the shanghai-hangzhou high-speed railway was officially launched on october 26, and it shortened the commuting time from four hours to merely 45 minutes!

data shows, in this modern china, over one third of high-speed rail patents with the proprietary intellectual property rights were associated with new materials.

new material patents independently developed by china, such as polyurethane (pu), carbon fiber composites (cfc), thermoplastic elastomers (te), and ethylene-propylene terpolymers (ept), have been widely used in vehicles, tracks, bridges and contact wires of high-speed rails, according to wu chifei, a professor of the materials science and engineering department of the east china university of science and technology.

wu also added that those serving major national projects and economic development took up most of the new material patents.
