Review and consideration of industrialization development on para-aramid fibers and their composites

p-Aramid fibers have extensive applications in universe exploration,areospace,civil construction,defence and military due to the excellent combined properties,especially the aramid composite has already become an essential basis material in high-tech field.The characteristics of lightweight and high strength of p-aramid composites have resuited in significant effect in energy saving.So the development prospects of p-aramid fiber will be getting better with the coming of global low-carbon economy.In this paper,the types,properties,applications and the development overview of para-aramid fibers and their composites at home and abroad are introduced according to the latest status of developments and applications of aramid fiber.Meanwhile,the current problems of para-aramids and their composites are analyzed,the gaps between home and abroad in praparation technology,production efficency,capacity,equipment and market are presented and the future research direction and emphasis of p-aramid fiber and their composites are discussed accordingly.In the end,the necessity and urgency of industrialization development of para-aramid fibers and their composites are indicated from the view of scientific development and low-carbon economy.
