composite antiballistic This takeover represents an important strategic step in the "buy-and-build" process, around the five strategic core areas: protective fabrics, aerospace composites, antiballistic composite materials, artificial grass and geosynthetics.

1. Antiballistic shaped part comprising a stack of composite layers which are not linked to one another, each composite layer comprising two or more monolayers of unidirectionally oriented fibres in a matrix, the fibres in each monolayer being at an angle to the fibres in an adjoining monolayer, characterized in that the fibres are aramid fibres or poly(p-phenylenebenzobisoxazole) fibres, the composite layer contains at most 10% by weight of an elastomeric matrix material (calculated on the basis of the total weight of the composite layer), the composite layer has a total weight of at most 800 g/m2, and the fibre content in each monolayer is between 10 and 200 g/m2.

2. Antiballistic shaped part according to Claim 1, characterized in that the composite layer contains at most 7% by weight of the elastomeric matrix material.

3. Antiballistic shaped part according to Claim 1, characterized in that the composite layer contains at most 5% by weight of the elastomeric matrix material.

4. Antiballistic shaped part according to any one of Claims 1-3, characterized in that the matrix in addition to the elastomeric matrix material also contains a filler in an amount of from 5 to 80% by volume, calculated on the basis of the total volume of the elastomeric matrix material and the filler.

8. Antiballistic shaped part according to any one of Claims 1-7, characterized in that disposed on one or both sides of each composite layer there is a separating layer.

9. Body armour comprising an antiballistic shaped part according to any one of Claims 1-8, wherein the composite layer has a total weight of at most 500 g/m2, and the fibre content in each monolayer is between 10 and 150 g/m2.

10. Body armour according to Claim 9, wherein the composite layer has a total weight of at most 300 g/m2, and the fibre content in each monolayer is between 10 and 100 g/m2.

11. Method for fabricating an antiballistic shaped part according to any one of Claims 1-8, wherein the monolayer is produced by aramid yarns having a count of yarn between 800 and 2500 denier being wetted with a dispersion of the elastomeric matrix material and the filler which may be present.
