Carbon fiber cloth reinforcement has been a topic we often talk about.  However, its value has been recognized by numerous construction units.  Even so, for users who are still not quite familiar with carbon fiber cloth, it can't help but raise some questions: Why does carbon fiber cloth, which looks like just a thin layer, possess such powerful strength?  Here, we have to mention the tensile strength of carbon fiber cloth!

The first question comes up.  What is the standard value of the strength of carbon fiber cloth?  Can you answer it?  Someone raises their hand and answers, "The tensile strength of first-grade carbon fiber cloth is 3400 Mpa, and that of second-grade carbon fiber cloth is 3000 Mpa."

Do you think you've answered it correctly?  Actually, it's not completely right.  3400 Mpa and 3000 Mpa are just the standard values of the tensile strength of first-grade and second-grade carbon fiber cloth respectively.  Then, what is the significance of these two values in practical situations?  Can you answer this question?  Hurry up to enrich your knowledge about reinforcement!

The standard value of the "tensile strength" of carbon fiber: Generally, when we purchase or learn about carbon fiber cloth, we will mention the tensile strength of carbon fiber cloth, which actually refers to the standard value of the tensile strength.  Taking first-grade carbon fiber cloth as an example, from the perspective of physical mechanics: Carbon fiber cloth with a cross-sectional area of 1 mm² can withstand a force of 3400 N (representing the maximum tensile force that the carbon fiber cloth can bear per unit area).  The standard value of the tensile strength is a criterion.  If it fails to meet the required value specified in the original project, it means that this type of carbon fiber cloth is an unqualified product and cannot be used in this project.

As we all know, carbon fiber cloth is soft and can be pasted onto other components at will.  Carbon fiber cloth is woven from carbon fiber filaments.  During the formation process, its strength value will not be damaged, so the tensile strength of carbon fiber cloth can be well maintained.  When carbon fiber cloth is used in combination with carbon fiber impregnating adhesive for reinforcement construction work, the carbon fiber adhesive can thoroughly soak each carbon fiber filament, enabling the carbon fiber filaments to bear forces from each other and greatly improving the quality of carbon fiber cloth reinforcement.  This is also an important factor why the carbon fiber reinforcement method is deeply loved by the public.

When carrying out reinforcement projects, it is necessary to use the tensile strength of carbon fiber for design and material selection.  The tensile strength is a very important parameter of carbon fiber cloth.  Only by being meticulous about every "word" and "value" can we make rational choices and ensure a safer structure.
