Abstract: The 4 major challenges are faced with China’s automobile industry: First is the strengthening of en-ergy saving and environmental protection laws and regulations; second is the general trend of the times for using carbon fiber reinforced plastics (CFRP) car, while the production efficiency of Japanese carbon fiber companies will increase 10 times by using partial preoxidized black precursor fiber, and using microwave for carbonizing and plasma for carbon fiber surface treatment; third is the forming time both for carbon fiber reinforced thermo-plastic and thermoset composites have reach 1~3 min respectively; Forth is the gap of innovation development between advanced countries and China in power batteries is increased. So the innovative solutions should be put forward as counter measure:The high efficient and low cost large tow PAN-based carbon fiber production line, which could be increased the production efficiency by 5 times, should be imported from abroad, the R&D of above black PAN precursor should be carried on at the same time; A low cost high speed new forming curing agent for CFRP should be imported from abroad; Add the low price hollow micro-and nano-ceramic powder into car using engineering plastics and CFRP parts in order to decrease the cost to large extent, increase the compre-hensive properties and add some functions; Using para-aramid fiber tire instead of stainless steel filament tire; Speed up the pilot experiment and in dustrialization of solid vanadium battery, its theoretical energy density per weight is more than 10 times compared with lithium ion battery, now 400~600 kWh/kg have reached for solid vanadium battery in laboratory, the smaller volume and lighter weight of vanadium battery the longer last run distance for electric car due to it’s entirely new design concept, the battery need bot charge with electricity, no any safety problems, the reactant can be regenerated and reused; Using plastic light transmitting fiber for dis-play system in the car etc. these could make Chinese automobile industry striding toward worlds’ advanced or leading levels.
