Claims (10)
1. The high-strength plate for the sole is provided with a full-sole or half-sole structure of the sole, and is characterized by comprising a high-strength fiber resin electroembroidered sheet layer with hollowed-out parts, wherein the hollowed-out area is less than or equal to 60% of the total surface area of the high-strength plate.
2. The high-strength plate for shoe soles according to claim 1, characterized in that the high-strength fiber-resin electro-embroidered sheet is a carbon fiber-resin electro-embroidered sheet, a glass fiber-resin electro-embroidered sheet or a carbon fiber/glass fiber-resin electro-embroidered sheet.
3. The high-strength plate for shoe soles according to claim 1, characterized in that the high-strength fiber resin electro-embroidered sheet layer contains high-strength fibers and a resin component, the high-strength fibers being carbon fibers of 3K to 24K in specification.
4. A high strength plate for shoe soles according to claim 3, characterized in that the resin component of said high strength fiber resin electro-embroidered sheet is epoxy resin.
5. The high-strength plate for shoe soles according to claim 1, characterized in that the high-strength fiber-resin electro-embroidered sheet has different colors and/or different textures at the main sole portion.
6. The high-strength plate for shoe soles according to any one of claims 1 to 5, characterized in that said high-strength fiber-resin electro-embroidered sheet layer further has a base cloth layer therein.
7. A method of making a high strength panel for a shoe sole, comprising the steps of:
according to the full sole or half sole structure of the sole, performing hollowed-out design electro-embroidery on the surface of the base cloth by using high-strength fiber yarns to form an electro-embroidery layer; the hollowed-out area is less than or equal to 60% of the total surface area of the embroidery layer;
and (3) carrying out composite compression molding on the electro-embroidering layer and the resin, or removing the base cloth in the electro-embroidering layer, carrying out composite compression molding on the base cloth and the resin, and demolding to obtain the high-strength plate for the sole.
8. The method of claim 7, wherein the high strength fiber yarn is one or both of a carbon fiber yarn and a glass fiber yarn; the resin is epoxy resin.
9. The method according to claim 7, wherein the mold temperature for the composite compression molding is 170-180 ℃ and the holding time is 2-5 minutes.
10. The method of claim 7, wherein the mold temperature for the composite compression molding is 120-150 ℃.
