FAQs about carbon fiber cloth are all here!

Now carbon fiber cloth reinforcement is becoming more and more common in building reinforcement. Speaking of carbon fiber cloth, I believe everyone knows the product very well. Carbon fiber cloth is also called carbon fiber cloth, carbon fiber cloth, carbon cloth, etc., and it also has unique features in the product. It is very convenient for reinforcement; because it has high strength, low density, and thin thickness, it basically does not increase the self-weight and cross-sectional size of the reinforced member. Therefore, it is widely used in the reinforcement and repair of various structural types and structural shapes such as buildings, bridges, and tunnels, as well as seismic reinforcement and structural reinforcement of nodes.

1. Structural adhesive drops on the floor, how to remove it after curing?
Just scald it with boiling water.
2. Can carbon fiber cloth be folded?
Carbon fiber cloth cannot be folded, because it is strong in tension, not good in shear, and easy to break. Like wrapping a column, what bears is tensile.
3. How high temperature can carbon cloth withstand?
Divided into unidirectional and bidirectional cloth, carbon cloth itself is fire-resistant, more than 1,000 degrees, but it depends on the fire-resistant temperature of the glue if it is pasted, and the carbon glue is 65 degrees.
4. Why are the fabrics used in construction all carbon fiber unidirectional fabrics instead of plain weave or twill weave?
Because the required characteristics of reinforced carbon fiber cloth for construction are unidirectional force and tensile strength, plain or twill cloth is bidirectional, so the carbon fiber used for construction reinforcement is unidirectional cloth.
5. Must use primer and leveling glue before pasting carbon cloth?
Primer glue and leveling glue are not necessarily used when pasting carbon cloth. If there are problems on the surface, impregnating glue must be used. If the surface of the substrate is flat, no primer can be used. Hummer's carbon glue has primer-free instructions, provided that the primer-free requirements are met.
6, 20 cm, 1m long, how many carbon tows are there in 300g/㎡?
The carbon filament weight standard (linear density) is 3k, 0.2g/m, so 12k is 0.8g/m, now it is 20 cm, 1m long, how many carbon filaments are there in 300g/㎡, that is, 300g/1m=0.8x/ 1m*0.2m, so x=75 carbon bundles, then the 12k is actually 75 12000 carbon filaments.
7. How does carbon fiber cloth play the role of structural reinforcement?
Carbon cloth is equivalent to the role of steel bars. When the main reinforcement of the beam is insufficient (that is, the flexural bearing capacity is insufficient), it is attached to the corresponding beam bottom or beam top for reinforcement, which is equivalent to increasing the stressed main reinforcement of the beam.
When the shear bearing capacity of the beam is insufficient, it is vertically attached to the side of the beam, which is equivalent to the effect of encrypting the stirrup.
