What is the difference between carbon fiber cloth and aramid fiber cloth?

In the reinforcement of building structures, the bearing capacity and durability of bonded fiber composite materials are more and more widely recognized. Its advantages are short construction period, little impact on the original structure, and no increase in the self-weight of the structure. Through the continuous development of reinforcement materials, fiber composite materials are a huge family. The most commonly used fiber composite materials in reinforcement are carbon fiber cloth and aramid fiber cloth, which have different characteristics and uses. The following reinforcement home will introduce to you what is the difference between carbon fiber cloth and aramid fiber cloth?

Although carbon fiber cloth and aramid fiber cloth are high-quality fiber composite materials, there are differences in their strength. For example, the tensile strength of carbon fiber cloth can reach 3400 MPa, while the tensile strength of aramid fiber cloth can only reach 2100 MPa. From the perspective of mechanical properties, carbon fiber cloth has advantages over aramid fiber cloth, but both can meet the cohesive failure of concrete and prevent peeling damage in actual use.

Carbon fiber cloth is conductive. When the reinforcement site has strict requirements on electricity, attention must be paid to whether carbon fiber cloth can be used. Aramid fiber cloth is non-conductive and suitable for live environments. If the subway tunnel needs insulation and reinforcement materials, aramid fiber cloth must be used instead of carbon fiber cloth. In addition, aramid fiber cloth has better toughness and impact resistance than carbon fiber cloth, and is more suitable for use in dynamic load environments.

In the reinforcement of building structures, we should select suitable fiber composites for reinforcement according to the actual situation. Generally speaking, carbon fiber cloth reinforcement can meet the needs of most buildings, and has higher strength and safety factor, and it has become the main material in fiber composite materials. Carbon fiber reinforcement includes carbon fiber cloth and carbon fiber plate reinforcement. Among them, carbon fiber cloth reinforcement is another new type of structural reinforcement technology after increasing the concrete section and bonding steel.
