Abstract
The object of the invention is a process for production of a reinforcement (10) for composite material comprising at least two layers (12, 14) intended to be embedded in a polymer matrix, characterized in that at least one (14) of the layers is comprised of continuous filaments (16) in one main direction F and in that these filaments are positioned with variable spacing along this main direction F.

Process for production of snow board modules comprising a continuous process producing plural reinforcement (10) of composite material comprising at least two layers (12, 14) embedded in a polymer matrix,
- wherein at least one (14) of the layers is comprised of continuous filaments (16) in one main direction (F),
- wherein said continuous filaments are positioned with variable spacing along the main direction (F),
- wherein the number of filaments, as measured in a cross section to the one main direction, is constant along the entire one main direction,
- wherein the filament density of the of the composite is lower in ends zones and higher in a center zone along the one main, and
- wherein each produced module is a snow board module.
A process for production of a reinforcement (10) for composite material comprising at least two layers (12, 14) embedded in a polymer matrix, comprising the steps of:
- a continuous process embedding continuous filaments (16) in a polymer resin and obtaining cross-linking;
- and
- from the continuous process, providing plural snow board modules (18), each snow board module (18) comprised of plural layers (12, 14) with the continuous filaments (16) running in a longitudinal direction (F), the filaments positioned with variable spacing along the longitudinal direction (F),
- wherein the number of filaments, as measured in a cross section to the one main direction, is constant along the entire one main direction, and
- wherein the filament density of the of the composite is lower in ends zones and higher in a center zone along the one main direction.
