Component arrangement
View Patent ↗An arrangement which has a first component and a second component fastened to each other in a clamping manner. At least the first or second component is a fiber/plastic composite component. The arrangement has a securing element which generates a pressing force that presses the components against each other such that the components are secured to each other in a clamped manner. A friction-coefficient-increasing element is arranged between the first and second components in a pressing region in which the first and second components are pressed against each other by the pressing force. The friction-coefficient-increasing element increases a static friction produced for the pressing force in contrast to a case in which such an element is not arranged in the pressing region. The invention also provides a method for fastening the first component to the second component.
1. An arrangement, comprising:
a first component and a second component, wherein at least the first or second component is a fiber plastic composite component;
a fastener which generates a pressing force pressing the components against each other in such a manner that the components are fastened to each other in a clamping manner; and
a threaded holder, wherein
the fastener is a screw that has a head disposed on a side of the first and second components and a portion that passes through respective passages in the first and second components and wherein an end of the portion is received within the threaded holder,
an adhesive is disposed between the end of the portion of the screw and the threaded holder,
a friction-coefficient-increasing element is arranged between the first and second components in a pressing region in which the first component and the second component are pressed against each other by the pressing force,
the friction-coefficient-increasing element increases a static friction arising for the pressing force in comparison to a case in which the friction-coefficient-increasing element is not arranged in the pressing region, and
wherein the friction-coefficient-increasing element is a roughened disk or a sheet of material with a roughened surface and wherein particles are secured on the roughened disk or the roughened surface of the sheet of material.
2. The arrangement according to claim 1 , wherein the particles are silicon carbide particles and/or quartz particles and/or corundum (Al2O3) particles and/or emery particles and/or pumice stone particles and/or garnet particles and/or diamond particles.
3. The arrangement according to claim 1 , wherein the fiber plastic composite component has an anti-corrosion layer on a surface facing the other component and/or on a surface facing away from the other component.
4. The arrangement according to claim 3 , wherein the anti-corrosion layer is a glass fiber layer.
5. The arrangement according to claim 4 , wherein
the first and second components are fiber plastic composite components, and
the first and second components have an anti-corrosion layer on the surface facing the other component and on the surface facing away from the other component.
6. The arrangement according to claim 5 , wherein the anti-corrosion layer is a glass fiber layer.
7. The arrangement according to claim 6 , wherein the fastener is formed from a metal and lies against the anti-corrosion layer on the fiber plastic composite component.
8. The arrangement according to claim 3 , wherein the fastener is formed from a metal and lies against the anti-corrosion layer on the fiber plastic composite component.
9. A method for fastening a first component to a second component, wherein at least the first or second component is a fiber plastic composite component, the method comprising the steps of:
applying a friction-coefficient-increasing element to the fiber plastic composite component or to the other component; and
fastening the components in a clamping manner by a screw and a threaded holder, wherein a head of the screw is disposed on a side of the first and second components and a portion of the screw passes through respective passages in the first and second components, wherein an end of the portion is received within the threaded holder and an adhesive is disposed between the end of the portion and the threaded holder, such that the friction-coefficient-increasing element is arranged between the components in a pressing region in which the components are pressed against each other, wherein
the friction-coefficient-increasing element acts in such a manner that a static friction arising for the components connected in the clamping manner is increased in comparison to a case in which the friction-coefficient-increasing element is not arranged in the pressing region, and
wherein the friction-coefficient-increasing element is a roughened disk or a sheet of material with a roughened surface and wherein particles are secured on the roughened disk or the roughened surface of the sheet of material.
