Rough explanation of tensile strength and elastic modulus of carbon fibers
Let's take a look at the specific parameters of the T700
Toray carbon fiber T700-12K of Japan
Monofilament diameter: 0-8u
Tensile strength (MPa) ≥ 3500
Modulus of elasticity (MPa) ≥ 2.1*105
Fiber density: 1.74-1.79G/cm³
Elongation (%) ≥1.5
If we understand the meaning of the above parameters, then it will be interesting to look at the picture provided by this netcast below
First of all, he wrote the elastic modulus as the tensile modulus, in fact, the concept of tensile modulus cannot exist in carbon fiber
Next, he wrote the units of tensile strength and elastic modulus in reverse
If the tensile strength of carbon fiber can only be calculated in Mpa, the previous figure is measured in thousands, and only 5,0 Mpa tensile strength carbon fiber is not much stronger than aluminum
In fact, a little check of the information can see that this person does not understand the concept of so-called carbon fiber at all
I don't know where to get a picture to bluff people~
There is also the important thing to build a fighter is tensile strength, and the modulus of elasticity is not an important parameter that fighters value
