Abstract
The areally extended composite material (1) contains fibers (20, 30) which are impregnated with plastic (21). The composite material comprises at least two arrays of parallel fiber cords (2, 3) which extend in different directions and which form a web, mesh or grid. The fiber cords can be bundle-like or band-like. The fibers (20) of a first array (2) are impregnated with substantially more plastic (21) than the fibers (30) of a second and possibly of a further array (3). The composite material (1) is stiff in the direction of the fibers of the first array and is flexible transversely to this direction. Openings advantageously exist between the fiber cords.
Claims11
An areally extended composite material including fibers and thermoplastic impregnations, the material comprising at least two arrays of parallel fiber cords that may be a bundle or band the two arrays extending in different directions, forming a web, mesh or grid, wherein the fibers of the first array are impregnated with more thermoplastic then the fibers of a second array such that the composite material is stiff in a direction of the fibers of the first array and is flexible transversely to said direction, and wherein openings exist between the fiber cords.
