Key technology of Advanced composite materials from aircraft to automobile

Lightweight is a critical approach for sustainable development of auto industry. Advanced composite materials (ACM), especially carbon fiber reinforced plastics (CFRP), supply the most feasible way due to the lightweight and high strength characteristics. Although there has been forty years since the application of ACM in aviation industry, characteristics of auto industry obviously differ from aviation industry, the most prominent of which is the higher requirement on production efficiency. Taking consideration of the features of ACM in combination with the important requirements of auto industry, the related research plans of developed country and the latest typical applications of ACM in automobile structure were introduced first. On the basis of this, key technologies which block potential application development of ACM in auto industry including integration design and manufacture of composite, low cost carbon fiber, efficient processing and recycling issues are discussed, it will be our best wishes if the paper is helpful to develop advanced technology of composite suited auto industry.
