Bubbles on the surface reinforced by carbon fiber?

There are bubbles on the surface reinforced by carbon fiber. What is the root cause?

The hollow surface appears on the reinforced surface of carbon fiber cloth, which is mainly not carbon fiber cloth. The root cause is the impregnating glue (or carbon cloth glue) used with it.


adhesive for carbon fiber strengthening


In the reinforcement industry, there has always been a recognition that the thinner the impregnating adhesive (the smaller the viscosity), the better the wetting of the carbon fiber cloth, and the better the reinforcement effect of the carbon fiber cloth. However, in practical applications, due to the diversity of working conditions, the harshness of the environment, and good wettability, it cannot solve all the problems faced by carbon fiber cloth construction.


In order to meet the requirements of fluidity and wettability of impregnating glue at the same time, improving its thixotropy is an optimal choice. Thixotropy means that once it is touched during construction, its viscosity decreases rapidly, ensuring good wettability of the impregnating glue. After stopping the touch, it can quickly restore the thick state to ensure that the carbon cloth does not have empty drums and drop problems.


carbon fiber for structural strengthening repair


After continuous exploration, Horse upgraded the original thixotropic agent into nano-efficient thixotropic agent, which significantly improved the thixotropy and sensory experience.


In short, adding nano high-efficiency thixotropic agent can significantly improve the construction effect of carbon fiber cloth, can effectively solve the problem of hollow drum drop, and give full play to the advantages of carbon fiber cloth!
