On the Invention Award of Works and Papers

This paper mainly discusses about 65,438+00 books, such as Research and Development of Advanced Composite Technology, Action Principle of Composite Conductive Polymer Materials, Preparation and Processing of Polymer Materials, Introduction to Laminated Bonding Composite Materials, and Haeengegen Mechanism of Beitragzum Structure (Germany DVS Publishing House). More than 250 academic papers have been published at home and abroad, of which more than 400 are included in SCI and EI. Second prize of national defense science and technology progress (national science and technology commission, 2006), individual major contribution award of National 863 Program (Ministry of Science and Technology, 200 1), second prize of AVIC science and technology progress (aviation industry corporation of china, 1998), third prize of State Education Commission (Class A) (State Education Commission, 6548). 1989), the first national youth science and technology award/young scientist award (China Association for Science and Technology/Central Organization Department/Ministry of Labor and Personnel, 1988), and the National New Long March Commando (all-china youth federation/Central Committee of the Communist Youth League, 1987). There are about 20 international, national and national defense invention patents.

The invention of ESTM fabric made the American embargo a joke.

The international aviation community generally believes that the future aviation composite materials should have higher toughness and can withstand repeated "blows". Up to now, how to improve the toughness of composite materials used for liquid molding while maintaining the stiffness and strength of materials is still a technical frontier that attracts experts in the field of composite materials all over the world.

While the world's advanced composite leaders are committed to solving this contradiction, Hershey Group of the United States has introduced the famous liquid molding epoxy resin RTM6, which is a special high-fluidity resin, passed the airworthiness certification of the Federal Aviation Administration (FAA) of the United States, and has been used in almost all international advanced aircraft, but RTM 6 is banned in China.

In this regard, I Xiao Su said in his usual humorous tone: "In fact, RTM6 is not important to us, because with our ESTM fabric, its maximum performance potential can be brought into play."

Tested by international authoritative organizations, the impact toughness index of ESTM fabric reinforced RTM6 composites has reached the international leading level of liquid molding resin-based composites.

It is the "interlaminar structure" toughening technology and the new concept and technology of surface loading prefabrication that are first put forward in the world, and the new materials developed from this are prepreg and reinforced fabric, which have all intellectual property rights in China. This toughening technology and its special material products have been applied in many key aerospace models in China, and even improved the performance of some traditional aviation products.
