What do you mean by "T300 T700" in carbon fiber?
Carbon fiber T number refers to the level of carbon materials, industry refers to Japan's Dongli company produced a certain kind of carbon material, the industry generally refers to the ultra-high precision carbon materials. How many T refers to the cross section area of 1 square centimeters of the number of units of carbon fiber can withstand tension tonnage. So in general, the higher the T number, represents the carbon level is high, the quality is better.
Carbon fiber (carbon fiber, referred to as CF) is a new kind of fiber material with high strength and high modulus fiber with carbon content of more than 95%.
T300 and "T700" refer to the grades of carbon fibers, usually measured by tensile strength. T300 tensile strength should reach 3.5Gpa; T700 tensile should reach 4.9Gpa. At present, only 12K carbon fiber can reach the T700 level.
