Abstract
A method for identifying a fiber-reinforced plastic component includes the acts of providing a fiber preform, applying a label to the fiber preform and holding it in place, inserting the preform together with the label in a mold and closing the mold, and infiltrating the preform with a plastic compound and curing it in the closed mold. In order to reliably identify the plastic component, the label comes to rest on a flow aid portion formed on the inner mold wall which has at least one channel-shaped depression. The longitudinal extension of the flow aid portion projects beyond the label.

A method for identifying a fiber-reinforced plastic component, comprising the acts of:
- providing a semifinished fiber product;
- applying a label to the semifinished fiber product;
- adhesively bonding the label to a surface of the semifinished fiber product;
- inserting the semifinished fiber product with the adhesively bonded label into a mold and closing the mold;
- and
- infiltrating the semifinished fiber product with a plastic compound and curing the plastic compound in the closed mold to form the fiber-reinforced plastic component;
- wherein a flow aid portion is formed on a portion of an inner wall of the mold with a lattice-shaped arrangement of channel-shaped depressions of which at least one channel-shaped depression has a length which projects beyond the label and wherein the label lies on the portion of the inner wall of the mold with the flow aid portion;
- wherein during the curing, a resin lattice is formed by the lattice-shaped arrangement which spans the label and which securely integrates the adhesively bonded label into the fiber-reinforced plastic component;
- wherein the lattice-shaped arrangement covers less than 30 percent of an area of the label or less than 20 percent of the area of the label.
A method for identifying a fiber-reinforced plastic component, comprising the acts of:
- providing a semifinished fiber product;
- applying and fixing a label to the semifinished fiber product;
- inserting the semifinished fiber product with label into a mold and closing the mold;
- and
- infiltrating the semifinished fiber product with a plastic compound and curing the plastic compound in the closed mold to form the fiber-reinforced plastic component;
- wherein the label lies on a flow aid portion which is formed on an inner wall of the mold with a lattice-shaped arrangement of channel-shaped depressions of which at least one channel-shaped depression has a length which projects beyond the label;
- wherein during the curing, a resin lattice is formed by the lattice-shaped arrangement which spans the label and which securely integrates the label into the fiber-reinforced plastic component;
- wherein the lattice-shaped arrangement covers less than 30 percent of an area of the label or less than 20 percent of the area of the label.
