  1. The letter C in the above table on the left side represents the circular section. The word in the bracket represents the name of the reinforced fiber sheet. The reinforced methods mentioned in Fig. 8 are claimed in the second phase in the numbers. FL, AL corresponding method two and method three, respectively. And Besides the letter C, if there is no word before the bracket, it is representing method one. the number outside the bracket represents the number of layers, and the last number represents the number of repeated specimens. For example, C-FL-(CoGa)1-2 represents the second specimen of the group with round cross section, the reinforced method is full wrapped with CoGa bidirectional hybrid fiber sheet, and the number of the layer is one
