metal shaft is abraded to increase adhesion to the plurality of layers, wherein the plurality of layers are unbraided;
- and wherein each of the plurality of layers is unidirectionally disposed on the preceding layer in a direction that is different from the direction of the preceding layer.
