Method for producing a card body
A method is for manufacturing a stiff, multilayered card body for a portable data carrier, has steps including: making available a layer of an opaque plastic, making available a carbon fiber layer of carbon fiber fabric, impregnating the carbon fiber layer with epoxy resin, fusing the layers to form a half-product, printing the upper side of the carbon fiber layer of the half-product with a graphic pattern in a screen printing process or an offset printing process, laminating a plastic layer onto the printed upper side, and detaching the card body from the half product by means of a separating tool guided relative to the half-product along a path describing the edge contour of the card body.
1. A method for manufacturing a stiff, multilayered card body for a portable data carrier comprising the steps of:
making available a layer of an opaque plastic;
making available a carbon fiber layer of carbon fiber fabric;
impregnating the carbon fiber layer with epoxy resin;
fusing the layers to form a half-product;
printing the upper side of the carbon fiber layer of the half-product with a graphic pattern in a screen printing process or an offset printing process; and
detaching the card body from the half product by means of a separating tool guided relative to the half-product along a path describing the edge contour of the card body.
2. The method according to claim 1 , wherein a plastic layer is laminated onto the printed upper side.
3. The method according to claim 2 , wherein the plastic layer is transparent.
4. The method according to claim 1 , wherein two carbon fiber layers are made available and the plastic layer is arranged between the carbon fiber layers upon lamination.
5. The method according to claim 4 , wherein a graphic pattern is applied and a plastic layer is laminated on the back side of the carbon fiber layers of the half-product.
6. The method according to claim 1 , wherein the temperature upon fusion amounts to 20 to 60° C.
7. The method according to claim 1 , wherein the detachment takes place by means of a milling tool.
8. The method according to claim 1 , wherein the card body is hot stamped.
9. The method according to claim 1 , wherein the card body is personalized by a thermal transfer procedure or an engraving procedure.
10. The method according to claim 1 , wherein the plastic is PVC.
11. The method according to claim 1 , wherein the carbon fiber layers together have a thickness of 50% to 75% of the total thickness of the layers fused to a half-product.
