Abstract
A laminate is proposed that includes a plurality of layers of nonwoven material consisting of fibers or filaments. The layers are at least partially bonded to each other. The layers include at least one unidirectional layer consisting of one or more parallel bundle(s) of unidirectionally oriented and interconnected fibers or filaments, and at least one additional layer consisting essentially of a random-laid nonwoven material.
Claims20
A laminate, comprising a plurality of layers of nonwoven material consisting of fibers or filaments, wherein these layers are at least partially bonded to each other, the plurality of layers comprising:
- at least one unidirectional layer consisting of one or more parallel bundle(s) of unidirectionally oriented and interconnected fibers or filaments;
- and
- at least one layer consisting essentially of a random-laid nonwoven material,
- wherein all layers forming the laminate consist of fibers or filaments that have bicomponent structures in the form of a core-sheath structure.
A method for making a laminate comprising a plurality of layers of nonwoven material consisting of fibers or filaments wherein the layers are at least partially bonded to each other, the method comprising:
- preparing for bonding at least one unidirectional layer consisting of one or more parallel bundle(s) of unidirectionally oriented and interconnected fibers or filaments;
- and
- preparing for bonding at least one layer consisting essentially of a random-laid nonwoven material,
- wherein all layers forming the laminate consist of fibers or filaments that have bicomponent structures in the form of a core-sheath structure.
