Speaking of carbon fiber cloth, some reinforcement engineers should be familiar with it. But as an ordinary person mentioned carbon fiber cloth , is the first thing in my mind similar to the "cloth" in daily life? So can it be used for reinforcement to prevent fire? With this question, let’s take a look at it together:
First of all, I want to make it clear to everyone that carbon fiber cloth is different from ordinary cloth! It is made of countless carbon filaments under a high temperature of several thousand degrees through a special process. When it comes to its fire protection problem, in fact, the main thing is to look at the carbon fiber impregnating glue with it. Generally, epoxy resin can experience a high temperature of 260 degrees. In order to improve the fire resistance of carbon fiber, we can use the carbon fiber cloth outside Add a layer of cement mortar to protect the layer to form a protective layer. It can also be coated with some fire-resistant coatings, or even fire-resistant boards can be hung on the outside.
There are many reinforcement construction units that know the carbon fiber cloth reinforcement process. In fact, the material itself has some high temperature resistance, but the glue used in carbon fiber cloth reinforcement cannot resist High temperature, if it encounters fire and other special circumstances, the external adhesion reinforcement will cause a certain short-term failure.
The fire performance is good or not, which is also related to the quality of the product itself. Under normal circumstances, you can take a small piece of good quality carbon fiber cloth, use a high temperature lighter, or put the carbon fiber material under high temperature, and then see if it is intact.
After a few minutes of high-temperature carbon fiber baking,Everyone found that there was still no damage. From this, it can be preliminarily concluded that the carbon fiber cloth is high temperature resistant.
As mentioned above, carbon fiber cloth can be used together with carbon fiber glue. However, under normal circumstances, carbon fiber glue is not resistant to high temperatures. When the carbon fiber glue reaches the ignition point, it will ignite. Carbon fiber cloth reinforcement is used together with cloth and glue. Therefore, carbon fiber tape is not resistant to high temperatures and cannot be used as a fireproof material, nor can it be used as a reinforcement material when exposed to high temperatures.
Shibang carbon fiber cloth is woven with 12k small tow carbon fiber yarn. Used in conjunction with the matching carbon fiber impregnating glue, the cloth is soft and easy to impregnate, without bulging or falling off. After curing, the test values meet the requirements, and each square of carbon cloth can save about 0.5kg of carbon glue.
