Why is T700g removed from Japanese Toray Carbon Fiber product specification?
T700G performance index
Toray produces a variety of carbon fiber models, there are different letter suffixes, such as T300j, T400h, T700S and T700G models, where J represents increased tensile strength compared to the basic model, h represents an increase in tensile strength and modulus compared to the basic model and the J model. s represents the model with the highest tensile strength, and G represents the model that further enhances the tensile Modulus and adhesion properties on the basis of the s model.
Most interested in, T700g all aspects of performance is very good, why the official website published data table removed T700g?
Here are some possible reasons:
for T700 products, including T700s (dry-jet wet-spun precursor) and T700g (wet-spun precursor) two categories. At present, the domestic economic development needs T700S series with lower cost, and the T700G carbon fiber with better comprehensive performance needs to be broadened because of its high price.
low-cost carbon fiber for industrial use is currently produced by most of the international carbon fiber enterprises, most of which are 12K-based carbon fibers with properties comparable to T300 and T700s, among them, T700s produced by dry-jet wet spinning is the mainstream product.
the T700G is used in aircraft structure, but it is not the main body of carbon fiber used in aviation.
