Adhesive strip having a temporary fixing adhesive

1. A method for producing a composite from fibrous structures and an adhesive strip containing a final fixing adhesive, comprising the steps of

selecting an adhesive strip comprising a temporary fixing adhesive for a first temporary fixing of two substrates to one another as a first stage to a second final fixing of the two substrates, wherein the second final fixing is effected by a final fixing adhesive and this final fixing adhesive absorbs the temporary fixing adhesive in the course of the second final fixing, wherein the temporary fixing adhesive is a non-crosslinked pressure-sensitive adhesive and wherein it is dissolved in the final fixing adhesive in the course of the second final fixing;

temporarily fixing the fibrous structures in a mold and to one another using the adhesive strip;

adding the final fixing adhesive while dissolving the temporary fixing adhesive in the final fixing adhesive; and

curing the final fixing adhesive.

2. The method according to claim 1 , wherein adding the final fixing adhesive is effected by a resin infusion process.

3. The method according to claim 1 , wherein the temporary fixing adhesive comprises:

at least one polymer

optionally a tackifying resin

at least one reactive resin, wherein the temporary fixing adhesive comprises 100 parts of polymer and tackifying resin and at least 104 parts of the at least one reactive resin.

4. The method according to claim 3 , wherein the at least one polymer is present in the temporary fixing adhesive as a continuous polymer phase.

5. The method according to claim 3 , wherein at least one epoxy resin is present in the temporary fixing adhesive as the reactive resin.

6. The method according to claim 5 , wherein the final fixing adhesive is synthesized on the basis of at least one epoxy resin and the temporary fixing adhesive comprises the same grade of reactive resin as the reactive resin of the final fixing adhesive.

7. The method according to claim 5 , wherein at least one epoxy resin based on bisphenol A, bisphenol S, bisphenol F, an epoxy novolac, an epoxy cresol novolac, or an epoxidized nitrile rubber is present as the reactive resin.

8. The method according to claim 3 , wherein the at least one polymer is an elastomer or a thermoplastic.

9. The method according to claim 3 , wherein the at least one reactive resin is present dissolved at least partly, homogeneously in the continuous polymer phase.

10. The method according to claim 3 , wherein at least one polymer is selected from the group consisting of polyurethanes, nitrile-butadiene rubbers, polyamides, poly(ether ether ketone) (PEEK), poly(sulfone) (PSU), and poly(ether sulfone) (PES).

11. The method according to claim 1 , wherein the adhesive strip is present without a carrier as a transfer adhesive strip.
