In the building reinforcement engineering, carbon fiber reinforcement is the construction structure with carbon fiber reinforced material (carbon fiber cloth) paste reinforcement, is a relatively new reinforcement method, the role of carbon fiber material in the structure to bear the stress, improve the stress state of members, limit the generation and development of cracks. Carbon fiber cloth referred to as carbon cloth, is a kind of material often used in building reinforcement construction, whether it is the property of the material itself, or the matters that should be noticed in the construction process, how much do you know? The following add solid home to introduce a few problems about carbon fiber cloth.

1. How much high temperature can carbon cloth withstand?

Single-sided two-way cloth, carbon cloth itself is refractory, more than 1000 degrees, but the paste depends on the adhesion of the refractory temperature, carbon 65 degrees.

2, structural glue drops on the floor, curing how to remove?

Just heat it in boiling water.

3. Can carbon fiber cloth fold?

Carbon fiber cloth can not be folded because of its tensile strength, shear resistance and easy fracture. Like a tool, it has a pull.

4. Before sticking charcoal cloth, be sure to use base glue and flat glue.

Bottom glue, flat glue in carbon cloth is not necessarily used, the surface has the problem of repeated use, impregnated glue has a certain use. If the substrate surface is smooth, the substrate should not be used. Carbon substrate coating instructions, as long as it is necessary to meet the requirements of substrate coating.

5. Why is the fabric used in the building unidirectional carbon fiber instead of plain or twill?

The carbon fiber used for building reinforcement is unidirectional because of the characteristics of unidirectional, stretched, plain or twill fabrics.

6. Twenty centimeters, one meter long, 300 grams per unit of carbon chain?

The standard weight (linear density) of carbon wire is 3K, 0.2g/m, so 12K is 0.8g/m, now 20 cm, 1 meter long, 300 g/m /0.8x/1m0.2m, 300 g/m /0.8x/1m0.2m is how many strands of carbon, so x/ 75 carbon chain, And then you have 12K, in fact, 75, 12,000 carbon filaments.

7. How does carbon fiber cloth play a role in structural reinforcement?

Carbon cloth is equivalent to the role of reinforcement, when the main reinforcement of the beam is not enough (that is, the flexural capacity is insufficient), paste in the corresponding beam bottom or beam top reinforcement, is equal to increase the strength of the main reinforcement of the beam. When the shear resistance of the beam is insufficient, the vertical connection of the side of the beam is equivalent to the effect of the encrypted mixing plate.
