CARBOCORE® composite anchors improve the efficiency of flexural and shear reinforcements with composite solutions (prefabricated fabrics and laminates).
What are carbon fiber anchors used for?
This technique is becoming increasingly widespread and is replacing standard steel techniques. Composite anchors are used in conjunction with composite structure reinforcement through bonding in order to transfer forces when the bonding surface is not sufficient.
Currently, anchors are not taken into account in either calculation models or technical standards. Furthermore, current solutions offered on the market do not guarantee identical qualities and performances from one product to another.
Epsilon Composite has imagined, designed, and developed a product that is directly manufactured through the pultrusion process: Carbocore®. The Carbocore® anchor is made from the same materials as composite reinforcements such as fabrics or laminates and therefore has the same technical characteristics (tensile strength, CTE, anti-corrosion, etc.). It can be combined, for example, with a CARBOLAM® flat laminate.
The CARBOCORE® anchor can also be implemented to traverse obstacles in order to ensure continuity of the reinforced element. In this case, the two ends of the CARBOCORE® are composed of whips that are laminated with the composite elements they bind. These anchors are dimensioned and implemented according to the available embedment depth and the quality of the existing concrete structure.
Maximize Structural Integrity with Carbocore® Carbon Fiber Anchors
Composite anchors allow for the transfer of additional forces when bonding to the support is not possible.
They are, for example, complementary for:
- Shear reinforcement in conjunction with fabrics (forces can be transferred through the slab),
- Flexural reinforcement in conjunction with prefabricated laminates (forces can be transferred through the walls).
What are the benefits of Carbocore® carbon fiber anchors?
A Carbocore® carbon anchor is composed of two elements: an “anchored” part and a “dry fiber” part. Both parts offer advantages over current solutions offered on the market.
Advantages of the anchored part:
- Easier and faster installation for the applicator compared to anchor bolts. These are usually made on site from fabrics or carbon fibers.
- Guaranteed optimal performance (similar to our Carborod®) due to the polymerized portion of the Carbocore® manufactured through Pultrusion.
Advantages of the dry fiber part:
- High-performing carbon fiber compared to current solutions involving the destruction of resin on the “whip.” The “whip” part of prefabricated anchors is subjected to resin destruction through pyrolysis or solvolysis. This attack destroys the image of the carbon fiber. The latter (the chemical binder of the fibers) allows the wetability of the fibers and the fiber-matrix bond of the composite. In this application, the “whip” part will be very difficult to impregnate. The performance of the composite is greatly weakened.
Carbocore® carbon anchors offer a reliable and efficient solution for structural reinforcement. Its unique composition of both an anchored and dry fiber part provides greater flexibility and performance than solutions available on the market. The use of Carbocore® composite anchors ensures optimal structural integrity and stability for any building or infrastructure.
