Abstract

Laminate containing a first layer and a second layer attached to the first layer, said second layer comprising high tenacity yarns, characterized in that the first layer is made out of a material selected out of the group consisting of a metal, a plywood, a solid thermoplastic or thermosetting polymer, and a composite material containing carbon fibers and/or glass fibers, and the high tenacity yarns have a tenacity of at least 0.5 GPa and are positioned in a grid structure. The laminate is damage resistance and is suitably used for the manufacture of air freight containers.

Claims (14)

1. A laminate comprising:

a first layer; and

a second layer attached to the first layer, wherein

the second layer comprises between 300 and 2000 grams of high tenacity yarns per square meter, and wherein

the first layer is made out of a material selected out of the group consisting of a metal, a plywood, a thermoplastic or thermosetting polymer, and a composite material containing carbon fibers and/or glass fibers, and wherein

the high tenacity yarn have a tenacity of at least 0.5 GPa and are positioned in a grid structure wherein in the grid structure the distance between centerlines of adjacent yarns in the grid is larger than a diameter of a yarn.

2. The laminate according to claim 1 , wherein the first layer has a bending modulus of at least 10 GPa.

3. The laminate according to claim 1 , wherein the high tenacity yarn contains aramid filaments, filaments of S-glass, filaments of high tenacity polyester.

4. The laminate according to claim 1 , wherein the high tenacity yarn contains filaments of ultra-high molecular weight polyethylene.

5. The laminate according to claim 1 , wherein the grid structure is formed by two or more arrays of parallel yarns, the angle between the yarns of the arrays being larger than 0°.

6. The laminate according to claim 1 , wherein the high tenacity yarn has a thickness of between 800 and 35000 dtex.

7. Construction for air transportation, the construction containing a laminate according to claim 1 .

8. An air freight container comprising the laminate according to claim 1 .

9. A cargo hole liner comprising the laminate according to claim 1 .
