Composite materials and related methods for manufacturing composite materials
The present disclosure relates to composites. One composite may include a resin and oxidized polyacrylonitrile fibers. The oxidized polyacrylonitrile fibers may be provided as a nonwoven fabric. An additional composite may include a resin and material scraps respectively including carbon fibers. The material scraps may be positioned to at least partially overlap one another and define a substantially continuous layer. The material scraps may be provided as a fabric and/or a plurality of loose fibers.
1. A method of manufacturing a composite product, the method comprising:
placing material scraps into a mold such that the material scraps partially overlap one another to define a first layer, the material scraps including composite chips having a cured first resin, the material scraps being non-virgin material, the material scraps including pre-impregnated carbon fiber chips;
adding a second resin to the mold including the material scraps; and
allowing the second resin to harden in the mold such that the material scraps and the second resin form the composite product including the cured first resin and the second resin.
2. The method of manufacturing according to claim 1 , wherein placing the material scraps into the mold includes the material scraps including a woven fabric, a nonwoven fabric, or loose fibers.
3. The method of manufacturing according to claim 2 , wherein placing the material scraps into the mold include forming a second layer of the woven fabric, the nonwoven fabric, or the loose fibers.
4. The method of manufacturing according to claim 1 , wherein placing the material scraps includes placing the material scraps into the mold without further processing including cutting, separating, heated, or chemically treated after being collected from selvage materials.
5. The method of manufacturing according to claim 1 , wherein allowing the second resin to harden in the mold includes the forming a shipping container panel, a shipping container floor, a countertop, a boat hull, or a storm barrier panel.
6. The method of manufacturing according to claim 1 , wherein placing the material scraps into the mold includes placing fiber glass, foam, or aramid into the mold.
7. The method of manufacturing according to claim 1 , wherein placing the material scraps into the mold includes positioning the composite chips in the first layer and a second outer layer of the composite product.
8. The method of manufacturing according to claim 1 , further comprising placing material scraps into the mold includes the material scraps being non-virgin material.
9. A method of manufacturing a composite product, the method comprising:
placing material scraps including pre-impregnated carbon fiber chips into a mold such that the material scraps partially overlap one another to define a first layer, the material scraps comprising carbon fibers and a first resin, the carbon fibers in the form of a fabric or loose fibers including the first resin applied thereto, the material scraps being non-virgin material;
adding a second resin to the mold including the material scraps; and
allowing the second resin to harden in the mold such that the material scraps and the second resin form the composite product including the carbon fibers, the first resin, and the second resin.
10. The method of manufacturing according to claim 9 , further comprising placing additional material scraps into the mold such that the material scraps partially overlap one another to define a second layer.
11. The method of manufacturing according to claim 9 , further comprising positioning an aramid material or a fiberglass material in the mold to form another layer.
12. The method of manufacturing according to claim 9 , wherein placing the material scraps into the mold includes retaining the material scraps in an initial size and shape associated with formation of the material scraps.
13. The method of manufacturing according to claim 9 , wherein allowing the second resin to harden in the mold includes the forming a shipping container panel, a shipping container floor, a countertop, a boat hull, or a storm barrier panel.
14. The method of manufacturing according to claim 9 , further comprising collecting the material scraps from selvage material.
15. The method of manufacturing according to claim 14 , wherein placing the material scraps includes placing the material scraps into the mold without further processing including cutting, separating, heated, or chemically treated after being collected from selvage materials.
16. The method of manufacturing according to claim 9 , wherein placing the material scraps into the mold includes the material scraps comprising composite chips having cured resin.
17. The method of manufacturing according to claim 9 , wherein placing the material scraps into the mold includes the material scraps having a dimension greater than 1 inch.
