Abstract

The present invention discloses an improved tool, which comprises a reinforced member; and a resin layer is coated on the reinforced member, wherein the weight of the resin layer per unit area of the reinforced member may be less than 90 g/m 2 . The weight of the resin layer may be less than 15% of the total weight of the improved tool. The present invention dramatically reduces the production costs while maintaining the application performance unchanged.

First claim

What is claimed is:

1. A fiber reinforced mesh for an abrasive tool, comprising:
a fiber fabric layer;
a resin layer coated on the fiber fabric layer; and
wherein the resin layer comprises a weight per unit area of the fiber reinforced mesh of more than 3 g/m 2 and less than 80 g/m 2 .

2. A fiber reinforced mesh for an abrasive tool, comprising:
a fiber fabric layer;
a resin layer coated on the fiber fabric layer; and
wherein the resin layer comprises a weight of more than 1% and less than 15% of the total weight of the fiber reinforced mesh.

3. The fiber reinforced mesh of claim 1 , wherein the weight of the resin layer per unit area of the fiber reinforced mesh is less than 65 g/m 2 .

4. The fiber reinforced mesh of claim 1 , wherein the weight of the resin layer per unit area of the fiber reinforced mesh is less than 45 g/m 2 .

5. The fiber reinforced mesh of claim 1 , wherein the resin layer comprises one of thermoset resins including phenolic resin, aniline-formaldehyde resin, melamine resin, epoxy resin or modified epoxy resin, furfural resin, phenol formaldehyde, furan resin, glyptal resin, polyester or modified polyester, and vulcanized rubber, or any combination thereof.

6. The fiber reinforced mesh of claim 1 , wherein the material of the fiber fabric layer is fiberglass mesh, short fiberglass, or nylon yarn, or any combination thereof.

7. The fiber reinforced mesh of claim 2 , wherein a weight of the resin layer is less than 10% of the total weight of the fiber reinforced mesh.

8. The fiber reinforced mesh of claim 2 , wherein the weight of the resin material is 5%-14% of the total weight of the fiber reinforced mesh.

9. An abrasive tool, comprising:
an abrasive substrate layer,
a first fiber reinforced mesh and a second fiber reinforced mesh that is different from the first fiber reinforced mesh, wherein each is independently provided inside or on a surface of the abrasive substrate layer,
wherein each of the first and second fiber reinforced meshes independently comprise:
a fiber fabric layer; and
a resin layer coated on the fiber fabric layer;
wherein the resin layer of the first fiber reinforced mesh comprises a weight per unit area of more than 3 g/m 2 and less than 80 g/m 2 ; and
wherein the resin layer of the second fiber reinforced mesh comprises a weight per unit area of not less than 80 g/m 2 .

10. The abrasive tool of claim 9 , wherein the weight of the resin layer of the first fiber reinforced mesh is more than 1% and less than 25% of the total weight of the first fiber reinforced mesh, and the weight of the resin layer of the second fiber reinforced mesh is more than 25% of the total weight of the second fiber reinforced mesh.

11. The abrasive tool of claim 9 , wherein the fiber reinforced meshes are all located inside the abrasive substrate layer of the abrasive tool rather than on an outer surface of the abrasive substrate layer.

12. The abrasive tool of claim 9 , wherein the first fiber reinforced mesh and the second fiber reinforced mesh are provided on outer surfaces at two opposite sides of the abrasive substrate layer of the abrasive tool, respectively.

13. The abrasive tool of claim 9 , wherein the first fiber reinforced mesh is overlaid on an outer surface of the abrasive substrate layer of the abrasive tool, the second fiber reinforced mesh is provided inside the abrasive tool, and a third fiber reinforced mesh is partially overlaid on the other outer surface of the abrasive substrate layer of the abrasive tool.

14. The abrasive tool of claim 9 , wherein the abrasive tool comprises a thickness of 0.8 mm to 5 mm and an outer diameter of 50 mm to 400 mm.

15. The fiber reinforced mesh of claim 2 , wherein the weight of the resin layer per unit area of the fiber reinforced mesh is more than 3 g/m 2 and less than 80 g/m 2 .

16. The fiber reinforced mesh of claim 1 , wherein the weight of the resin layer is more than 1% and less than 25% of the total weight of the fiber reinforced mesh.

17. The fiber reinforced mesh of claim 1 , wherein the abrasive tool comprises a ratio of diameter-to-thickness (D:T) of 8 to 62.5.
