Fiber mat with channels
A fiber mat includes natural wood fibers formed into an elongated strip having an upper surface and a lower surface, the upper surface having a first plurality of channels extending into the elongated strip, each of the first plurality of channels having a channel depth being different in a central portion of the mat than in an edge portion of the mat.
1. A fiber mat comprising:
natural wood fibers and synthetic fibers formed into an elongated strip having an upper surface and a lower surface, the upper surface having a first plurality of channels extending into the elongated strip, each of the first plurality of channels having a channel depth being different in a central portion of the mat than in an edge portion of the mat, and wherein each one of the first plurality of channels has a first wall and a second wall, the first wall extending at an angle from the upper surface toward the second wall and the second wall extending at an angle from the upper surface toward the first wall.
2. The fiber mat of claim 1 , wherein the lower surface further includes a second plurality of channels.
3. The fiber mat of claim 1 , wherein the channel depth is greater in the central portion than in the edge portion.
4. The fiber may of claim 1 , wherein the channels are not parallel to edges of the mat.
5. The fiber mat of claim 1 , wherein the channel depth is less than 50% of a mat thickness.
6. The fiber mat of claim 1 , wherein the first plurality of channels forms a diamond pattern.
7. An erosion mat comprising:
natural fibers, including wood fibers, and synthetic fibers formed into an elongated strip having an upper surface and a bottom surface, the upper surface having a plurality of channels extending into the elongated strip, each of the plurality of channels having a channel width being different in a central portion of the mat than in an edge portion of the mat,
wherein each one of the plurality of channels has a first wall and a second wall, the first wall extending at an angle from the upper surface toward the second wall and the second wall extending at an angle from the upper surface toward the first wall.
8. The erosion mat of claim 7 , wherein each channel of the plurality of channels has a first thickness and a remainder of the elongated strip has a second thickness greater than the first thickness.
9. The erosion mat of claim 7 , wherein the channels are not parallel to edges of the mat.
10. The erosion mat of claim 7 , wherein each channel of the plurality of channels has a channel depth being less than 50% of a mat thickness.
11. The erosion mat of claim 7 , wherein each channel of the plurality of channels has a first density and a remainder of the elongated strip has a second density, the first density being greater than the second density.
12. The erosion mat of claim 7 , wherein the synthetic fibers are present only in the plurality of channels.
