A binder is applied to particles which are then combined with fibers to bind the particles to the fibers. The particles have functional sites for forming a hydrogen bond or a coordinate covalent bond. The fibers have hydrogen bonding functional sites. The binder comprises binder molecules, the binder molecules having at least one functional group that is capable of forming a hydrogen bond or a coordinate covalent bond with the particles, and at least one functional group that is capable of forming a hydrogen bond with the fibers. A substantial portion of the particles that are adhered to the fibers may be adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder in turn may be adhered to the fibers by hydrogen bonds. Fibers containing particles bound by this method are easily densified.

A method according to claim 1, wherein, at least initially, material of the material layer within said partial layer volume is present in the superheated matter substantially unchanged. 3. A method according to claim 1, wherein the superheated matter from material of the material layer within said partial layer volume expands substantially stoichiometrically during detachment of the segment. 4. A method according to claim 1, wherein detachment of said cohesive, solid partial layer is performed with a single laser pulse. 5. A method according to claim 1, wherein the cohesive, solid partial layer is accelerated away from the carrier by hydrodynamic expansion of the superheated matter in the partial layer volume. 6. A method according to claim 5, wherein the cohesive, solid partial layer is accelerated in the direction of a substrate. 7. A method according to claim 6, wherein the cohesive, solid partial layer is fixed on the substrate. 8.

A method according to claim 8, wherein the substrate is positioned at a defined distance from the carrier at which fixing of the cohesive, solid partial layer on the substrate occurs due to impact. 10. A method according to claim 8, wherein the size of the beam cross-section is selected so that the impact energy leads to said fixing of said cohesive, solid partial layer on the substrate. 11. A method according to claim 8, wherein the energy of the laser pulse is selected so that the impact energy leads to said fixing of said cohesive, solid partial layer on the substrate. 12. A method according to claim 8, wherein the pulse duration of the laser pulse is selected so that the impact energy leads to said fixing of said cohesive, solid partial layer on the substrate. 13. A method according to claim 1, wherein the detached cohesive, solid partial layer after being detached from said material layer is removed by a remover. 14. A method according to claim 1, wherein the pulse duration of the laser pulse is determined in such a way that the partial layer volume extends transversely to the plane of the layer over a thermal penetration depth of electrons heated during the pulse duration of the laser pulse. 15. A method according to claim 1, wherein the pulse duration of the laser pulse is smaller than the material-dependent thermal relaxation time of electrons of the material. 16. A method according to claim 1, wherein the pulse duration of the laser pulse is shorter than 50 picoseconds. 17. A method according to claim 15, wherein the material layer is selected so that the laser pulse couples to free electrons of the material of the material layer. 18. A method according to claim 15, wherein the material layer is selected so that the laser pulse itself produces the electrons necessary for coupling by means of multiple photon absorption in the material layer. 19. A method according to claim 15, wherein the material layer is selected so that the laser puls
