The invention discloses a novel spoke made of composite materials, which comprises a spoke rod body, and the spoke rod body comprises the following components in percentage by mass: 0.5 to 0.9 percent of C, 0.01 to 0.50 percent of Si, 0.20 to 0.6 percent of Mn, less than 0.07 percent of P, less than 0.03 percent of S, 0.04 to 0.10 percent of Al, 1.45 to 2.5 percent of Cr, 0.0005 to 0.0050 percent of B, 0.003 to 0.040 percent of Ce, less than 0.003 percent of Ti, 2.5 to 4.2 percent of SCI whisker powder, less than 0.0080 percent of N and the balance of Fe and inevitable impurities. According to the invention, the SCI whisker powder is mixed in the carburizing molten steel, and all alloy elements are controlled within the specified range of the invention, so that the strength and toughness of the spoke are improved, and the service life is prolonged.
