Claims (10)

An integrated expanded metal mesh having a down roll direction, wherein the mesh is:
a) a plurality of linear strands substantially parallel to the down-roll direction;
b) a plurality of intersecting strands intersecting with said linear strands at a node;
The integrated expanded metal mesh, wherein the length measured in the down roll direction is greater than 3.00 m. Measured along the linear strands, the average distance between nodes is 4.000cm below and 0.030cm greater, integral expanded metal mesh according to claim 1. c) the integral expanded metal mesh of claim 1 or 2 ;
d) a polymer matrix. The composite material according to claim 3 , wherein the polymer matrix is an uncured curable resin or a partially cured curable resin. e) Woven fiber scrim or
f) Non-woven fiber scrim
The composite material according to claim 3 , further comprising one or both of the following. A method for producing an integrated expanded metal mesh according to claim 1 or 2 ,
g) preparing a metal sheet having a down-roll direction;
h) a step of simultaneously performing a cutting step near the leading end of the metal sheet and a bending step of the metal strands of the sheet using a tool arranged obliquely with respect to the down-roll direction of the metal sheet. Wherein said cutting step comprises cutting a row of spaced apart slits in said sheet, wherein said bending step comprises bending down a thin strand of metal of said sheet adjacent to each slit. So that the strands protrude in a direction perpendicular to the plane of the metal sheet,
i) advancing the metal sheet in the down-roll direction;
j) repeating the step h) so that the distance adjacent to the row of slits is a line substantially parallel to the down-roll direction of the metal sheet. The tool may include a plurality of protrusions extending in a direction orthogonal to the sheet, the protrusions having a triangular or arcuate shape, and the rows of slits being collinear rows of slits. Item 7. The method according to Item 6 . The method according to claim 6 or 7 , wherein, with each repetition of step h), the tool moves alternately between two positions in the transverse direction of the sheet. The method according to claim 6 or 7 , wherein during each repetition of step h), the tool does not move in the transverse direction of the sheet. It is a manufacturing method of the integral expanded metal mesh of Claim 1 or 2 ,
p) providing a metal sheet having a down-roll direction;
q) cutting the sheet to form a slit metal sheet having a plurality of rows of slits spaced apart from each other, wherein the rows of slits are aligned with the down-roll direction of the sheet. Slantingly oriented, wherein the spacing adjacent to the row of slits is a line substantially parallel to the down-roll direction of the metal sheet,
r) stretching the slit metal sheet in a direction that is not parallel to the down-roll direction of the metal sheet to form an integral expanded metal mesh;
A manufacturing method including:
