Abstract

The present disclosure provides a tape comprising: a) a single layer comprising a crosslinked polymer, selected from the group consisting of crosslinked polyurethane, crosslinked polyurea, and crosslinked mixed polyurethane/polyurea polymer, and b) an adhesive layer. In another embodiment, the tape comprises at least one layer comprising a semi-interpenetrating polymer network of a crosslinked acrylate and an uncrosslinked polymer selected from the group consisting of polyurethane, polyurea, and mixed polyurethane/polyurea polymer.

Claims (38)

1 . An erosion resistant construction comprising:

a) an element of an aircraft comprising:

i) an aircraft skin segment having an external surface, and

ii) a deicing mechanism associated with said aircraft skin segment capable of heating said external surface to temperatures in excess of 65° C.;

b) a tape comprising:

i) at least one layer comprising a crosslinked polymer, selected from the group consisting of crosslinked polyurethane, crosslinked polyurea, and crosslinked mixed polyurethane/polyurea polymer, and

ii) an adhesive layer;

wherein the tape is bonded to the external surface of the aircraft skin segment by the adhesive layer.

2 . The construction according to claim 1 wherein the tape comprises no polymer layer other than the adhesive layer that does not contain crosslinked polymer.

3 . The construction according to claim 1 wherein the tape comprises no uncrosslinked polymer other than the adhesive layer.

4 . The construction according to claim 1 wherein the crosslinked polymer incorporates at least one acrylate component.

5 . The construction according to claim 1 wherein the crosslinked polymer is blended with at least one acrylate component.

6 . The construction according to claim 1 wherein the crosslinked polymer is a crosslinked polyurethane.

7 . The construction according to claim 1 wherein the crosslinked polymer is a crosslinked polyurea.

8 . The construction according to claim 1 wherein said at least one layer comprising a crosslinked polymer is a single layer consisting essentially of crosslinked polyurethane.

9 . The construction according to claim 1 wherein said at least one layer comprising a crosslinked polymer is a single layer consisting essentially of crosslinked polyurethane which incorporates at least one acrylate component.

10 . The construction according to claim 1 wherein said at least one layer comprising a crosslinked polymer is a single layer consisting essentially of crosslinked polyurea.

11 . The construction according to claim 1 wherein said at least one layer comprising a crosslinked polymer is a single layer consisting essentially of crosslinked polyurea which incorporates at least one acrylate component.

12 . The construction according to claim 1 wherein the external surface of the aircraft skin segment includes one or more layers of paint and/or primer.

13 . A tape comprising:

a) a single layer comprising a crosslinked polymer, selected from the group consisting of crosslinked polyurethane, crosslinked polyurea, and crosslinked mixed polyurethane/polyurea polymer, and

b) an adhesive layer.

14 . The tape according to claim 13 wherein said single layer comprises no uncrosslinked polymer other than the adhesive layer.

15 . The tape according to claim 13 wherein the crosslinked polymer incorporates at least one acrylate component.

16 . The tape according to claim 13 wherein the crosslinked polymer is blended with at least one acrylate component.

17 . The tape according to claim 13 wherein the crosslinked polymer is a crosslinked polyurethane.

18 . The tape according to claim 13 wherein the crosslinked polymer is a crosslinked polyurea.

19 . An erosion resistant construction comprising:

a) an element of an aircraft comprising:

i) an aircraft skin segment having an external surface, and

ii) a deicing mechanism associated with said aircraft skin segment capable of heating said external surface to temperatures in excess of 65° C.;

b) a tape comprising:

i) at least one layer comprising a crosslinked elastomeric polymer, and

ii) an adhesive layer;

wherein the tape is bonded to the external surface of the aircraft skin segment by the adhesive layer.

20 . The construction according to claim 19 wherein the tape comprises no polymer layer other than the adhesive layer that does not contain crosslinked polymer.

21 . The construction according to claim 19 wherein the tape comprises no uncrosslinked polymer other than the adhesive layer.

22 . The construction according to claim 19 wherein the external surface of the aircraft skin segment includes one or more layers of paint and/or primer.
