wherein the plurality of carbon fibers constitute at least about 70 wt % of the carrier and the at least two separate fiberglass fibers constitute at most about 30 wt % of the carrier, and
wherein the at least two separate fiberglass fibers cross each other as the at least two separate fiberglass fibers wrap along the length of the carrier.
2. The carrier of claim 1 , wherein the at least two separate fiberglass fibers are repeatedly interlaced with the plurality of carbon fibers along the length of the carrier.
3. The carrier of claim 1 , wherein the at least two separate fiberglass fibers substantially overlap vertically as the at least two separate fiberglass fibers cross the plurality of carbon fibers.
4. The carrier of claim 3 , wherein the at least two separate fiberglass fibers alternate being on top as the at least two separate fiberglass fibers cross the plurality of carbon fibers along the length of the carrier.
5. The carrier of claim 1 , wherein the plurality of carbon fibers constitute about 95 wt % of the carrier and the at least two separate fiberglass fibers constitute about 5 wt % of the carrier.
6. The carrier of claim 5 , wherein the carrier weighs about 17 ounces per yard.
7. The carrier of claim 1 , wherein the carbon fibers of the plurality of carbon fibers are continuous carbon fibers.
8. The carrier of claim 1 , wherein each carbon fiber of the plurality of carbon fibers is a 16,000 carbon fiber tow.
9. A composite reinforcement system for repairing and/or reinforcing a physical structure, the system comprising:
a carrier comprising:
a plurality of carbon fibers extending in an approximately 0 degree direction along a length of the carrier; and
a plurality of fiberglass fibers extending in an approximately 90 degree direction across the plurality of carbon fibers,
wherein the plurality of carbon fibers constitute at least about 70 wt % of the carrier and the plurality of fiberglass fibers constitute at most about 30 wt % of the carrier, and
wherein each fiberglass fiber of the plurality of fiberglass fibers crosses another fiberglass fiber of the plurality of fiberglass fibers as the plurality of fiberglass fibers wrap along the length of the carrier; and
a resin system comprising a first resin component and a second resin component, wherein the first resin component and the second resin component are configured to harden upon being mixed together,
wherein the resin system is configured to impregnate the carrier and harden after mixing the first resin component with the second resin component and applying the resin system to the carrier.
10. The system of claim 9 , wherein the resin system is an epoxide resin system, a phenolic resin system, a vinyl ester resin system, an acrylic resin system, an unsaturated polyester resin system, a polyurethane resin system, a polyurea resin system, a geopolymer resin system, a silicone resin system, an amide resin system, an alkyd resin system, or a thermoset resin system.
11. The system of claim 9 , wherein the plurality of carbon fibers constitute about 95 wt % of the carrier and the plurality of fiberglass fibers constitute about 5 wt % of the carrier.
12. The system of claim 9 , wherein the plurality of fiberglass fibers is interlaced into the plurality of carbon fibers, with each fiberglass fiber alternating between crossing over and crossing under subsequent carbon fibers across the plurality of carbon fibers.
13. The system of claim 9 , wherein a ratio of the carrier to the resin system impregnated within the carrier is about 1:1 by weight.
14. The system of claim 9 , wherein the resin system is configured to adhere the carrier to the physical structure.
15. The system of claim 14 , wherein each of the plurality of carbon fibers is a 16,000 carbon fiber tow.
16. The system of claim 9 , wherein the plurality of fiberglass fibers is two fiberglass fibers that substantially overlap vertically across the plurality of carbon fibers.
17. The system of claim 16 , wherein the two fiberglass fibers alternate being a top fiberglass fiber along the length of the carrier as the two fiberglass fibers cross the plurality of carbon fibers.
18. The system of claim 9 , wherein a thickness of the carrier impregnated with the resin system prior to hardening and a thickness of the carrier impregnated with the resin system after hardening are substantially equal.
19. A method of reinforcing a physical structure comprising:
removing a carrier from a container, the carrier including:
a plurality of carbon fibers extending in an approximately 0 degree direction along a length of the carrier; and
a plurality of fiberglass fibers extending in an approximately 90 degree direction across the plurality of carbon fibers,
wherein the plurality of carbon fibers constitute at least about 70 wt % of the carrier and the plurality of fiberglass fibers constitute at most about 30 wt % of the carrier, and
wherein each fiberglass fiber of the plurality of fiberglass fibers crosses another fiberglass fiber of the plurality of fiberglass fibers as the plurality of fiberglass fibers wrap along the length of the carrier;
mixing at least two components of a resin system together to form a resin;
applying the resin to the carrier to impregnate the resin within the carrier;
applying the impregnated carrier to the physical structure; and
allowing the resin impregnated within the carrier to harden with the carrier on the physical structure,
wherein the carrier impregnated with the hardened resin reinforces the physical structure.
20. The method of claim 19 , wherein the physical structure is a conduit assembly, a containment structure, a load bearing structure, or a building structure, and the resin is an epoxy resin.
21. The method of claim 20 , wherein the physical structure is a concrete cylinder, and applying the impregnated carrier to the physical structure includes wrapping the carrier around the concrete cylinder a plurality of times, with each successive layer of the carrier around the concrete cylinder overlapping at least part of a previous layer of the carrier.
